The invention comprises a drying and sorting apparatus which is integrated with a conventional steam generator for separating organically derived solid fuel from solid inert materials and for removal of moisture from the solid fuel prior to feeding such fuel to a combustor. Low level heat in the steam generator combustion gases, after heat exchange with the steam generator fluid circuits, provides the means for removing moisture from the solid fuel when hot air/gas (unsaturated with respect to moisture) is passed through a bed containing a mixture of solid fuel and waste inert material particles, fluidizing them. When in a fluidized state the lighter organically derived solid fuel particles separate from the heavier inert material particles. The hot air/gas is admitted to the bed directionally in a manner which drives the waste inert material along the bed surface and solid fuels rise above the surface, each traveling to separate removal points from the bed after a period of retention which facilitates separation. A cyclone can be installed at the outlet of the bed vessel for removal of solid particles entrained in the hot air/gas stream.
