METHOD OF AND PLASMA PULVERIZED-COAL BURNER FOR LOW-GRADE COAL COMBUSTION

摘要

FIELD: power engineering; thermal power stations and boilers. SUBSTANCE: plasma electric arc is generated in air-mixture feed channel made in burner; to this end, mentioned channel is primarily used to generate auxiliary plasma electric arc and its plasma currents excite main arc; in the process, plasma generator-igniter is displaced along rod-type electrodes as they wear down by erosion. EFFECT: provision for oilless ignition; improved stabilization of pulverized-fuel burning. 2 cl, 3 dwg
