Abstract: FIELD: machine building. 
     SUBSTANCE: installation for multi-phase pyrolysis of organic raw material consists of hopper of source raw material and of equipment successively installed downstream processed raw material, such as: device for processed raw material drying, reactor of pyrolysis and device of semi-coke cooling with inlets and outlets for gas and solid phases correspondingly. The installation further has a pyro-gas outlet line and a heating furnace including inlets and outlets for fuel and heated medium correspondingly. The installation is equipped with a device preparing pyrolysis process equipped with inlets and outlets for solid phases and gas correspondingly and with a heat exchanger. Also, the inlet for solid phase of the said device is coupled with the outlet for solid phase of the device for processed raw material cooling. The outlet of the said device for solid phase is connected with a corresponding inlet of the pyrolysis reactor; the gas outlet of the said device is connected with the inlet on a heating side of the heat exchanger. The outlet on the heating side of the heat exchanger is connected to the gas inlet of the device for semi-coke cooling via a gas blower. Further, the installation is equipped with two additional heat exchangers and an injector. The inlet on the heating side of the first additional heat exchanger is connected with the gas outlet of the pyrolysis reactor, while the outlet on the heating side of the said heat exchanger is connected with the inlet on the injecting side of the injector. The inlet on the injecting side is connected to the gas outlet of the semi-coke cooling device via the gas blower. The injector outlet is connected to the inlet on the heating side of the second additional heat exchanger. The outlet on the heating side of this heat exchanger is connected with the pyro-gas outlet line via the gas blower. This line is coupled with a heating furnace and with the inlet on the heating side of the first additional heat exchanger. The outlet on the heating side of this heat exchanger is connected with the gas inlet of the device for pyrolysis preparation. Also, the gas inlet of the device for raw material drying is connected with the inlet on the heating side of the second additional heat exchanger via the gas blower; the outlet of this heat exchanger on the heating side is coupled with the heating furnace. The outlet of heated pyro-gas of the heating furnace is connected with the gas inlet of the pyrolysis reactor. Notably, the installation is equipped with a steam-turbine facility connected to the heating furnace. Additionally, the installation is furnished with a solid fuel boiler the solid phase inlet of which is connected to the outlet for solid phase of the semi-coke cooling device. 
     EFFECT: raised efficiency of installation in whole, simplification of design, increased repair ability, reduced heat loads on separate units of installation, reduced specific power and material expenditures and expanded functionality.
