A few words about the structure and operation of the instrument
Sparks damper put on the chimney, will be a real boon, especially if the house or bathhouse located near the forest. After all, the fiery spark in windy weather can easily overcome a 300-meter distance up to nearby pines.
And this is a direct threat of fire from which to insure themselves and their property by placing a protective device on the chimney.
Why do I need a quencher sparks
Device for extinguishing sparks necessary if the materials which can easily ignite in contact with them sparks were used for roofing. Of course, this decorative cover - this is not the best choice. But, in practice, often neglect safety in order to realize the original design ideas.
A spark arrester is required if the area of territory is a building baths, saunas and other facilities where you plan to warm up to a high temperature. The tree from which the walls are made baths can easily be ignited by accidental spark.
Well, when the roofing is selected refractory material which can withstand repeated collision with fire sparks
And of course, when the house is equipped with a private heating system and hot water supply. Here, the boiler will heat up to a high temperature to ensure that the demand for heat and hot water. Without installing damper sparks chimney arrangement we can not do.
When the heating of the boiler is formed a high fever, and the sparkle of the direct chimney easy to take off the street, forming a breathtakingly awesome sight
The structure and operation of the spark arrestor
A device for extinguishing sparks has a simple structure and simple principle. Depending on the model, the spark arrester will vary its structure and appearance.
However, in all embodiments is the presence of common metal element, made of a mesh or a solid sheet. Also, there is the foundation on which all other parts are attached and the cover, which prevents the free escape of sparks.
Components: 1 - body, 2 - Net, 3 - spark suppression element 4 - a cover. Device for breaking and extinguishing sparks may have a different structure. A role as a spark arrester may perform mesh, and one-piece metal plate (+)
The operating principle of the spark arrester is to prevent the free movement of sparks flying across the chimney. This is facilitated by its structure, provides multiple change of direction of motion sparks running across various obstacles.
So, hit the metal net with fine mesh, a spark is broken, its speed is reduced, and the direction of change. Repeated collision with another obstacle to the metal surface structure, a spark, and all can go out and not taken off outside the chimney.
It is important that the spark arrester is designed to be free movement of gases, but prevented the movement of sparks
Grid of stainless steel with fine mesh is able to prevent sparks, but it will not affect the free movement of gases outside the flue.
Types of devices for extinguishing sparks
Spark arresters are of different shape, size. Yes, and the element responsible for the extinction of sparks, is different. Moreover, you can buy in the store ready to spark arrestor on the chimney or to make his own hands. It all depends on the skill and personal desire.
Often use the instrument 2 in one - a spark arrestor + deflector that can get rid of sparks and add traction
You can buy a ready to install the spark arrester on the chimney, to choose the most attractive model. The benefit of manufacturers offer a variety of options, which differ not only in appearance, but also the price.
Moreover, the better the performance of the material used in the manufacture of the device, the higher will be its cost.
The metal cap is the budget proposal. Yes, and make their own hands it will be easy
Most often used by such spark arrestors:
- cap of a metal grid on the well head pipe;
- deflector with a metal mesh;
- Deflector with skirt for extinguishing sparks.
These are the most popular options spark arresters, which is easy if you want to build with their own hands. And a simple structure will be on hand at independent manufacturing. We just need to properly prepare and make preliminary measurements.
sparks damper may have the most intricate form, sold by the manufacturer. But its purpose instrument performs excellent
It may be several layers of mesh with a mesh of different diameters that allow sparks good break, regardless of the direction of its movement
Sometimes homeowners to install their chimneys deflector n-shaped type. Its special shape allows multiple collision sparks obstacles

A variety of solutions for extinguishing sparks allows you to choose the best option for your chimney. Moreover, not only in appearance, but at a price, which is an important factor when selecting a model.
Among the various models of spark arresters offered by manufacturers, you can choose the right and its own likeness make the device using the materials at hand
Step by step construction of the spark arrestor
For the self-assembly of the device for extinguishing sparks need simple materials, tools, and a couple of hours of free time. Moreover, it is possible to choose an optimal model, shape and size. Yes, and the choice of material is unlimited - the quality of the final device will be an order of magnitude higher than purchased.
The choice of models and materials
First you need to decide which model will serve as a spark arrester. From this flow of materials, the tools and the time required for manufacturing the device will depend.
If you decide to make a spark arrester, consisting of a lid and a metal pipe, there is a lot of time is not required - all quickly and easily
When will produce a spark arrester deflector functions, you need to:
- take your measurements with the inner surface of the chimney - diameter;
- prepare metal sheets of stainless steel pipes;
- if necessary, buy a metal grid with the desired cells;
- prepare tools - metal shears, grinders, drill, pliers, hammer, pencil, compass, Riveter, ruler, paper;
- purchase the desired metal clamp diameter rivets.
If there prokatochny machine, the product received almost as a factory. Otherwise, do not worry - all work can be done with a hammer.
Also, if there is no riveting, you can use the welding machine. The main thing is not to burn the extra holes in the connection joints.
The pipe should be chosen with the same diameter as the chimney itself. After subsequently spark arrester is worn on the flue pipe
It is advisable to rivet machine was of good quality, otherwise it simply can not cope with their work and have to use alternatives for the connection joints
The tools that will be needed for the manufacture of the spark arrester, depending on the model chosen, as well as a set of consumables
Stainless steel sheet can be selected solid or perforated, in the form of mesh. The main thing that the cells were no more than 5 mm

