To the owner who builds wooden house or a bathhouse on your site, you will have to think about not only how to equip the future building comfortably. It is very important to ensure the overall safety of the operation of this building. It is necessary to resolve the issue of a well-thought-out fire safety system.

With my heart modern bathhouse is a furnace that usually operates on solid fuel. It is necessary to ensure correct installation of both the stove structure itself and the smoke exhaust system in order to avoid the risk of poisoning by harmful gases and eliminate the possibility of fire in walls, ceilings, and roofs. And another important point - the chimney itself should not be a possible source of danger in bath room. For these reasons, a spark arrestor is installed on the chimney, which you can buy or make yourself.

You should not convince yourself that this element is not so important, because in the event of a fire you will not forgive yourself for this negligence. In addition, making a spark arrestor yourself is not difficult.

Peculiarities

Any structure associated with the combustion of fuel and the removal of harmful products outside the heated premises poses a danger to buildings. Especially when the material of the home is not fire-resistant (for example, wood).

Therefore, when building a house, it is necessary to comply with fire safety rules. This applies to both the stove and boiler, and the chimney, because along with the fuel processing process, combustion products are also thrown into the chimney. This process usually does not occur without sparks, which in turn can cause a fire. In order to protect themselves and their own home, they install a special device - a spark arrester on the chimney.

The device catches sparks by installing directly on the smoke exhaust pipe. Its design includes a body, a mesh for catching and extinguishing sparks, an element for extinguishing fire and a visor.

By and large, a spark arrester for a chimney is an ordinary mesh with small cells. The design is elementary.

We can also highlight the following features of the device in question:

  1. These devices are installed on the chimney pipes of solid fuel stoves.
  2. The cells of the mesh itself must correspond to certain sizes, namely, be no more than 5 mm.
  3. Installation of a spark arrester is mandatory if the roof is made of materials that can easily ignite.
  4. Devices are required when the chimney is installed straight (in baths, saunas, etc.).
  5. In addition, the spark arrester protects the pipe from birds and debris.
  6. Please note that when heating the stove with wood with a high resin content, you will have to refuse. Otherwise, the resin that will settle on the mesh will clog it, and the draft in the chimney will become less.

  7. The mesh needs to be cleaned from time to time.
  8. The installation of a spark arresting mesh is included in the chimney pipe design.

It is not difficult to make a spark arrestor for a chimney yourself, but you need to take a responsible approach to choosing the mesh material. Not all of them can be used; for example, when using ferritic steel or galvanized metal, this can contribute to rapid wear of the device.

The spark arrester is installed immediately after installing the chimney pipe itself.

The most the best material For the mesh, stainless steel is considered to be 5 mm thick. Stainless steel devices have excellent strength, corrosion resistance, and are characterized by a high thermal stability.

Varieties

Currently, there are a huge variety of spark arresters, differing in design from each other, but two types are still particularly popular:

  • spark arrester in the form of a stainless steel casing;
  • products in the form of a deflector.

The main condition is unhindered traction in the structure. Gases should flow through the chimney pipe easily and not encounter barriers. In addition, the spark arrester must extinguish all sparks coming through the pipes.

The dimensions of these devices can be different, it all depends on the diameter of the chimney. The diameter of the spark arrester can be either 80 mm or 550 mm. The size of the canopy directly depends on the diameter of the connecting pipe that is installed on the chimney. Review the table to understand the relationship.

The operation of a spark arrester on a chimney for a bathhouse or home is very simple. It is worth saying that all types of these products function completely similarly:

  1. Combustion products move through the smoke exhaust channel.
  2. At the tip they are prevented by a spark arrester, which changes the direction of movement along the axis.
  3. At the exit of the pipe, sparks pass through a mesh that extinguishes them.

The spark arrester may have different shapes, but the principle of operation will always be the same.

Making a spark arrester with your own hands

We have already figured out that the design of the spark arrester is simple; the device often looks like a cover that fits onto a chimney pipe.

