DEVICE FOR CLEANING AND RECOVERY OF FLUE GAS HEAT OF GROUP OF HEAT GENERATORS OF RESIDENTIAL HEATING SYSTEMS Russian patent published in 2016 - IPC E04H12/28 F23J15/02 

FIELD: heat-and-power engineering.

SUBSTANCE: invention relates to a power system and can be used for cleaning flue gases from harmful impurities of heat sources of apartment heating systems. Device for cleaning and disposal of group of apartment heat generators of heating systems including flue gas duct made of corrosion-resistant material, reported on opposite edges of atmosphere through smokestacks fitted with baffles, and laid on top floor of building. Bottom of box is provided with holes connected to individual channels and sewage riser chimney, and are made with inclination I towards sewage riser. Upper edges of individual chimney pipes are disposed above bottom surface of box by a value δ. Perforated container is filled with pumice granules made from metallurgical slag basicity module M > 1 and granule diameter of 5 to 10 mm. Pumice granules are placed inside box in perforated baskets installed at a height H₁ from its bottom on support rails and vertical perforated walls. Over perforated baskets at a height H₂ roofed box located washing, perforated bottom, pipes, ducts connected to outside through shut-off valve to collector of tap water.

EFFECT: technical result is to increase reliability and efficiency of device for cleaning and disposal of group of apartment heat generators of heating systems, flue gas.
