Novel mixed burner for solid, liquid and/or gaseous fuels in which the solid fuel is conveyed within the burner in a sprayed state by means of a central tube which is joined directly to the outer tube, in which central tube is housed the pipe with the fuel oil injector. In the improved burner which is proposed shaping and stability of the flame is obtained by means of a reduced- pressure effect derived from the injection of a portion of the primary air via orifices substantially perpendicular to the axis of the burner. <IMAGE>
