FIELD: power engineering. SUBSTANCE: plasma generator 1 and swirler 3 embracing it are placed along axis of chamber 5 for heating stabilizing flux at distance of 1.5-2 inner diameters of chamber 5 from its inlet; ends of chamber 5 for heating stabilizing flux and outlet end of channel 6 for feeding main air mixture flow are arranged on same plane. EFFECT: reduced power requirement for steady oilless firing of pulverized fuel. 1 dwg
