If a person in the house has a stove, a fireplace orthere is a private bath, it is worth thinking about a spark arrester on the chimney. This device is quite simple in its design and very efficient in use. The importance of having this device is hard to overestimate, because, despite its simplicity, it will carefully protect the premises from sparks, which greatly reduces the risk of a fire.
The most relevant is this device will behouse, which is built of flammable materials (wood). The chimney is an integral part of the house in which there is an oven, but it is also a source of danger, because during operation the temperature rises to high values and sparks begin to fly. It is to neutralize sparks, and this device is intended. It is engaged in "catching" sparks from the furnace, which significantly increases safety.
Sparker on the chimney should be installedeven during the construction of the building itself. This requirement is one of the main ones, provided that a solid fuel boiler or an oven is installed in the house. By its design, this element is pretty much like a deflector. However, this device is designed to protect against wind, and not from sparks. Also worth adding is that the spark arrester on the chimney will also cost less than the deflector. Saving a lot of material resources is achieved due to the fact that it can be created with their own hands from improvised means, without buying expensive materials. Installation of this device is carried out on the upper edge of the chimney.
The design of any spark arrestor consists of several key details:
The spark arrestor installed on the chimney has a number of properties that are unique to these devices:
На сегодняшний день имеется множество various schemes on which it is possible to collect a spark arrester of a very different design. However, all of them can be conditionally divided into two large groups. The first category is devices that are made in the form of a deflector. The second category is a device that looks like a casing, which is created with the help of a metal mesh.
There is only one requirement thatis considered basic and must be performed for any type of spark arrestor: this device must maintain a constant normal draft, which is necessary to maintain the normal operation of the heating system at home or the bath. It is important to make sure that the combustion products can move through the chimney without any obstacles.
The question of choosing the size of a spark arrestor on a pipeThe chimney is a purely individual matter, since this parameter will depend on the dimensions of the chimney itself. However, it should be noted that most often this characteristic is in the range from 80 to 550 mm. The size of the visor for the device will depend on the dimensions of the entire pipe.
If we talk about the principle of this device,then here it can be noted that it does not change in any way depending on the design, scheme or dimensions of the structure. It is fairly simple, but looks like this:
The principle of operation is simple, but it is quite effective.
Of course, to acquire such a device andInstall it on the pipe - it's a pretty simple solution, but it's worth noting that it's a little expensive. If the spark arrester on the chimney for a bath or a house is still necessary, and you do not want to spend money on buying it, then you can make it yourself.
There are several simple schemes, usingwhich, you can make such a device. The simplest option is to install a plug on top of the pipe, in which it is necessary to drill a few holes. It is very important to monitor one crucial parameter - the plug section. This characteristic in the numerical value should be slightly larger than the diameter of the pipe to which it is intended to be installed. This requirement is argued by the fact that the installation of the plug will be carried out on top of the pipe. A photo of a spark arrestor on a chimney of this type can be found quite simply, and it can be used as an illustrative example.
Конечно, сделать своими руками такой тип spark arrestor is quite simple, but there are some complications, the occurrence of which complicates the whole process. The most difficult aspect in the manufacture of the device is that it is not known how many holes should be and what diameter they should be. To solve this problem, some calculations are necessary. If you make a mistake at this stage, the installation of a spark absorber will result in a reduction in the draft of the chimney. In addition, there is another small drawback. The plug of this external type will eventually become covered with carbon deposits, which can cause an unpleasant smell to appear in the room.
There is another simple version of the spark arrester -This is a metal mesh, mounted on the pipe with a clamp. However, this option is also poorly distributed due to its disadvantages. The first disadvantage is that a large amount of soot appears on the grid too quickly, which will greatly reduce the draft. And the second disadvantage is that the effectiveness of this device as a spark arrester was initially quite low.
The assembly of the spark arrester is as follows:
The correct installation of this device will bedirectly depend on the size of its parts. The installation process itself is very simple, but the difficulty lies in the possible inconsistency of the diameters. If this happens, then the installation of the spark arrester will be impossible in principle. If there is an extreme need, then you can install a spark chopper without any additional fasteners, but this is a very unreliable design. You can find many different photos of the spark arrester on the chimney with your own hands, installed in this way.
The operation of this device is quite simple andIt reduces to the fact that it is necessary to regularly clean the grid of soot and other contaminants. This indicates that during installation, care must be taken that, if necessary, it is possible to remove the mesh for cleaning.
