FIELD: process engineering.
SUBSTANCE: invention relates to chemical industry and can be used for production of high-energy solid fuel from coal. Device consists of two communicated chambers. First chamber consists of coal feeder (1), fire grate (2) to remove separated ore, device to feed blow air (3) at the temperature not over 400°C and to add flue gas to 100%, waste gas removal system (4) and coal layer transfer pipe (5). Second chamber consists of the device (6) of initial blowing at the temperature not higher than 400°C, device (7) of secondary blowing to afterburning of combustible components for coal thermal decomposition and coke gasification at 600÷1000°C, heat energy recovery system (8), flue gas removal system (9) and coke discharge pipe (10).
EFFECT: more efficient and ecologically safe process.
