METHOD AND DEVICE FOR BURNING LIQUID, MAINLY WATER-COAL FUEL

摘要

FIELD: boiler plants of thermal and electric power stations; heat generating plants; metallurgy; construction engineering and other industries. SUBSTANCE: flow of thermal plasma is formed inside jet of atomized fuel, coaxially relative to it; flow of hot air or mixture of air and hot gases mainly recirculating from combustion zone is organized on outer side of jet. Fairing is simultaneously used as body of plasmatron whose outlet nozzle is mounted coaxially relative to central hole of outlet flange of injector mounted on flange of prechamber for hydraulic coupling between inner and outer cavities of prechamber; injector nozzles are located in its outlet flange evenly around plasmatron nozzle. EFFECT: enhanced reliability of ignition of liquid fuel; simplified construction. 3 cl, 3 dwg
