FIELD: process engineering.SUBSTANCE: invention relates to thermal treatment of biomass. Particularly, it relates to the process including feed of biomass (6) into reactor (16). Biomass (6) is heated in said reactor to 180-350°C at low oxygen concentration. Here, components are produced that feature inertia relative to biological decomposition with formation of gaseous reaction products (10) and heat-treated biomass (8). Reaction gaseous products (10) are fed for combustion (13) while hot flue gases (11) of said combustion (13) are fed into reactor (16) for thermal treatment process. Combustion process (13) is executed in boiler (14) that combusts extra fuel (15) in amount not over 20%, preferably, not over 10% of the fuel energy equivalent are obtained from reaction gaseous products (10) in reactor (16). Biomass is heat treated in continuous action reactor 16 while flue gas flow flows in the same direction with biomass flow in reactor (16).EFFECT: better fuel efficiency of biomass.8 cl, 3 dwg |
