Abstract

An apparatus for carrying out a fluidized bed process comprises a lower flared portion 3, Fig. 1, forming an intake for a part of the fluidizing medium, the upper part of the flared portion being spaced from the walls of the main part of the apparatus, the space being bridged <PICT:0834455/III/1> <PICT:0834455/III/2> by a grate 6 which slopes from the walls downwardly towards the flared portion. The grate may be formed by radial or concentric members having overlapping portions, so that fine particles are prevented from passing into the chamber 7. The fluidizing medium which enters through pipe 5 may have a different ratio of air to steam oxygen to steam or oxygen to carbon dioxide from that which is passed through line 2. A Venturi 4 may be interposed between line 2 and flared portion 3. Gas passing from the chamber 8 may be passed through pipe 21, Fig. 4, into a cyclone separator 50, the clean gas passing out through pipe 22 whilst the dust falls down tube 23. An inert gas or gas manufactured in the apparatus and extracted by compressor 25 after cooling, is fed at 24 into tube 23 to maintain the dust in a slightly fluidized state. After passing through valve 26 into chamber 27, the dust meets gasifying agents arriving through tube 28. These carry the dust through tube 29, 2a back into the chamber 8. The apparatus may be used for the production of hydrogen from producer gas containing steam by reduction with iron which may be produced by reducing iron oxide with producer gas. Specification 723,332, Swiss Specifications 292,727, 292,859, and French Specification 1,050,572 are referred to.
