PLANT FOR THERMAL PROCESSING OF SOLID FUELS Russian patent published in 2014 - IPC C10B53/00 

FIELD: process engineering.

SUBSTANCE: invention relates to chemical industry and can be used in processing of coal shale and peat. Proposed plant comprises bin (1) with fuel and equipped with feeder (2), fuel mixer (3) and solid heat carrier cyclone (4), drum-type pyrolysis reactor (5) with horizontal shaft, dust separation chamber (6) with dust separation cyclone (9). Outlet of cyclone (9) is connected with compartment (10) of fluid condensation from vapour-gas mix. Bottom of dust separation chamber (6) is connected with inlet of flash firebox (8) its outlet being connected via gas-dust flow splitter (11) with cyclone (4), its ash discharge outlet being connected with fuel and solid heat carrier mixer (3). Outlet of flash firebox (8) is connected with ash separator (12), its ash discharge being connected with ash heat exchange (13) while gas pipe being connected to waste-heat boiler (15). Dust separation chamber (6) is furnished with flow splitter plate (17). One part of plate (17) is arranged in outlet pipe (18) of pyrolysis reactor (5) above solid material layer at the angle of its natural slope. Second part of said plate (17) is arranged in dust separation chamber (6) horizontally to cover is cross-section with slot formation.

EFFECT: higher quality of fluids, simplified dust separation and condensation.
