Hamilton, S; Horgan, J J

An increase in the temperature of the gaseous working medium in a gas turbine engine fueled with coal-fired gasifier having a rotating fluidized bed, where the coal is fed radially inwardly through the bed toward the axis of rotation is obtained by including a secondary combustor. The gasifier is fed with compressor discharge air and is operated fuel rich by limiting the amount of compressor discharge air fed to the fluidized bed. The excess compressor discharge air mixes with the exhaust from the gasifier for further combustion resulting in an increase in the temperature of the gaseous working medium that is ultimately utilized for driving the turbine of the engine.