Spark arrester in the form of a chimney cap

Buying a product is not difficult, but it will be even easier and cheaper to make a spark arrester for the chimney with your own hands. This option It is recommended for a short time, because it is not very convenient to use and has the following disadvantages:

  1. Dirt and soot quickly settle on the mesh. Over time, this will affect good draft and removal of gases from the chimney.
  2. Incorrectly calculated distance between cells. This design does not hold back sparks well, which can easily fly out of the pipe. At the same time, a mesh that is too small will cause clogging.

Spark arrestor in the form of a pipe with holes

Another option that is not difficult to do yourself (in the image).

It looks like a pipe with drilled holes. You can purchase it or make it yourself. Select the pipe a little bigger size than a chimney. Holes are drilled in it, and an umbrella is attached. Then this entire product is attached to the chimney pipe with rivets. This option looks quite simple, but the problem lies in the number and size of the holes. Wrong drilled holes may help reduce cravings. Therefore, if you make the structure yourself, then carry out necessary calculations or go the experimental route. Remember that the latter will require more time and effort.

Here is another photo of such a product.

Spark arrester for the chimney in the form of a mesh

In this case, it is necessary to take a responsible approach to choosing the mesh size to eliminate problems similar to those in the model above. This product will also have to be removed and cleaned more than once, because the holes will become clogged with dirt.

If you don't want to bother with cleaning all the time, you can install a dome-shaped spark arrester. In it, the size of the grid cells changes.

However, he does not exclude problems associated with dirt getting into the oven, because this model does not have an umbrella.

Popular models

Now let's look at more durable options. The image shows the best option in terms of functionality. It is inexpensive, and it is not difficult to do it yourself if you have the skills to work as a mechanic.

Spark arrester for chimney with mesh and umbrella

The base is made of galvanized steel with a thickness of 0.6 to 1 mm. There is no need to choose a very thin one, although it is easier to work with. We need reliability. The mesh can be welded from rods, but it is better to buy a ready-made one made of stainless steel. The cost will not be much more expensive, but the work will be much easier compared to rods. Take cells ranging in size from 3 to 5 mm. Have a grinder, metal scissors and a drill for making holes for fasteners. Due to the fact that the metal will have to be bent, you will have to prepare a workbench with a metal corner or part of a flat channel / corner.

Spark arrester dimensions

Remember to comply fire safety, especially if you have wooden building, which is heated with wood. A spark arrester is an important part of the smoke exhaust system, which will allow you not to worry about a fire when heating the stove.

A spark arrester is a device installed on the chimney of a bathhouse to prevent the emission of sparks that appear during the combustion of solid fuel. The design of the spark arrester is quite simple, so you can make it yourself. How to make a spark arrestor for a bathhouse with your own hands will be discussed in this article.

Classification of spark arresters and their application

Before making a spark arrester for a bathhouse, you need to study the theory, and only after that move on to the practical part of the issue.

There are several main types of spark arresters:

  • Metal mesh casing;
  • Deflector;
  • Other designs.

Such devices are installed in the following cases:

  • If the roof of the bathhouse is made of materials classified as flammable, a spark arrester must be installed on the chimney;
  • The spark arrester is installed on the pipe coming out of the boiler, since due to the absence of elbows, sparks can escape directly through the chimney (read: " ");
  • It is mandatory to install a spark arrester on the bath pipe if the stove runs on solid fuel.


In addition to increasing fire safety, spark arresters also protect the chimney from various external factors- for example, birds flying into it. To avoid possible problems, it is worth installing spark arresters even if there is no need for this.

When assembling a spark arrestor for a bathhouse with your own hands, you need to choose the metal correctly - not just any material will do. For example, ferritic steel will wear out very quickly because its service life is extremely short. Galvanized material cannot be used for such purposes at all.

The best option for making a spark arrestor is stainless steel with a thickness of 0.5 mm. It can last quite a long time, resists corrosion well and is easy to cook. Aluminum zinc, which also has good characteristics. True, in this case the material will have to be secured using rivets.

Having selected the material, it is worth thinking about the size of the cells. If they are large, then sparks from the bathhouse pipe will easily pass through them, and small cells will become clogged very quickly and will have to be cleaned. As practice shows, the average cell size can vary from 1 to 5 mm.

