HOT-WATER BOILER (VERSIONS) Russian patent published in 2020 - IPC F24H1/40 

FIELD: heat power engineering.

SUBSTANCE: invention relates to water heating devices and can be used for heating residential buildings and structures. Hot-water boiler can have several versions. In compliance with first version, it comprises housing, furnace chamber with door, chimney, water jacket with water inlet and outlet branch pipes arranged on furnace side and rear walls. In upper part of furnace chamber water jacket is supplemented with water-filled stud, which in lower plane has middle edge, located below side ribs in height, thereby forming two inclined surfaces to side walls of furnace. In the second version, the boiler has a housing, a furnace chamber with a door, a chimney, a water jacket with water inlet and outlet branch pipes made on the side and rear walls of the furnace space. On lateral sides at rear wall of furnace there are side vertical chimney pockets, made in horizontal section in trapezoidal shape, as integral part with furnace chamber side walls.

EFFECT: result of this invention is: high efficiency of hot water due to increased area of heat exchange between water jacket of boiler and gaseous waste of fuel combustion, due to use of water-filled stud and side vertical chimney pockets, creation of uniform heat exchange with water jacket of boiler.
