Abstract

Method and apparatus for injecting gasification medium into particle-loaded gasification spaces of fixed-bed, fluidized-bed or entrained-bed gasifiers by means of gasification-medium nozzles, wherein the supply portion the isorate of the gasification medium in the gasification-medium nozzle does not fall below a minimum value, and in the adjoining acceleration portion the gasification medium is constantly accelerated and upon exit from the nozzle orifice is concentrated in a focus.
