ABSTRACT:
An inclined hearth incinerator for the incineration of municipal, and industrial/commercial solid waste optionally in conjunction with sludge, with a controlled amount of combustion air allows the even distribution of underfire air to an upper hearth of plural stepped hearths in the floor of the incinerator. A clean-out assembly includes a piston which automatically cleans out feed-tubes for combustion air. The feed-tubes are protected by being embedded in the hearth, or being disposed beneath the hearth. The piston and a ram on the hearth may be interconnected for reciprocation by an actuating means so as to provide synchronous to-and-fro movement of the piston and ram.
