Abstract:
An improved grate for the efficient burning of solid fuel and for forcing heated air therethrough and out therefrom, said grate comprisinga plurality of substantially parallel, first tubular members defining a first generally planar surface for supporting the lower surface of solid fuel, each of said first tubular members having an open end and a closed end, a plurality of interior tubular members, supported within and in axial alignment with said first tubular members, each of said interior tubular members being open at both ends and having a first open end for receiving air from within said first support member and a second open end for transferring air out of said grate, a plurality of substantially parallel second support members defining a second generally planar support surface located below said first surface, said second support members being located between alternate ones of said first support members and defining, in combination with said first support members, a plurality of troughs for supporting glowing coals, a multiplicity of orifices extending through each of said first support members, each orifice being directed toward said first planar surface for creating a zone of turbulence in one of said troughs beneath the lower surface of the solid fuel, a blower connected to said first tubular members for moving air into said open ends of said first tubular members, through said orifices and through said interior tubular members.
