BOILER FOR HEATING GAS

FIELD: household fuel-consuming equipment.SUBSTANCE: invention relates to household fuel-consuming equipment and can be used in gas flow and capacitive water heaters, heating devices for heating purposes, water supply of apartments in apartment houses and industrial premises. Heating gas boiler consists of rectangular cabinet with warm protection and casing, inside of which furnace with heating pad is located, heat exchanger and combustion product outlet pipe through outer wall of room, installed vertically and comprising cone-shaped nozzle with curvilinear planes and guides and swirling ribs, cassette with adsorbing substance, hermetically installed in combustion products outlet branch pipe between rectangular cabinet casing with warm protection and inner surface of room outer wall. Cassette includes vertical housing with upper and lower headers, side walls, which with sectional partitions installed in it are made zigzag-shaped and form in each section diffusers and confusors located relative to adjacent sections in staggered order. Combustion product outlet pipe includes an ejector installed along the combustion products flow direction and a combustion product partial discharge flange, which is connected to the thermoelectric generator made in the form of a housing with a through channel for combustion products and set of differential thermocouples. "Hot" ends of thermoelectric generator differential thermocouple set are located in combustion product passage, and "cold" ends thereof are fixed on outer surface of thermoelectric generator housing away from feed channel for combustion products, besides, input of passage channel for combustion products of housing of thermoelectric generator is connected to flange of partial discharge of combustion products, and outlet is connected to ejector mixing chamber. "Hot" ends of set of differential thermocouples and inner surface of passage channel for combustion products, on which they are located, are coated with dielectric from tantalum oxide in form of nano-like glass-like film, besides on inner surface of ejector part expanding in direction of movement of combustion products there are screw-like grooves with profile in form of swallowtail, and its outlet hole has circular groove, connection with contaminant removal device. Pollution removal device is made in the form of housing with cover and combustion products inlet and outlet pipes, wherein cover is connected to reflective partition and symmetrically located
