HEAT-TUBE WATER BOILER Russian patent published in 2015 - IPC F24H1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to heat engineering and can be used in water heaters incorporated with heating and hot water supply circuits. This boiler comprises cylindrical body to house water feed and discharge pipes. Said body is closed from the front by perforated bottom with opening and neck for burner to be fitted therein. From behind, it is closed by bottom with flue gas escape hole. Said hole accommodates heat tube aligned therewith, closed by front and rear bottoms and provided with water-tube convective section. Boiler water section is composed by circular space enclosed between heat tube and cylindrical body. Said space is divided by multistart screw web with constant or variable pitch into separate channels. Sizes of the latter ensure the heat carrier design rate. Webs are arranged in convective section pipe channels to allow heat carrier circulation.

EFFECT: higher heat efficiency of the boiler with preset dimensions owing to better heat exchange.
