ABSTRACT:
A process and apparatus for the continuous gasification of fuels, which are mainly in lump form. The fuels are subjected to a superatmospheric pressure in a fixed bed treatment with a gasifying agent consisting of gases which contain free oxygen and water vapor and/or carbon dioxide in a water-cooled reactor housing. The housing contains a substantially conical rotary grate, which is rotatably mounted in the lower portion of the reactor housing and serves to discharge the gasifying agent into the reactor shaft and permits the removal of gasification residue from the shaft. The gasifying agent is positively distributed in correspondence with the quantity of fuel, which increases in the radial direction of the shaft resulting in an approximately uniform time of contact between the gas and fuel across the entire shaft area.
