ABSTRACT:
Bales of combustible trash made to specific specifications are burned in a furnace having two parallel upright sidewalls between which the bales pass during burning. A horizontal grate extends between the sidewalls. The bales, if remotely made from the furnace, are bound by an easily meltable strap. The length of the bale is measurably smaller than the distance between said sidewalls to accurately accommodate springback. A ram, after compacting the waste in segmental fashion, pushes each bale to a position between said sidewalls; with the length of the bale being perpendicular to the sidewalls, so that a bale enters the furnace. Springback following the melting of straps allows the bale to expand to fill the gap between the sidewalls. This facilitates ignition and/or burning of the bales and provides a seal against furnace sidewalls. When the ram feeds a fresh bale, previously charged bales (consumed proportional to time in the furnace) are advanced toward the ash discharge port. Before the bales are formed, the trash may be optionally dried by using heated air in the classification into "light" sort and "heavy" sort. The "light" sort is baled and burned as described above. The "heavy" sort or a part of the light sort may be premixed with noxious liquid or solid wastes before charging to the furnace. Temperatures consistent with economical use of refractory (1500.degree. F. to 1700.degree. F.) are maintained, for a limited area adjacent the inner wall of the furnace, by addition of liquid water, while interior temperatures of the furnace of about 3000.degree. F. prevail in the central portion of the furnace necessary for the incineration of noxious wastes.