Making a deflector

Deflectors are structurally a little more complex compared to mesh analogues, but this complexity is justified - efficiency similar devices much higher. There are a few classical schemes manufacturing of deflectors, and the choice is always individual.


The simplest and most convenient design is created using the following algorithm:

  1. First, all elements of the spark arrester must be cut out on cardboard, having previously measured the diameter of the chimney pipe.
  2. The internal part of the spark arrester can be made from a piece of pipe - by choosing the right diameter, you can simply put the structure on the chimney. If there is no suitable pipe, the desired design you will have to make it yourself from stainless steel sheets.
  3. The top of the sleeve should have a slightly larger diameter. When making a sleeve from a pipe, one part of it will have to be rolled out. The length of the sleeve should reach the middle of the outer casing.
  4. To create the main casing, a pipe or stainless steel sheet is used. The casing is placed over the sleeve and secured with rivets.
  5. An apron is attached under the casing at a distance of 6 cm - a part of the spark arrester, visually similar to a curved saucer. Sparks will fall on the apron, so its dimensions must be larger than the dimensions of the casing. The same stainless steel is used to make the apron. A hole of the appropriate size is cut out in it, after which the apron is put on the sleeve and fixed by welding.
  6. A cover is mounted on top of the casing, which is slightly smaller in diameter than the main pipe.
  7. Rivets are used to connect individual parts (of course, before fixing, the necessary holes are drilled in the parts of the spark arrester).

The assembled spark arrester for the chimney for the bath is installed in its place and fixed. The structure is ready, and now the bathhouse can be used without any problems.

Manufacturing a mesh spark arrester

If the design of the deflector seems too complicated, then you can make a spark arrestor from a metal mesh. It is not as effective, but it is often chosen for its simplicity of design, which makes it possible to assemble such protection with your own hands.


The assembly algorithm looks like this:

  1. First step - pattern necessary elements made of thick cardboard.
  2. When arranging the mesh, the sleeve is not equipped with an external casing - the structure is put on top bath pipe. The sleeve is made in the same way as in the previous case - from a stainless steel sheet or a piece of pipe of the appropriate size.
  3. Two rods with a cross-section of about 5 mm 2 are welded to the mesh. A ring is bent from the mesh, which can be securely located in the internal cavity of the sleeve. When bending the mesh, you need to tap it with a hammer to reduce the stress on the metal.
  4. The ring at the junction is welded, installed in the sleeve and fixed in any way.
  5. A visor is attached to the protruding parts of the rods.

The spark arrester created in this way will provide adequate protection of the bathhouse from fire.

Other spark arrester circuits

Sometimes, instead of the traditional deflector and mesh, bathhouse owners use other devices that prevent sparks from flying out of the chimney.


The most commonly used methods of protection against sparks are:

  1. A piece of pipe is placed on the upper edge of the chimney, the end of which is tightly welded. Several holes are cut into the side of the pipe through which the smoke will pass.
  2. There's enough simple design, for the arrangement of which the mesh is welded into inner part chimney. The problem with this scheme is that the contaminated mesh will have to be completely cut out.
  3. If there are constant winds in the area, the chimney can be closed with a good deflector, but if there is no wind, then it will not be possible to use the bathhouse - there will be no draft.
  4. For protection, you can also install a chimney with several elbows. Sparks will be extinguished by bending. In addition, this design will slightly increase the amount of heat released into the bathhouse.


Conclusion

This article examined the most common spark arresters for baths. You can even assemble these devices with your own hands - it’s not particularly difficult, but that’s all existing schemes quite simple.


In any house where a heating system is installed that processes fuel and releases its combustion products into the atmosphere, there is an increased risk of fire. This is especially true if the house is made of combustible and flammable materials.

One of the sources of danger is the chimney, which during operation heats up to high temperatures and scattering sparks. To neutralize the latter, a spark arrester is installed on the chimney - a device that allows you to catch sparks flying from the system and protect the house from fire. How to make a spark arrester for a pipe will be discussed in this article.

