摘    要:该文采用能值方法对北京郊区生物质大中型秸秆气化站和沼气站的能值投入及产出进行了核算,结果表明,大中型秸秆气化站和沼气站净能值产出率(EYR)均小于1,秸秆气化站净能值产出率为0.55,沼气站净能值产出率为0.70,说明此2种能源经济生产方式效率低,不具备经济活动竞争力。因受到技术水平制约,这2种能源开发方式为经济不合算开发方式,对其开发利用尤其是大中型沼气站的开发利用应有清醒认识,因地制宜地建设并加大技术研发力度;同时要注重其公益性特征,充分挖掘北京郊区生物质资源开发潜力。

关 键 词:秸秆气化,沼气,生物质,净能值产出率

Abstract:Based on emergy method, the paper evaluated emergy input and output of middle straw gasification stations and biogas stations in Beijing suburb. The results showed that the net emergy yield ratio of straw gasification was higher than that of biogas station, and they were both lower than 1, which indicated that they both had a lower efficiency and no stronger economic competitiveness. So the development mode of two kinds of energy was uneconomical and unreasonable due to technical restriction. We should have a better understanding of the development mode of biomass energy, especially the development mode of the big or middle biogas stations. It should be constructed suitably according to the local conditions and lay emphasis upon the enhancement in research, meanwhile, it should also lay emphasis upon the commonweal characteristic of the bio-energy and exploit adequately the potential of biomass resources in Beijing suburb.
Keywords:straw gasification  biogas  biomass  net energy yield ratio
