ABSTRACT:
A dry coal fuel supply system for a gas turbine engine includes a continuous loop conveyor pump having a plurality of positive displacement pistons connected by a cable and driven by a variable speed motor with respect to an atmospheric reservoir filled with powdered coal and the continuous loop includes a dual stage coal pick-up for assuring coal fill of the conveyor system to accurately meter coal therefrom in accordance with the speed of the variable drive motor for driving the conveyor and wherein the system includes an improved sealed discharge manifold means for directing a controlled amount of the compressor discharge air of the gas turbine engine to a plurality of air jets for blasting high pressure air across the coal pump pistons to direct a fluidized powdered coal mixture into a downstream, closely associated fuel nozzle system for a gas turbine engine combustor.
