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 an inclined fire grate situate over an air box fed with a forced air supply. As the strip works its way down the inclined grate it burns without forming clinkers and discharges ashes at the bottom of the incline.
