METHOD OF ACTIVATING FRACTIONATED BY SIZE COAL PARTICLES (VERSIONS) Russian patent published in 2013 - IPC C01B31/10 C10B1/00 F23C1/12 F27B7/00 

FIELD: chemistry.

SUBSTANCE: invention relates to field of industrial heat-and-power engineering and can be applied in obtaining activated coal. Method of activating fractionated by size coal particles is realised by their continuous re-pouring and interaction with countercurrent torch in inclined relative to horizontal plane reactor with heating, separation and burning of volatile substances, formation and output from reactor of mixture of volatile substances and products of burning, further re-pouring and cooling by countercurrent flow of products of burning in inclined relative to horizontal plane cooler and after-burning volatile substances and release of products of burning into atmosphere. Processes of activation and cooling are realised in reactor and cooler of drum type and/or chamber type with mechanised grate. Torch is formed by separately introduced jets of gas, air, steam and products of burning, with steam, being obtained in boiler-utiliser in the process of after-burning of mixture of volatile substances, products of burning are output from cooler, and products of burning from boiler-utiliser are supplied into cooler.

EFFECT: invention ensures reduction of heat loss and gas consumption.
