Provided is an externally heated carbonization furnace that includes a plurality of rotary kilns connected in series, each of which includes an outer cylinder, a kiln inner cylinder that rotate relative to the outer cylinder, and a heater that supplies heating gas to a section between the outer cylinder and the kiln inner cylinder. The externally heated carbonization furnace further includes a drive device that rotates at least one of the kiln inner cylinders and the kiln inner cylinder different from the at least one of the kiln inner cylinders and a control device that controls the drive device according to moisture content of a treated object in the kiln inner cylinder.

Externally heated carbonization furnace

A heat treatment apparatus for performing heat treatment of treatment objects inside a cylindrical body by heating the cylindrical body and rotating the cylindrical body around an axis, includes a pair of movable support parts provided on opposite ends of the cylindrical body along the axis of the cylindrical body so as to be able to move along the axis and rotatably support the cylindrical body around the axis, and a fixed support part provided between the pair of the movable support parts along the axis so as to be unable to move along the axis and rotatably support the cylindrical body around the axis. The cylindrical body is supported by a three-point support of the pair by the movable support parts and the fixed support part.
