Gasification method and device for producing synthesis gases by partial oxidation of fuels containing ash at elevated pressure and with quench-cooling of the crude gas

Abstract From the Canadian patent

A method 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 method which includes the principle process steps of pneumatic metering of pulverized fuel gasification reaction in a reactor with cooled reactor chamber contour quencher cooling, crude gas scrubbing, and partial condensation includes the specific steps of: feeding a pulverized fuel with a water content of < 10 wt.% preferably < 2 wt.%, and a grain size of < 200 µm preferably 100 µm, to a …
