ABSTRACT:
A Rotary thermal processor for particulate materials has a rotating drum and a rotating hollow auger. A stationary cylindrical oven with stationary coils surrounds the rotating drum. Hot gas heats a first part of the oven, coil and drum. A rotating hollow auger is heated with hot fluid from the coils. Oven exhaust sweeps evaporated and volatized components of the treated materials to separators and a thermal oxidizer. Cleaned gas from the thermal oxidizer heats a second part of the oven coil and drum and exits a stack. The rotating drum and auger lifts and turns the treated material as it is advanced by the auger.
