Abstract:
Disclosed is a burner for oxidant gasification of pulverized fuels under high pressures, e.g. 80 bar, and temperatures, e.g. 1200 to 1900° C., in reactors with liquid slag removal for oxygen gasification. The individual pulverized coal supply tubes in the burner are inclined toward the burner axis in the direction of the burner mouth, are implemented equiareally from the burner inlet up to the burner outlet, and end at the burner mouth adjacent to the oxidant outlet. Owing to the pulverized fuel feeding elements being implemented right up to the burner mouth and the instantaneous entry of the pulverized coal into the rotating oxygen stream there is no longer any areal discontinuity at the dust outlet, since here the pulverized coal stream is immediately sucked into the oxidant stream. At the outlet of the media the individual pulverized coal streams merge into a single rotating pulverized coal/oxygen stream, thereby achieving an even flame spread and stabilization.