Purpose and design of the spark arrester

When building a new home, you should always take fire safety requirements into account. Of course, they apply to the entire building and must be taken into account in all aspects, but everything related to the heating system is subject to increased fire danger. This is especially important if a solid fuel boiler or stove is installed in the house - sparks flying from the chimney may well set the roof on fire, so you will have to install a spark arrester.

Structurally, the spark arrester is very similar to its “colleague” - a deflector installed for protection from wind (more details: " "). But the functions of the spark arrester are different, and it is much cheaper - if only because you can make it yourself from scrap materials. This device Installed directly on the top edge of the chimney.


The design of the spark arrester includes several main elements:

  • The housing required to connect all the parts and attach them to the pipe;
  • A mesh that catches and extinguishes sparks;
  • A part that extinguishes the resulting flame;
  • Visor.

Spark arrestor features

The spark arrestor installed on the boiler pipe has a number of characteristic features, inherent only to these devices:

  • All spark arresters are designed for installation on chimneys connected to heating systems, operating on solid fuel;
  • The size of the spark arrester cells cannot exceed 5 mm;
  • It is necessary to install a spark arrester on the pipe if the roof is made of flammable or flammable materials;
  • Installation of spark arresters is also mandatory if the chimney design does not have turns or bends (such systems are found in saunas, bathhouses, etc.);
  • In addition to fire protection, spark arresters also protect the structure from external factors - for example, from birds mistaking the chimney for a nest.
  • It is best to make the spark-catching mesh removable - it gets actively clogged, so it needs to be regularly cleaned of dirt;
  • A spark arrester (if necessary) is always included in the design according to which the chimney system is being installed. Read also: "".


It’s easy to assemble and install a spark arrester on a pipe with your own hands; it’s much more difficult to select materials that are optimally suited for this device and will allow you to achieve maximum efficiency. A bad example is ferritic steel or zinc-coated metal - these materials wear out very quickly, so very soon you will have to think about repairing the structure.

The best option The material used to create the spark arrestor is stainless steel 5 mm thick. Stainless steel has high mechanical strength and resists corrosion well. A significant advantage in relation to spark protection is that this material perfectly withstands serious temperature changes.

Classification and principle of operation of spark arresters

Exists a large number of various spark arrester circuits, between which there are significant design differences, but there are only two main types:

  • A spark arrestor made in the form of a deflector (read: " ");
  • A spark arrester in the form of a casing made of metal mesh.

The main requirement for all types of these devices is to maintain the normal draft necessary for the operation of heating equipment. Combustion products must move freely through the chimney without colliding with obstacles. And, naturally, the flame arrester installed on the chimney pipe must perform its main function - to extinguish sparks moving through the system.


The dimensions of spark arresters are selected depending on the size of the pipe on which they will be installed. As a rule, the diameter of these devices varies from 80 to 550 mm. The size of the canopy directly depends on the dimensions of the pipe placed on the chimney. To find out the exact value, you should refer to the table, which describes the relationship between these indicators.

The principle of operation of all spark arresters is simple and does not depend on the size and layout according to which a particular device is assembled:

  • In the heating device, the fuel burns, sending combustion products through the pipe to the outside;
  • Approaching the exit, the substances encounter the spark arrester and change the direction of movement;
  • Right at the exit from the pipe, sparks enter the spark arrester and are extinguished there.

Simple spark arrester circuits

Of course, if you wish, you can always just go to the market and buy a ready-made device, having first measured the dimensions of the chimney pipe, and then install it - but such a spark arrester for a bathhouse pipe will cost a little more. In addition, the design of the spark arrester is quite simple, so assembling it at home will be almost easier.


It is very simple to make such a design, but it was not without problems. The biggest of them is the calculation of the number and size of holes that will be drilled in the plug. If the calculation is carried out incorrectly, the chimney draft will decrease. In addition, such an external plug becomes covered with soot over time, and an unpleasant odor enters the room.


Another option, which is also often used because of its simplicity, is a spark arrester made of a metal mesh mounted on a pipe using a clamp. This design is also not without its drawbacks: firstly, a critical mass of soot will very soon be deposited on the mesh, and the thrust will be significantly reduced, and secondly, the efficiency of such a spark arrester itself is not very high.

