FIELD: wood-chemical industry; the methods of large-capacity production of a lump fuel charcoal. ^ SUBSTANCE: the invention is pertaining to the field of wood-chemical industry, in particular, to the technologies for a charcoal-burning of a wood raw material based on the methods of a temperature-average pyrolysis. The method includes: operations providing for receptions of the middle-sized raw materials from a warehouse; transportation of the raw materials from the warehouse into some of the similar type module chambers of a periodical charcoal-burning action; a multi-stage process of a charcoal-burning in each charcoal-burning module chamber at the air pressure close to atmospheric. The process of the charcoal-burning includes: a sequential drying of the raw material by a superheated steam, including its mixtures with the air; the raw material temperature-average pyrolysis, calcination and chilling of the coal; its discharge from the charcoal-burning module chamber. At that the phase of the pyrolysis is divided into two parts - an endothermic part and an exothermal part. All operations are conducted in the automatic mode. The heat-carrying agents and electrical power for realization of the processes of drying, pyrolysis, calcination and granulation are fed from the all-station power-generating unit. The gained generator gas after chilling and cleanout is used as a gaseous fuel in a gas-diesel engine and in the second power-generating unit, in which all the non-condensable gases of the pyrolysis are burnt up. The invention also is pertaining to the device for realization of the method. The invention ensures production of the granular charcoal at the small capital inputs. ^ EFFECT: the invention ensures production of the granular charcoal at the small capital inputs. ^ 5 cl, 1 tbl, 1 dwg |
