Abstract

The invention comprises a combination burner for the gasification of pulverized fuels with an oxidation means containing free oxygen at ambient or higher pressures, as well as temperatures between 800-1800° C., with the ignition device of the pilot burner with flame monitoring and the pulverized fuel burner being integrated as a combination burner and all operating channels being routed separately from each other up to the mouth of the burner and the media carried by the channels only being mixed at the mouth of the burner. When the pilot burner is dismantled the eddy bodies 14 attached to its sleeve in the main burner oxidation means supply 17 can be exchanged quickly and easily and thus the main burner flame adapted in the optimum way to the reaction chamber contour of the reactor.