If desired, you can use the third scheme of a simple spark arrestor - the same mesh, but assembled into a dome shape. Such a device is a little more difficult to implement, but the efficiency is much higher than that of the homemade alternatives to high-quality spark arresters described above.

Making a spark arrester with your own hands

For self-assembly A full-fledged spark arrester will require the following set of tools:

  • Hammer, pliers, clamps, screwdriver;
  • Measuring instruments;
  • Grinder, scissors for cutting metal and a drill with drills;
  • Welding unit or set of rivets.

The choice of material is individual, but it is best to choose stainless steel, which has all the necessary qualities. The thickness of the mesh rods should be kept to a minimum so that the structure becomes clogged with soot as slowly as possible. It is important not to overdo it here - too thin rods can burn out after a while.


The spark arrester for the pipe is assembled according to the following algorithm:

  1. Before making a spark arrester for the chimney, you need to measure the dimensions of the chimney, according to which sketches of the future device are drawn. It is best to make cardboard mock-ups that can be used as stencils for cutting steel parts.
  2. You can buy the mesh for the structure or assemble it yourself. In the first case, everything is clear, but in the second, you need to select the rods wisely - their thickness should be in the range from 1 to 6 mm.
  3. Compound individual elements carried out by welding. The resulting joints should be carefully cleaned. The final fixation of all structural parts is carried out using rivets.
  4. Finished device mounted on the chimney pipe.

If desired, you can assemble the deflector, which will require the following steps:

  1. From metal sheet a visor of appropriate dimensions is cut out.
  2. The resulting workpiece is bent at the required angle. The bending points are fixed with metal rivets.
  3. The assembled visor is attached to the base of the spark arrester using the same rivets.

Features of installation and operation of spark arresters

Correct installation of the device directly depends on the choice of sizes of the parts used - the slightest discrepancy in diameters will lead to the fact that it will simply not be possible to install the spark arrester on the chimney. If absolutely necessary, you can install a device to catch sparks without any fasteners - but this method is very unreliable.

Operation of the spark arrester comes down to regular cleaning of the mesh from soot deposits. This imposes certain restrictions on installation - the structure must be positioned in such a way that it can be removed if necessary. It is prohibited to weld the device tightly to the chimney pipe - it must be removable.


Conclusion

It is simply necessary to install a spark arrester on the pipe - this will protect the roof of the house from fire. Even if the roof is made of non-combustible materials, it is still worth taking care of installing a spark arrestor - the radius of sparks can be wide enough to pose a danger to nearby outbuildings or other objects prone to fire.

One of the important elements of a chimney that you can make yourself is a spark arrestor. It provides not only correct, but also safe work chimney system. Some people think that they can save money on this element, but fire does not forgive mistakes. Making a spark arrester for a sauna pipe with your own hands and installing it is not as difficult as it seems. But with it you can be sure of your safety.

Nowadays, many people purchase a ready-made spark arrester in a specialized store. But why spend money if you can make it yourself. The main thing is to adhere to all the recommendations of specialists both in calculations and during the manufacturing process.

The purpose of the spark arrester and the principle of its operation

When building a bathhouse, you need to think carefully about all the points. This applies not only to the construction of walls or the arrangement of rooms, but also to the fire safety system. Since the main element of any bathhouse is the stove, then, naturally, you need to take care of its safe operation. Used for kindling solid fuel, which is not quite good quality. Therefore, combustion can be accompanied by abundant formation of sparks, which, together with hot air, rise through the chimney pipe.

Often such sparks jump out of the chimney, carrying a huge danger to everyone wooden elements baths and the roof itself. Moreover, both the bathhouse structure and nearby buildings, trees or other objects on the site may be damaged. Therefore, if you see a sparkling chimney, you should not enjoy the beauty of such a spectacle, but it is better to immediately take safety measures by installing a spark arrester.

In addition, it can be installed on chimneys for:

  • roof protection, which is made of flammable material;
  • preventing backdraft in the chimney;
  • preventing leaves, branches and other foreign particles from entering the chimney pipe.

