GEAR TO SUPPLY WATER-AND-FUEL EMULSION TO FURNACE OF BOILER Russian patent published in 2002 - IPC

FIELD: fuel-burning facilities. SUBSTANCE: technical result of invention consists in formation of more developed atomization surface of water-and-fuel emulsion thanks to creation of several parallel atomization planes. Gear to supply water-and-fuel emulsion to furnace of boiler includes atomizers with two fuel nozzles made of heat-resistant material which are positioned uniaxially and in opposition and are joined to spiral heat exchangers by threaded heat resistant couplings. Heat exchangers are linked to common tube mounted for displacement in horizontal direction and turn around own axis and connected to source of water-and-fuel emulsion. Fuel nozzles are interconnected with the aid of bar placed uniaxially with nozzles, having diameter under that of outlets of nozzles and provided on ends with left-hand and right- hand threads. In nozzles there are anchored spiders with holes uniaxial with nozzles having left-hand and right-hand threads into which ends of bar are screwed. Cylinders which internal surfaces have several spiral grooves arranged equidistantly one relative another are located across outlets of nozzles. Inner diameter of cylinders minimally exceeds diameter of bar. EFFECT: formation of more developed atomization surface of water-and-fuel emulsion. 5 dwg
