FIELD: power engineering.
SUBSTANCE: invention refers to the sphere of power engineering and may be used in heat power plants, boiler plants. Plasma ignition device for dust coal fuel comprises body, rod electrodes (5) to generate electric arc, fuel line (7) and pipeline (8) of secondary air. According to invention, body is separated with transverse partition (3) into resonant (1) and cooling (2) chambers, besides, in the partition centre (3) there is a passage (4) for secondary air, where rod electrodes (5) are installed with the possibility of longitudinal displacement, besides, their working part is guided inside resonant chamber (1).
EFFECT: provides for black oil-free ignition and stabilisation of dust coal fuel burning.
