Flue, creating natural draft, serves for branch from the room of combustion products of fuel. Safety and efficiency of all heating services depends on the correct selection of material of production, and mounting of flue.
Instruction
1. The brick flue is used for a long time. Need for it has arisen when people have begun to heat houses furnaces and fireplaces. However it is correct to lay out flue it can do only to the true master stove-setter, and to find it today – task not from simple. Besides, brick flues do not approach the majority of modern heating units. The brick flue demands more thorough leaving, and rectangular or square cross section in combination with surface roughness of walls of the channel complicates passing of gases.
2. As worthy alternative to brick the flue from creep-resisting stainless steel will serve. It is much easier than the predecessor therefore does not demand construction of the additional base. Pipes for steel flue are easily mounted and are suitable for work with different modifications of furnaces and boilers. Corrosion resistant, durable pipes have the optimum size of section for removal of exhaust gas. The smoothness of walls interferes with sedimentation on them of soot, and the round shape of the channel, unlike square and rectangular, does not give the chance to be formed to local turbulences which hinder the movement of gas streams.
3. The flue from the clay shamotny pipes enveloped by stainless steel or lightweight-aggregate concrete has the same qualities that the steel device. Elements of shamotny systems consist of internal pipe, the insulation course based on basalt breeds and external casing from stainless steel or light foam concrete. The cost of such flue which is slightly higher than steel pays off longer term of operation.
4. For fans of exotic the modern market offers flue from glass. Its main advantage is the absolute lack of corrosion. However now purchase of this system and its mounting demand considerable monetary expenses.
