Abstract
A reactor for the continuous gasification of coal under superatmospheric pressures and elevated temperatures with gaseous gasifying agents containing free oxygen and with oxygen-free gasifying agents such as steam and/or carbon dioxide is disclosed. The reactor includes a substantially conical rotary grate which is rotatably mounted in the lower portion of the reactor housing. The rotary grate feeds the gasifying agent and/or discharges the gasification residues. Notwithstanding the inside diameter of the reactor housing, the clearance a between the rotary grate and the housing is 100-200 millimeters, the height b of the annular rim of the rotary grate is 100-350 millimeters, and the vertical distance c from the rotary grate to the housing bottom is 100-350 millimeters.
