Study on the preparation of new biomass fuel based on fungus chaff of Auricularia auricula

Abstract After saturated steam pretreatment and thermo-pressure drying, the moisture content decreased and the calorific value increased, thus the waste fungus chaff was transformed into new biomass energy. The physicochemical properties of the fungus chaff after thermo-pressure drying were tested to meet the standard of being used as biomass fuel. The experiment showed that: The thermo-pressure drying technology can stably reduce the moisture content of the fungus bran from more than 55% to less than 35%, and increase the received base calorific value from 4763.9kJ/kg to 12213.8kJ/kg, which meets the requirements of biomass power plants. The performance of volatiles, slagging property and other related fuels is improved, which lays an experimental foundation for the industrial implementation of biomass fuel.