Set of tools
Stainless Steel Sheets
In choosing the material should be preferred stainless steel sheets. Moreover, it may be solid and perforated, which may be used instead of the metal mesh. The thickness of the sheet should not exceed 5 mm - with a thick material is difficult to work.
Metal mesh also better to take the stainless steel, giving preference to the one which has a mesh size of 4-5 mm. The larger size of the openings is not as effective against sparks, while too small cells can obstruct the free movement of gas and smoke.
The optimum mesh size of the metal mesh stainless steel - 3-5 mm. If their size is less than 1 mm, it is better to buy another grid
Production of the prototype spark arrestor
When the spark arrester model is selected, you are ready to plotting on paper in advance to take your measurements. For this useful paper, compasses, pencil and ruler. It is important to perform all life size and accurate - it will continue to be used as a prototype of the final product.
When all the items on paper drawn should be added at the edges 1-2 cm - is allowances for connection parts between the components.
A paper prototype can not do if there is an experience of manufacturing vents and other devices for the home
After a pair of scissors must cut the paper prototype and assemble all - it will allow to evaluate the appearance of a future product. It is at this point, you can make adjustments. If you are satisfied, the diameter of the pipe is suitable, then you can proceed to the depiction of the details of the metal material.
Build products with their own hands
The necessary details of which will be assembled spark arrestor, after a sketch should be carefully cut with scissors for metal. This is likely to be an umbrella, stripes, umbrella holder stainless steel cylinder of mesh, a metal pipe cut the proper diameter.
If you forgot to buy the pipe, can be of stainless steel of the continuous sheet to cut the desired part and collect it using a rivet mechanism with rivets.
The number and name of the parts depends on the model you have to collect - it is easier than, the less likely you will need
Then have to collect all the details one by one and fasten them together using the Riveter. If no such tool, welding machine can be used for the connection. In this case, the allowances for joints required less than 2 cm and the seam had an attractive appearance, it will further process the grinder.
When assembling the spark arrester is important to consider the peculiarities of a particular model. If it's just a spark arrester functions without the deflector, the gaps between the parts should not be - all the sparks flying out of the chimney should meet an obstacle in its path.
At an improvised spark arrester shape of the skirt can be anything - until the square. The main thing is that the outer edges are slightly raised
When the damper is going to spark deflector function, you must first build himself a deflector. After - at the bottom of the base at a distance of 6 cm from the lower edge of the upper nozzle holes with a drill to make connections with the skirt.

The metal skirt or plate in the form of plates with folded edges and a middle hole for tube-deflector spark arrestor
Sometimes handyman instead damper facilities sparks, improve the chimney.
Types manipulation depends on the type and shape of the tube:
- a metal bore holes in the upper portion and completely cover the headroom solid stainless steel cap;
- If the chimney square shape, the top simply attach the metal grid;
- reduce craving a bit, closing the valve to reduce sparking.
The first option is the most time-consuming. And the holes will still eventually get clogged with soot and require cleaning. Therefore it is better to choose an option in which the spark arrester is easily removed.
For curved end walls of the chimney is often used a grid, which put directly on the pipe, choosing a convenient way to mount
Large holes are not able to extinguish the spark. For this to be put on the chimney additional mesh metal cylinder with small-cell - up to 5 mm
With sufficient dexterity and accuracy of the finished result can come out better than bought in a specialty store

Installing and fixing device
When work on the assembly completed spark arrester, to be the last step - setting it on the chimney. You will need to climb onto the roof, and if the height of the pipe is quite large, it will invite the assistant.
When installing a spark arrester is better to use personal protective equipment for the respiratory system, to not breathe combustion products
To install the required rivet mechanism with rivets or metal clamp. Sometimes you can find tips masters, offering not just fooling and welded to the pipe chimney spark arrestor. This is bad advice - according to the rules of fire safety design of this element should be removable.
Therefore it is best to use the clamp the required diameter, which will securely fasten the spark arrester on the chimney.
Clamp allows tightly secure the damper on the tube sparks. Moreover, it is convenient to shoot if necessary to clean the grid with smoke and debris
If the installation of rivet used, the pre-bore holes at the desired distance on the tube and on the spark arrester. Then, the product itself is put on the chimney and put rivets riveting. Okay, so that they are made of stainless steel. This will extend the service life.
Features care spark arrestor
The complexity of care device for extinguishing sparks, mounted on the chimney it depends on the model chosen by the building owner.
First option - cap of a metal grid. In this case, will periodically check its state - it can become clogged with combustion products, other debris, brought by the wind.
This grid, especially when the fuel is used for heating with a high resin content, need to be cleaned of soot and burnt quite often. Also, if the material for the production was chosen cheaper soon need to replace the spark arrestor new.
When procleaning structure in which the mesh is set as a damper designed for collision with sparks will disassemble construction. And it is certain inconveniences
Frequent trips to the roof to clean the mesh and can hardly be called an enjoyable experience. Yes, even when from time to time need to change the metal grid on the chimney. Therefore, it is better to choose a high-quality material for the manufacture of the spark arrester.
The second option - baffle with mesh inside. There also need to periodically clean the metal grid cells clogged combustion products. The more debris collects on the mesh itself an element of the device, the harder it will be the process of removing smoke. And it is fraught with serious trouble.
The third option - Deflector with skirt. There will periodically check to the leaves, butterflies and birds are not shut down small holes used to remove water from rain and melting snow. Remove the device from his workplace and do not have to be cleaned. This is the simplest model of service.
The fourth option - spark arrestors made of metal alloys prone to corrosion. Such products very quickly come into disrepair. This should be taken into account at the stage of selection of the material.
To protect themselves from the need to construct the spark arrester annually, better immediately choose a quality stainless steel 5 mm thick. The same applies to the metal mesh - it must be resistant to wear, the best stainless steel.
Grid for producing sparks absorber must be heat-resistant, wear-resistant walls with a thickness of 5 mm
spark arrester test is mandatory when chimney cleaning.
