MULTITUBULAR DEVICE FOR COAL DECOMPOSITION WITH EXTERNAL HEATING Russian patent published in 2014 - IPC C10B47/00 C10B57/00 F27B9/06 F27B9/14 

FIELD: process engineering.

SUBSTANCE: invention can be used for coal processing to high-quality fuel. Proposed device comprises airtight furnace body (1) with channel (4) for coal displacement and decomposition. Said channel (4) has coal inlet (2), coal outlet (3) and coal decomposition gas collector tube (14). Said channel (4) is connected with auxiliary rotary device (6) arranged outside the furnace body (1). Heat transfer chamber (5) is composed between said channel (4) and furnace body (1) inner wall. Note also that this chamber is collected with high-temperature gas heating device and comprises heated gas outlet (12) for preheating of material via tubes. Aforesaid channel (4) is composed of multiple closely located parallel pipes. One end of the channel comprises feed compartment (11) for communication with coal inlet (2) while opposite end comprises discharge compartment (13) for communication with coal discharge opening (3).

EFFECT: high-quality coal and decomposition gas, efficient use of power and coal.
