ABSTRACT:
A process burner for combusting a fluid feed material which has central, middle and frusto-conical conduits in which the central and middle conduits form an annular passageway having an enlarged upstream end forming a distribution chamber to prevent high fluid flow regions which would erode an acceleration conduit at the discharge ends of the central, middle and frusto-conical conduits, the acceleration conduit forming a smooth curving surface without sharp angles from the frusto-conical conduit apex to the cylindrical discharge portion of the acceleration conduit. The distribution chamber preferably has a baffle or mixing plate angularly disposed under the fluid feed inlet to the annular passageway so that the fluid feed changes from axial to downwardly spiralling radial flow.
