PLANT FOR PRODUCTION OF PYROLYSIS FUEL Russian patent published in 2016 - IPC C10B49/10 C10G9/32 

FIELD: fuel.

SUBSTANCE: invention relates to low-temperature fast pyrolysis and can be used for production of fuel from biomass of finely disintegrated wood. Plant contains technologically interconnected storage hopper of raw disperse material (RDM) (25), combustion chamber of circulating fluidized bed (CFB) (26), pyrolysis reactor of CFB (2), cleaning cyclones of the first (7) and the second (8) stages, capacitors of the first (9) and the second (11) stages, gas blower (17) with pressure channel of recirculation gas return, pyrolysis fuel pump (13), water heat exchanger (10) with the first and second feed channels of overcooled pyrolysis gas condensate to capacitors of the first(7) and the second (8) stages, pyrolysis fuel cleaning unit (18) with impurities discharge channel (19) connected to pyrolysis fuel pump (13) and a unit for pyrolysis fuel stabilization (20) with pyrolysis fuel discharge channel (24), RDM precombustion chamber (1) with internal channel (22) for supply of heated RDM in pyrolysis reactor CFB (2) and TIV precombustion chamber (21) with internal channel (23) flow of heated TIV in pyrolysis reactor CFB (2). In the combustion chamber CFB (3) are arranged precombustion chamber (1), precombustion chamber (21) and is fitted concentrically pyrolysis reactor (2) of CFB. RDM storage hopper (25) is designed for resultant vapor removal from the hopper zone. RDM precombustion chamber (1) is configured to remove residual moisture from RDM particles by thermal shock. Channel (27) for RDM particles supply is connected with RDM precombustion chamber (1).

EFFECT: higher efficiency of using carbonaceous substance combustion heat.
