摘要
文章以芦苇杆和芦苇杆生物炭为原材料开展了制备高热值生物质可燃颗粒的研究,并测试了其物理性能、热学性能和防潮性能。研究结果表明:当生物炭质量分数为0~50%时,可燃颗粒的密度为1188~1304kg/m^(3)、高位热值为16.75~22.00 MJ/kg、燃烧速率为3.70%/min~3.24%/min、燃烧后残余率为5.33%~7.05%、单位体积热值为19905.43~28698.51 MJ/m^(3)、吸湿率为17.44%~13.66%;当生物炭质量分数为20%时,生物质可燃颗粒的综合性能最优,此时其密度为1281 kg/m^(3)、高位热值为18.79 MJ/kg、燃烧速率为3.50%/min、燃烧后残余率为5.97%、单位体积热值为24075.11 MJ/m^(3)、吸湿率为14.96%。
To explore the performance of producing high calorific value combustible pellets from reed stalks,feasibility work was conducted to prepare Biomass pellet fuel using reed stalks biochar and reed stalks as raw materials.Their physical properties,thermal properties,and moisture resistance were also tested.The results show that when the mass content of biochar is 0~50%,the density of combustible pellets ranges from 1188~1304 kg/m^(3),the high heating value is 16.75~22.00 MJ/kg,the combustion rate is 3.70%/min~3.24%/min,the residual rate after combustion is 5.33%~7.05%,the calorific value per unit volume is 19905.43~28698.51 MJ/m^(3),and the moisture absorption rate is 17.44%~13.66%.When the mass content of biochar is 20%,the comprehensive performance of biomass pellet fuel is the best:the density is 1281 kg/m^(3),the high heating value is 18.79 MJ/kg,the combustion rate is 3.50%/min,the residual rate after combustion is 5.97%,the calorific value per unit volume is 24075.11 MJ/m^(3),and the moisture absorption rate is 14.96%.
