Abstract: 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.

Abstract: Provided is a biomass pyrolysis apparatus comprising: a combustion furnace that produces a heat quantity by causing a stable property fuel to combust; a pyrolysis gasification furnace that produces a torrefied material, and a pyrolysis gas by pyrolyzing woody biomass by a heat quantity produced by the combustion furnace; and a pyrolysis gas introduction passage that introduces the pyrolysis gas from the pyrolysis gasification furnace into a boiler, into which the torrefied material is introduced.

Abstract: 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.

Abstract: The present invention provides a heat treatment apparatus which can increase in size without leading to a decrease in heat transfer performance. The heat treatment apparatus performs heat treatment of treatment objects inside a cylindrical body by heating the cylindrical body rotating around an axis, and the heat treatment apparatus includes a pair of movable support parts provided on both ends side along the axis of the cylindrical body so as to be able to move along the axis and rotatably supporting 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 supporting the cylindrical body around the axis, wherein the cylindrical body is supported by a three-point support of the pair of the movable support parts and the fixed support part.

Abstract: A method of incinerating wastes while controlling the production of dioxins wherein water vapor or water is sprayed in the main combustion zone of an incinerator. An apparatus for practicing the method of waste incineration, including a line for supplying main combustion air, either alone or together with a line for supplying recycled combustion gas, to the incinerator from below its hearth, is provided with a line for supplying water vapor or water in communication with the line or lines.
