Waste-burning furnace
The furnace includes an upstanding hopper-like member having an increasing cross-sectional area from a fuel inlet at its upper end to a hollow box-like grate releasably and removably mounted within its lower end portion at an elevation slightly below the upper extremity of a gas passageway opening laterally from such member and communicating with a manifold chamber extending horizontally therefrom. The grate has elongate slot-like openings extending horizontally of and vertically through its medial portion, and preferably includes cylindrical solid rods extending longitudinally of the upper portions of such openings. An electrically-powered blower is releasably connected to the grate, for movement therewith, and during operation conducts air to the interior of the hollow sections of the grate. The latter are provided with apertures which discharge jets of air vertically upward and downward, and also angularly upward and downward, from the grate. The angularly directed air jets include ones that emanate from the upper edges of the grate openings and are directed toward the centers of such openings, and others that are discharged from grate edges that are closely adjacent the gas passageway and are directed toward such passageway. Normally shut closure members are provided in association with the fuel inlet at the upper end of the hopper-like member and in association with an ash-removal passageway provided within the lower end portion of such member. Gaseous combustion products introduced into the manifold chamber pass therefrom through ducts communicating therewith on opposite sides of a vertical baffle extending centrally and longitudinally of the chamber.
