农作物固体废弃物致密成型燃料能量学对比分析（Comparative Analysis on Energetics of Agro-residues Densification Briquetting Fuel）
农作物固体废弃物 致密成型 燃料 能量学
2009/11/3
选取主要农作物固体废弃物为研究对象，综合考虑其热力学特性以及成型设备工程技术参数，对农作物的固体废弃物致密成型燃料与煤的能量学进行了比较研究。结果表明，对于秸秆类的固体废弃物致密成型燃料，由于其生产耗能高，仅当煤从生产地到使用地之间的输送距离超过4000 km时，此类固体废弃物致密成型燃料与煤具有近似同等的能量竞争力；而对于果壳类的固体废弃物致密成型燃料，其生产耗能较低，临界输送距离较短。当煤从生...
