The burner is formed of a tubular housing including a central tubular passage and a boundary annular passage for feeding into the gasification reactor under high speed a carburetion medium such as oxygen or steam. At least three intermediate channels of coaxial annular sections are symmetrically arranged about the central channel and each communicates with a separate inlet conduit for feeding a mixture of powdered fuel with a carrier gas. The transition between the annular intermediate channel and the tubular inlet conduits is made such that the varying outline of the cross-section encloses the same area as the tubular inlet conduit or the annular section intermediate channel. The central tubular channel and the boundary annular channel for feeding the carburetion fluid is configurated so as to divert one stream of the carburetion fluid at an angle of about 45/sup 0/ toward the axially directed jet of the powdered fuel mixture.
