Abstract

A fixed-bed coal gasifier includes an upright cylindrical wall providing a fixed-bed coal gasification chamber for gasifying coal to produce synthesis gas, with an end-piece closing off the upper end of the cylindrical wall. A coal inlet opening is provided in the end-piece, and a gas outlet leads from the chamber at a high level. A gas collection device is provided within the gasification chamber below the inlet opening, and provides a central gas collection zone operatively connected to the gas outlet of the gasification chamber so that synthesis gas produced in the chamber can pass from the gas collection zone to the gas outlet. The device is spaced with clearance from the cylindrical wall so that coal can pass through the gap between the device and the cylindrical wall. A plurality of horizontally spaced coal distribution means, for distributing coal from an upper zone above the gas collection device into a lower zone immediately below the gas collecting device, are also provided.
