Chimney – a vertical pipe or conduit of rectangular or circular cross section to produce thrust, and the flue gases from the heat generator (boiler, furnace) and chimney up into the atmosphere. Chimney – a pipeline or canal to flue gases from the boiler to the chimney or out through the wall of the building. Stainless steel flues – recently the most common solution for the flue gases, and it is no accident they are durable, Acid-proof, leak-proof and less labor-intensive to install than other chimneys. This article will address the main aspects of the choice of stainless steel flues for heating appliances. Ovens and stoves fireplaces bath and stoves for saunas, ‘classical’ and ‘cluster’ fireplaces, gas and diesel boilers – are all space heaters. In fact, each of which requires its “own” the chimney, ie chimney, focused on a specific heating device. That’s because stainless steel is different in their chemical composition, from which it is defined and its heat resistance and resistance to corrosion. Corrosion resistance – this is not the latter is stainless steel, because of increased efficiency of heating appliances, the chimney is excessive kondensatoobrazovanie.

Due to the fact that modern space heaters give maximum heat produced, temperature of exhaust gases in the chimney is not high enough because of what condensation. Just one of the reasons for its formation is the fickleness of the heating appliance (stove, fireplace). Because cooling of the flue leads to . Reduce the allocation of the condensate in such a case may increase heat-insulating layer between the outer and inner loops of pipes. By itself, the condensate is not terrible, but unfortunately, he interacts with the smoke and soot.

As a result of this interaction is formed by several kinds of acidic compounds, which corrodes stainless steel. With regard to heat insulation between the circuits of pipes, it should be: non-flammable, are not destroyed by heat or other factors that do not emit harmful substances. Its thickness depends on: flue gas temperature, outdoor temperature and other factors which provide safe use of the chimney. Types of chimneys. At the moment there are three main types of stainless steel flues: single-circuit, dual and coaxial. Single-loop (single wall) chimney used for indoor installation of the building and as a liner in brick chimneys. Dual (double-walled, insulated, sandwich), the chimney is used to set both indoors and outdoors. Stainless steel flues can have both vertical sections and inclined, and even horizontal. For this purpose a sufficiently large number of items, such as: tees, elbows, condensate trap, plugs, flanges, pipes, gates, baffles, umbrellas, headroom, etc. The choice depends on the chimney: the chimney installation option (external or internal placement), building construction, installation place the device in the building, the most radiator.
