HOT-WATER FLAME-TUBE BOILER Russian patent published in 2018 - IPC F24H1/00 

FIELD: heating.

SUBSTANCE: invention is intended for hot water boilers and can be used in heat power engineering for their production with improved heat engineering characteristics. Fire-tube boiler includes a fire tube with a burner unit, surrounded by a water jacket, rotary chamber, which provides the direction of reversible flue gases into the smoke tubes, outer shell of the boiler shell, dispensing tray and flue cover, differs in that the flame tube to the rear tube board is fixed through the compensator; water jacket is a heat exchanger in volume enclosed between the front and rear tube plates, the outer surface of the flame tube and the shell of the outer shell of the boiler, which receives the radiant flux, intensified by the glow of the screen of the mesh and convective component of the combustion products, while the heat exchanger is made constructively with air heating in it due to exhaust gases; between the burner device and the inner surface of the flame tube a screen is installed perforated, amplifying the radiant component; on the water supply there is a distributing chute, perforated with holes, which ensures the improvement of hydrodynamics; turbochargers are located freely in the boiler's smoke tubes.

EFFECT: technical result of the proposed invention consists in the most effective combination in single volume of developed radiant and convective heating surfaces.
