为了促进诸如林业生物质和修剪的果实的分支等未使用的木质生物质的利用，木质生物质作为煤粉燃烧发电厂的燃料的利用已经引起关注。在林区木质生物质资源的利用过程中，必须研究和降低资源采集、粉碎、干燥等预处理和运输过程中的能耗。研究了半炭化热解对木质生物质粉碎能量的影响，并对木质生物质的输运性能进行了评价。所得结果如下。根据邦德定律，提出了木本和半碳化地区的功指数的经验关联式。用本文的经验关系式估算粉碎能，精度在± 30%以内。为了评价半碳化工艺对降低输送和粉碎能耗的效果，进行了能耗分析。从分析结果可以看出，在相同的输送距离下，质量屈服条件为0.6时的能耗比最小。
In order to promote the utilization of unused woody biomass such as forestry biomass and pruned branch of fruit, the utilization of woody biomass has come to attract attention as a fuel at the pulverized-coal fired power plant. When the woody biomass in the forestry region is utilized, it is necessary to examine and reduce the energy consumption for collecting of resources, preprocessing such as comminuting and drying and transportation . In the present study, effect of semi-carbonization pyrolysis on comminution energy and assessment of transport property of woody biomass is investigated. The results obtained are as follows. Empirical correlations of work index in Bond’s Law are presented for both woody and semi-carbonization regions. The comminution energy can be estimated by the present empirical correlations within an accuracy of ±30 percent. To evaluate the effect of semi-carbonization process on the energy reduction of transport and comminution, an analysis of energy consumptions is conducted. From the result of analysis, it is found that the energy consumption ratio is the minimum at a mass yield condition of 0.6 for the same transport distance.
