HOT-WATER BOILER Russian patent published in 2005 - IPC

FIELD: heating services and hot-water supply systems.

SUBSTANCE: the invention is intended for heat of water and may be used in heating services and hot-water supply systems. The boiler contains a placed in its body furnace with the front, rear and lateral screens made out of pipes with fins, and also the upper screen made out of pipes and mounted between the lateral screens and the body intermediate screens, pipes of which are located with a displacement in respect to the pipes of the corresponding lateral screens and are supplied with two fins with formation of the convective gas flues. The odd pipes of the upper screens are linked to each other by fins forming a curvilinear surface with its salient, facing the body and the fins bending round the even pipes from above. The fins connecting adjacent pipes of the front and rear screens and also the additional fins connecting the adjacent pipes of the intermediate screens are made in the form of a curvilinear surface with its camber facing the boiler body. The fins of the pipes of the front and rear screens and also the additional fins of the pipes of intermediate screens are made gas-tight self-compensated and are placed in respect to the lateral surface of the body with formation of an air jacket, in which the air fed for burning is heated. The invention ensures increase of an efficiency of the boiler and simplification of its design.

EFFECT: the invention ensures increased efficiency of the boiler and simplification of its design.
