Horgan, J J

A coal fired combustor for a gas turbine engine comprises a centrifugal fluidized bed where the coal particulate is introduced radially inwardly toward the axis of rotation through the bed. A centrally mounted pipe which may be rotatable at a different velocity collects and distributes the gases generated by the combustion process and also serves to filter out the elutriated particles. Additives to the fuel for minimizing sulfur dioxide (SO/sub x/) and nitrogen oxide (NO/sub x/) may be added to the fuel prior to introduction to the bed so that the adverse effects of elutriation does not occur before sulfur adsorption.
