GAS MULTIFLAME TORCH Russian patent published in 2002 - IPC

FIELD: power engineering industry. SUBSTANCE: invention specifically refers to burners fueled by natural gas with forced supply of air designed for use in furnaces of hot water boilers. Gas multiflame torch with forced supply of air has chamber to supply air, chamber to supply gas in which face walls there are made uniaxial holes, mixers coming in the form of cylindrical tubes with holes in side walls and flame tube whose internal space communicates with chamber to supply air. In accordance with invention chamber to supply gas is located between chamber to supply air and flame tube. Space inside flame tube communicates with chamber to supply air by means of cylindrical tubes of mixers tightly installed in holes of face walls of chamber to supply gas. Holes in side walls of cylindrical tubes are arranged inside chamber to supply gas. EFFECT: reduced loss of head in air conduit, reduced level of noise, more rational organization of air and gas flows, diminished dimensions, simplified design and assembly of torch. 2 dwg
