Method for gasification of coal or carbonaceous materials in fluidized bed gasification reactor, involves carrying out gasification of substances such that dust-laden raw gas and ash particles are drawn off from underside of reactor

摘要

A gasifying agent containing a mixture of carbon dioxide, water vapor, and oxygen is introduced under pressure into the lower portion of reactor, through a feed device (4), such that blown gasification of the substances is carried out in the fluidized bed (6). The gasification of substances is carried out along the rotation axis of a reactor shell (3) which rotates by the ignition of plasma such that the dust-laden raw gas and the ash particles are drawn off from the underside of gasification reactor. An independent claim is included for a fluidized bed gasification reactor.