And even though its design may be presented different models, they all function almost identically. The principle of operation is that during operation of the stove, combustion products, rising up the chimney, hit the spark arrester, changing their direction. After which they pass through the spark arrester mesh, which extinguishes them at the exit.

The purpose of installing a spark arrester is simple: to change the direction of sparks flying from the chimney and extinguish them.

Possible device options

Trying to protect the bathhouse from fire, the owners install a spark arrester. It is a simple design in the form of a chimney nozzle. There are several types of spark arrester for the chimney:

  • deflector type device;
  • mesh spark arrester;
  • simple plug design.

It is difficult to make a device like a deflector with your own hands. You will need to work hard on this design. After all, to manufacture it you will need to make all the necessary measurements, carry out calculations, and also be sure to create a drawing of the future device. Afterwards, you can move on to the process of creating a spark arrester.

This design is not only the most popular, but also effective. In addition to protecting the roof, the device prevents possible precipitation from entering the chimney pipe. It can be easily purchased in a store, but many owners want to make a spark arrester with their own hands.

But, in addition to the advantages, the design has several disadvantages:

  • the need for systematic cleaning from combustion products;
  • When the mesh is dirty, traction deteriorates.

Second option: a mesh spark arrester is a simple structure made of mesh that covers the chimney opening. It is secured with a clamp or special fastenings with brackets. But it can fit tightly onto the pipe.

IN self-production The design is quite simple. But due to its numerous disadvantages, it is not in great demand. The main disadvantages of the spark arrester are:

  • rapid contamination of the mesh;
  • short service life;
  • inability to protect the chimney from precipitation.

And the third option: a stub. The design, on the one hand, is simple, but on the other, quite risky. It is a plugged section of pipe with numerous holes drilled in it. In order to make the device effective, you will need to carefully calculate everything, choosing the right size and number of holes in the plug.

Incorrect calculation of indicators can lead to a decrease in traction, so if you prefer a spark arrester-plug, it is better to purchase this option in a specialized store.

Step-by-step manufacturing instructions

In order to make a spark arrester yourself at home, you need to take measurements of the chimney, draw a diagram of the future design, and also prepare everything necessary for work. Experts recommend using galvanized or stainless steel as the material. It has anti-corrosion properties, so it will last much longer than products made from other metals. The sheet thickness can be from 0.6 to 1.0 mm. It will be easier for you to work with thin material, although if you take a thicker sheet, the product will be much more reliable.

The thickness of the mesh rods should be as small as possible. It is recommended to use stainless steel with a diameter of 1 to 5 mm. In this case, what larger diameter, the faster the mesh will become dirty. You will also need rivets that will be used to connect the structural elements. They must be steel; aluminum is completely unsuitable for these purposes.

Creating a spark arrestor for a bathhouse with your own hands consists of the following processes.

  1. We draw a diagram of the future spark arrester on paper.
  2. We wrap an overlapping 10–15 mm mesh around the chimney pipe.
  3. Cut off the required piece.
  4. We wrap the resulting pipe head well, creating cylindrical shape, and in place of the overlap we lay galvanized metal mesh. It should extend beyond the edge of the mesh by 3–5 cm.
  5. We attach the strip to the mesh using rivets. Next, we will need to attach two more strips, which will become holders of the future spark arrester umbrella.
  6. To create an umbrella, you must first draw a circle on paper the right size. We transfer the drawing to a sheet of metal.
  7. We mark the radius of the circle on the workpiece, and, starting from it, mark an angle of 15–25 degrees.
  8. We cut off the intended area and roll the sheet into a cone with a slight overlap. We fasten the joint with rivets.
  9. We ended up with two blanks - a mesh cylinder and a spark arrester umbrella. Now we connect these two parts to each other. We fasten the spark arrestor umbrella in places of galvanized strips, which act as holders using rivets.

There should be no space left between the umbrella and the net when connecting. We do everything according to the instructions, fastening the elements tightly. Our spark arrester is ready. Now all that remains is to fix it on the chimney pipe. To do this, you can use ready-made clamps that are sold in stores, or again do it yourself.

