In a process and apparatus for the production of gas containing hydrogen and carbon monoxide from a solid fuel in a fluidized bed, the solid particles contained in the product gas are separated off in a cyclone separator and recycled to the fluidized bed by way of a recycling conduit. The recycling conduit is provided with injection nozzles for introducing gas flows into the recycling conduit in a pulse-like manner in order to loosen up the particles therein. The gas flows may be introduced into the recycling conduit in displaced relationship in respect of time in such a way that, of two adjacent injection locations, gas is injected through the injection location which is arranged at a greater spacing from the reactor at a later time than at the injector location which is closer to the reactor.

Process for the production of gas containing hydrogen and carbon

A lining for a furnace chamber which is at least approximately round in cross-section is divided into at least two layers in a radial direction and into at least two portions in an axial direction. A gas seal is disposed between the lining portions, the gas seal being in the form of a foil as of metal and being divided in a radial direction into at least two portions releasably connected together in such a manner as to permit the inner portion to be removed in an axial direction. The gas seal can therefore be composed of individual seal portions, in a radial direction, and can be fitted separately.
