| 摘 要： | 以玉米秸秆和水稻秸秆为研究对象,通过测定二者厌氧发酵后的沼气、沼渣产量及热值,探讨秸秆气固燃料二元联产的综合能源利用效率与经济效益。结果表明,由于发酵后秸秆沼渣中木质素含量增大,沼渣热值也有所增大;沼渣成型燃料密度、机械耐久性等特性均优于原秸秆;秸秆气固燃料二元联产综合能源利用效率较秸秆直接燃烧可提高40%~50%(以发电量计);因免除收集、运输和粉碎等成本,秸秆沼渣生产成型燃料的综合成本较秸秆压块单独生产模式可节省46.4%。

| Abstract: | This study takes corn straw and rice straw as the research object. By measuring the yields of biogas and biogas residue,and combining the calorific value analysis,the comprehensive energy utilization efficiency and economic benefit of the dualistic fuel combined production of straw gas solid are discussed. The results showed that the calorific value of biogas residue was increased due to the rise of lignin content,and the fuel density,mechanical durability of the biogas residue also were better than the original straw. The utilization efficiency(power generation)of the gas-solid combined energy utilization of the straw gas was increased by 40%-50% compared with the direct combustion of straw,and the comprehensive production cost of densified fuel produced by biogas digestate is lower than that of using raw straw with a percent of 46.4%. |
