ABSTRACT:
A coal feed system for use in a fluidized bed in which a grate is supported in a housing and is adapted to receive, on its upper surface, a bed of particulate material including a combustible fuel. Air is passed through the grate and into the bed to fluidize the particulate material. The particulate fuel material is separated externally of the bed into a relatively coarse material which is distributed over the upper surface of the bed and a relatively fine material which is distributed into the bed below the upper surface.
