Abstract
An improved method for feeding caking coal particles to a fluidized bed gasifier, without prior pretreatment, is disclosed. The coal particles are entrained in a gaseous stream and injected directly into the bottom of the fluidized bed around the outer perimeter thereof at a plurality of points and at a predetermined high velocity, such that the coal particles are shock heated and charred.
