A carbide producing method for carbonizing a woody biomass to produce a carbide includes a pyrolysis process in which the woody biomass is pyrolyzed and carbonized, an LHV calculating process in which an LHV of the carbide which is a carbonized woody biomass is calculated, and a supplied heat amount control process in which an amount of heat supplied per unit time to the woody biomass in the pyrolysis process on the basis of the calculated LHV is controlled.

Carbide producing method and carbide producing device

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

This method for inhibiting the occurrence of a pyrolysis deposit in a pyrolysis gasification system includes: gasifying biomass (S) through pyrolysis in a pyrolysis gasification furnace (); separating, in a solid-gas separation unit (), a pyrolysis gas (G) and a carbide (C) continuously formed through pyrolysis of the biomass (S); feeding an oxygen-containing gas (G) to the separated pyrolysis gas (G); and introducing the pyrolysis gas (G) together with the oxygen-containing gas (G) to a combustion furnace () through a pipe () which constitutes a pyrolysis gas line ().

Method for inhibiting occurrence of pyrolysis deposit in pyrolysis gasification system, and pyrolysis gasification system

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.

Biomass pyrolysis apparatus, and power generation system

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.
