【摘要】 分析了环模孔长径比、林业剩余物的粒度、含水率和进料转速对颗粒燃料成型的影响,并找出了杉木、松木、樟木、杂灌、锯末、竹屑6种林业剩余物的颗粒燃料较佳成型工艺条件。检测结果显示,生产的林业剩余物颗粒燃料的密度在1.1 g/cm3以上,以杉木和松木为原料的颗粒燃料的热值最高,超过17 800 kJ/kg。更多还原

【Abstract】 In this study,the influence of length-to-diameter ratio of ring die,particle size and moisture content of forest residues and feed rate on the pelletisation was analyzed. The optimal processes to prepare pellet biofuel using fir,pine,camphorwood,miscellaneous shrubs,sawdust and bamboo chips were explored. Test results showed that the average density of the pellets were above 1. 1 g / cm3. Pellets made from fir and pine wood exhibited the highest caloric values of above 17 800 kJ / kg.更多还原
