ABSTRACT:
A single reactor is used for gasifying solid fuels of a wide range of particle sizes without first comminuting the particles to a common size. The larger particles are gasified on a fixed bed, and the smaller ones are gasified on a fluidized bed. In the reactor, the fluidized bed is arranged above the fixed bed and gases rising from the fixed bed help to fluidize the fluidized bed. In addition, a dust gasification region can be provided above the fluidized bed.
