| 摘要 |
FIELD: energy; biotechnology.SUBSTANCE: invention can be used for production of environmentally friendly energy through biomass combustion. Biomass processing includes loading of biomass in torrefication system, heating of biomass containing moisture till torrefication temperature. Torrefication system (1) comprises first processing device (3) and second processing device (18). In first device (3) biomass is heated up to 260-310 °C during first period of time and supplied to second processing device (18) at temperature of 230-280 °C during second period of time which is longer than first period of time. Herewith, temperature in second device (18) is kept lower than the highest temperature in first device (3). First period of time is preferably maximum 3 min, and second period of time is minimum 3 min.EFFECT: invention provides improved, energy-saving technology of processing biomass to produce fuel with especially useful properties - high calorific capacity and improved dispersibility.17 cl, 5 dwg |
