Abstract
A method for drying biomass fuel using waste heat of flue gas from a power plant. The method includes: 1) stepwise recovering, by multi-stage condensation, sensible heat of flue gas; stepwise heating air using the sensible heat, to yield first-stage dry air and second-stage dry air; 2) convectively drying and dehydrating biomass fuel using the first-stage dry air having a temperature of between 150 and 180° C.; 3) further convectively drying and dehydrating the biomass fuel using the second-stage dry air having a temperature of between 80 and 100° C.; and 4) drying and dehydrating the biomass fuel using the third-stage dry air having a temperature of less than or equal to 25° C.
