TEST AND STUDY ON COMPREHENSIVE ECONOMIC ASPECTS OF COAL SORTS[J]. Thermal power generation, 2004, (5): 5-8. DOI: 10.19666/j.rlfd.2004.05.002.
煤种综合经济性的试验研究
摘要
煤质变化会引起电厂发电成本的改变。比较了 4种煤在 2个不同发电负荷下的运行经济性
分别计算了各工况的燃料成本、排放成本、辅机耗电成本
分析了煤种对各项成本的影响及其差异。结果表明
煤种对燃料成本的影响最大
而燃料成本占发电总成本的份额最高
应予以重视。
Abstract
Variation of coal sorts can lead to change of the generating cost in a power plant. The operation economic aspects of four coal sorts under two different generating loads have been compared by using test method
the fuel cost
emission cost
electricity consumption cost of auxiliaries being calculated respectively
and the infuence of coal sorts upon every cost and difference of the said influences being analysed. The results show that the influence of coal sorts upon the fuel cost to be the greatest
and the share of fuel cost in total generating cost to be the highest
