BOILER Russian patent published in 2022 - IPC F24H1/12 

FIELD: heat engineering.

SUBSTANCE: invention relates to the field of heat engineering and can be used to create hot water boilers to produce heat and steam. In a boiler containing a furnace part, a convective part and collectors for a coolant, the convective part contains at least one block of at least two batteries, consisting of the same type, at least partially finned steel coils, having distal and proximal ends connected to the mentioned collectors, as well as at least two U-shaped bends, while adjacent U-shaped bends are interconnected by smooth pipes. In this case, the longitudinal slots between said smooth pipes of adjacent coils of each of the said at least two batteries are closed with membranes, and the transverse slots between the distal and proximal ends of the U-shaped knees are closed with covers.

EFFECT: increasing reliability, reducing the complexity of manufacturing the boiler.
