【摘要】 煤炭在我国一次能源结构中将长期占主导地位,同时源于煤燃烧所排放的众多污染物也受到了广泛的重视.考虑可持续发展的需要,本文以能源的生态效率作为评价指标,结合我国的燃料资源情况,在前期研究工作基础上,对燃煤电站生态效率的评价方法及其影响因素进行了进一步的研究,给出了根据燃料性质、电厂效率简捷地评价SO2、NOx及CO2对电站生态效率影响程度的方法,并提出了采取减排措施时相应的指标要求.更多还原

【Abstract】 Coal will be the predominant energy in the futures for China. At the same time, the pollutants originated from coal combustion have accepted the attentions worldwide. In the light of sustainable development requirements, the authors evaluated the coal-fired power palnt (CFP) based on the energy ecological efficiency when the typical coal resources were burned in China. A clear procedure was presented upon the earlier researches with the influences of emissions of SO2, NOx and CO2, the coal properties and the power plant efficiency on the energy eco-efficiency. Of course, the reduction of noxious gases (SO2, NOx and CO2) had positive effects on the energy eco-efficiency and the CFP was quantitatively evaluated with the gaseous pollutants reduction installments. The dependence between CO emission and NOx emission was also simple analyzed for those lower efficiency industrial boilers.更多还原
