Preparation and Characterization of Solid Biomass Fuel from Waste Mushroom Cultivation Bags
This study investigated the feasibility of preparing the solid biomass fuel from bio-waste material in the waste mushroom cultivation bag (WMCB) and examined whether the decaying carbohydrates due to the fungi present in the bio-waste material of WMCB affects the heating value of the solid biomass fuel. This study involves the following steps: (1) drying the bio-waste material of WMCB and the wood dust of Taiwan Acacia (TA); (2) grinding the bio-waste material of WMCB and the wood dust of TA into the powder GPWMCB and GPTA , respectively; (3) characterizing the heating value of the powder of GPWMCB and GPTA ; (4) solidifying the air-dried powder of GPWMCB (or GPTA ) into a biomass briquette BMBWMCB or BMBTA using the piston-in-mold process; (5) charcoalizing the biomass briquette BMBWMCB and BMBTA into the charcoal briquette CBWMCB and CBTA, respectively, using a home-made mechanical furnace of charcoalization; and (6) characterizing the charcoal yield, the ash and the heating value of the CBWMCB and CBTA , respectively. Both CBTA and CBWMCB inhere the linear relationship between the average heating value and the charcoalization temperature. The RPHV,which indicates the reduction percentage of heating value of CBWMCB,is less than 10%,compared with the heating value of CBTA .
