Oval chimneys
The KO system is used to remove exhaust fumes from appliances with an open combustion chamber, fired with ecological solid fuels. In this type of boilers, the air necessary for the combustion process is taken from the room in which it is located
device. In turn, the combustion products are discharged to the atmosphere via the chimney. Elements of this system are made of oval pipes and fittings intended for shafts with a rectangular cross-section. The choice of material, construction and technological processes used in production are aimed at adjusting the parameters of the flue gas pipe to changing working conditions and different flue gas temperatures. Pipes and fittings of the KO system are produced in two wall thicknesses - 0.8 mm and 1 mm. They have pin-muff ends that allow for tight connections.
