An automatic coal stoker is disclosed having at the base of its hopper an enclosed reciprocating pusher assembly rectangular box shaped which delivers compressingly a defined but variable quantity of coal into a restricted passageway. Successive quantities form a compressed strip of coal to be burned between side rails of a fire grate situate and over an air box fed with a forced air supply. As the strip works its across the substantially horizontal grate, it burns without forming clinkers, discharges ashes at the bottom of the incline, and effects a minimal degree of uncombusted coal in the ashes. The fire grate of the present invention is substantially horizontal throughout its functional length.
