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 1,200 and 1,900 degrees. The fuel is gasified by pneumatic metering of pulverized fuel, gasification reaction in a reactor with cooled reactor chamber contour, quencher cooling, crude gas scrubbing, and partial condensation.
