CANIADIAN PATENT APPLICATION OF OLLE LEINNART SIWERSSON ARNE EVERT WALL and JAN AKE TORSTEN LOODBERG FOR BURNER FOR A SUSPENSION OF FINE-GRAINED COAL IN LIQUID Abstract of the disclosure. Burner for a suspension of fine-grained coal in a liquid, particularly water, which burner operates according to a combination of the rotary burner and toroidal burner principles. The fuel is supplied axially behind a transverse distribution baffle within a conical rotary body. At least the outer rim portion of the inner side of the rotary body forms an angle of 35-80° with the axis of the burner. At the outer edge of the rotary body there is an annular air supply nozzle for supplying a conically diverging outwardly directed air stream. Outside the air supply nozzle and at a radial distance from it, there is a conical guide baffle (18, 48) which at its outer end may be curved inwardly and which, together with the diverging air stream, serves to produce a positive recirculation of combustion gases, non-combusted coal particles and ash particles in a direction back towards the rotary body in accordance with the toroidal burner principle