Installation of spark arrester

When installing the device, it is important to select the cross-section dimensions. They must match the measurements of the chimney pipe. The spark arrester can be inserted directly into the chimney. This is the simplest method that does not require additional fixation. But it is not very reliable, so it is better to use another option.

To do this, the finished spark arrester is put on the chimney pipe and secured with a clamp. Such a product must be regularly cleaned to remove carbon deposits and soot. Therefore, the spark arrestor must be installed so that it can be easily removed. At the same time, experts categorically prohibit welding the structure to the chimney.

Even if you think that your bathhouse is not in danger, since the roof is made of non-combustible materials, you still should not neglect fire safety rules. The spark arrester will protect not only the roof of the bathhouse from fire, but also nearby buildings, so installation of the structure is necessary in any case, without exception.

Spark arrestors are installed on pipes to prevent sparks from escaping and spreading fire on the roof and around the building. If desired, you can make such a design yourself. To do this, you just need to correctly cut the fragments of the spark arrester. Having considered various options With such designs, you can understand exactly how a spark arrester should be created.

Ways to extinguish sparks from a chimney

To prevent sparks from touching flammable materials, you can use several methods:

Advice! If a large number of sparks fly out of the chimney, you should first try to reduce the draft and then install a spark arrester.

It is worth noting that the installation of the named structure allows you to protect the chimney from birds that begin to make nests there. Before making a spark arrestor for a bathhouse pipe with your own hands, it is worth considering in detail the process of its creation.

Features of installing spark arresters

The most common are spark arresters, which are made in the form of a deflector and have a mesh. They apply in the following cases:


Not only does a spark arrestor prevent roof fires from flying sparks, it also helps keep birds away from the chimney. Even if the risk of sparks hitting flammable materials is minimal, it is worth installing a spark arrester in order to protect yourself from fire.

When creating the described product with your own hands, it is worth remembering that not every material is suitable for such a design. If ferritic steel is used, the structure will quickly become unusable due to wear of its elements. Also, do not use galvanized sheet metal. It is best to choose stainless steel, the thickness of which is 0.5 mm, as the main material for creating a spark arrestor. This material is resistant to corrosion. At the same time, it is easy to weld.

Aluminum zinc can also be used. But it is worth noting that such material cannot be joined by simple welding. Rivets must be used to connect all structural elements. When installing a spark arrester on a chimney, you should make sure that the structure will not be broken by gusts of wind.

When choosing a material, it is necessary to correctly select the cell size of the purchased mesh. If you choose a product with too small cells, they will become clogged with soot, which will require constant cleaning of the spark arrestor. If you choose a mesh that is too large, it will not stop the sparks. It is best to purchase products whose cell size is from 3 to 5 mm.

Stages of manufacturing a spark arrestor

To make a spark arrester for a brick pipe, the following tools and materials are needed:

  • stainless steel sheet, the thickness of which should be in the range from 0.5 to 1 cm;
  • metal mesh with high rigidity;
  • steel rivets necessary to connect some structural elements;
  • metal scissors;
  • Bulgarian;
  • welding machine.

It is worth remembering that if sparks periodically fly from the pipe, then you should not install a simple visor on it. Such devices are not able to stop flying sparks. To save money, you don't have to buy finished goods, but do them yourself, because this does not require experience in performing such work.

The simplest design is made as follows:

  1. First you need to purchase a metal mesh. It is important to choose a rigid material, since it does not deform when exposed to high temperatures.
  2. After this, you need to prepare a piece of metal pipe.
  3. Then a rectangle is cut out of the mesh, the length of which is equal to the diameter of the pipe.
  4. After this, you need to wrap the pipe with mesh and secure it by welding. On at this stage It is important to securely fasten the mesh so that it can withstand strong winds.
  5. At the next stage, the cone is secured over the mesh. The fastening takes place on metal brackets so that there is a small distance between the mesh and the cone.
  6. On final stage the finished spark arrester is fixed to the pipe using metal brackets.

Creating a spark arrester similar to a deflector

It is worth noting that designs created like a deflector are more effective than products with a mesh. Spark arrestors are often created for a brick pipe similar to the Tsaga deflector, to which an apron is added to catch sparks. Creation occurs as follows.
