GAS HEATING BOILER Russian patent published in 2018 - IPC F24H1/00 F23J15/00 B01D53/00 

FIELD: heating.

SUBSTANCE: invention relates to a heating gas boiler. Heating gas boiler for the needs of heating and hot water supply in residential areas consists of a rectangular cabinet with thermal protection and a casing, inside which there is a furnace with a burner, a heat exchanger and a branch pipe for the exit of combustion products through the outer wall of the room. Boiler is equipped with a thermoelectric generator, made in the form of a housing with a passageway for combustion products and a set of differential thermocouples, the "hot" ends of the set of differential thermocouples of the thermoelectric generator are located in the passageway for combustion products, and the "cold" ends thereof are fixed on the outer surface of the thermoelectric generator body away from the passageway for the combustion products, in addition, the inlet of the passageway for the combustion products of the thermoelectric generator body is connected to the flange of the partial combustion products outlet, and the output is connected to the ejector mixing chamber, while the "hot" ends of the differential thermocouple kit and the inner surface of the passageway for the combustion products on which they are located are covered with a dielectric of tantalum oxide in the form of a nanosimilent glass film.

EFFECT: invention is aimed at maintaining the effective operation of the boiler during long-term operation while maintaining the normalized thermoEMF values and the corrosion resistance of the thermoelectric generator body.
