Abstract:
In a motorized coal stoker including a coal feed hopper with a lower forward passage, a base box forming an ash pit, a rearward ramp adapted to receive coal from the bottom of the hopper, and a pusher assembly disposed in the lower forward passage, eccentric movement means operably connected to the pusher assembly for causing reciprocating action, and a forward stationary planar fire grate for receiving particulate coal incrementally from the pusher means, the improvement comprising:a) aligning the stationary planar fire grate component between its longitudinal ends, with one end thereof being secured to the rearward ramp, the stationary planar fire grate being in a substantially horizontal configuration, which serves to enhance the degree of coal combustion as coal incrementally translates across the fire grate components; and b) wherein the substantially horizontal fire grate has a multiplicity of perforations and which grate forms the top segment of the base box, and which box receives an adjustable supply of forced air flowing therethrough into the grate perforations.
