摘要： 以山核桃、油茶和板栗3类果蓬为原料,研究了此类原料与杉木、松木屑在不同配比条件下对果蓬类致密成型特征及其机制炭质量的影响。证实了果蓬类原料因纤维素含量、木质素含量与杉木、松木存在差异,且因较高的灰分含量限制,需与杉木或松木屑等原料在一定配比条件下才可实现良好的致密成型。而配比选择试验结果则表明,果蓬原料与杉木、松木屑混合原料以3:7比例配料为宜;在此条件下,制备的机制炭外形平直无裂缝,得率为 33.85%~36.73%,固定碳含量 79.80%~86.20%,热值28.96~31.92 MJ/kg。

Abstract: In this research, briquette and briquetted charcoal were made by use of epiear of Carya cathayensis, Camellia oleifera, Chestnut and sawdust of pine and China fir. The character of densification and molding, and the quality of briquetted charcoal made by different proportions of epiear and sawdust were studied. The result indicated that cellulose and lignin content were different between epiear and sawdust of pine and China fir. Because ash contents of epiear were high, the raw stuff of briquette which has good characteristics of densification and molding must be mixed by epiear and sawdust of pine and China fir at a regular ratio. This paper also tested briquetted charcoal made by different ratio of epiear and sawdust. The result showed that the optimal ratio of epiear and sawdust was 3:7. In this condition, the briquetted charcoal has flat shape and no cracks. The yield of carbonization was 33.85%-36.73%, and the fixed carbon and combustion values of briquetted charcoal were 79.80%-86.20% and 28.96-31.92 MJ/kg, respectively.
