Abstract:
In a motorized coal stoker housing 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 fire grate for receiving particulate coal incrementally from the pusher means, the improvements comprising:(a) the stove housing further comprising a larger and forward first chamber and a hermetically sealed smaller and rearward second chamber; (b) the first chamber having closed sidewalls, a closed top wall, a front facing vertical panel perforated for intermittent user access, and a vertical inner back wall adapted to receive a coal stoker and coal firebox assembly; (c) an exit portal means proximal the housing back wall and within the second chamber adapted to conduct coal combustion gases from the first chamber to: (i) a first conduit means disposed in the second chamber and operatively interconnecting between the exit portal means and a flue conduit for cooled combustion gases, said first conduit means comprises a first pair of opposing tubular members separately connecting at the lower ends thereof with the exit portal means and jointly connecting the upper ends thereof with a first manifold located in the upper section of the second chamber, said first manifold being functionally connected to the flue conduit, such that venting combustion gases are precluded from leaking into the second chamber; and, (ii) a first blower means adapted to introduce forced air flow proximal to the bottom of the second chamber and to allow flow therethrough, so as to vent heated forced air proximal the upper and forward end of the second chamber and therefrom outwardly into the ambient surroundings.
