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 (SOx) and nitrogen oxide (NOx) 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.
