ABSTRACT:
A burner for burning a pulverulent fuel has a divergent burner quarl at the narrow end of which a pressure liquid or compressed air burner for combustion-assisting gaseous or liquid fuel opens. The feed means for the pulverulent fuel comprise a number of separate discharge passages which are arranged in a ring and which open in the divergent wall portion of the burner quarl at a distance from both the burner nozzle and the inlet for secondary or main combustion air and which are directed obliquely inwardly towards the axis of the burner and are spaced from each other a distance which substantially exceeds the extension of each outlet of the discharge passage along said ring.
