Abstract

A method and device for the gasification of solid fuels such as bituminous coal, lignite coal, and petroleum coke in the flue stream, with an oxidizing medium containing free oxygen by partial oxidation at pressures between atmospheric pressure and 80 bar, and at temperatures between 1200 and 1900° C., consisting of the process steps of pneumatic metering for pulverized fuel, gasification in a flue stream reactor with cooled reaction chamber contour, partial quenching, cooling, crude gas scrubbing, and partial condensation.
