GAS HEATING MODULE Russian patent published in 2014 - IPC F24H1/10 

FIELD: heating.

SUBSTANCE: invention relates to water heating equipment, i.e. to decentralised heat supply and hot water supply plants of domestic, production and public buildings. A gas heating module consists of a metallic housing filled with water. A U-shaped heat generating element with a burner assembly is located inside the above housing. The gas heating module also consists of a gas and air supply system, a gas duct, a flash tank, and connection pipes for water, water drain in case of repair. The convective part of the U-shaped heat generating element is made of two gas ducts of rectangular section. Steel cylindrical studs are welded to two opposite side walls of each of the gas ducts in a staggered order across flue gas flow. Oppositely installed rows of studs form double rows at assembly of gas ducts.

EFFECT: improving energy efficiency, reducing mass and dimensional characteristics, improving strength and reliability of the design, improving heat exchange efficiency of the convective part of the heat generating element.
