Abstract

An apparatus for gasifying solid fuels such as coal, in a packed bed by a treatment with a gasifying agent such as free oxygen-containing gas and water vapor under pressure, comprising a water-cooled reactor housing provided in its lower portion with gasifying agent inlet openings, a fuel distributor mounted on a vertical axis, a stirrer on a shaft disposed in the fuel bed in the upper portion of the reactor, and independent first and second drive means for independently rotating the fuel distributor and stirrer. Advantageously the distributor includes a hollow bearing shaft coaxial with the shaft of the stirrer and the stirrer shaft also has a bearing, a common bearing support cooperating with both of the bearings.
