文章从投入产出效率角度出发,在考虑入厂标煤单价的基础上,综合分析厂内运营成本、副产品价值等环节,提出火电厂“每万元采购成本形成的经济效益”概念,以反映不同煤种内涵的真实经济价值。并以淮南煤和北方典型煤为例进行对比,得出结论:在相同的入厂标煤单价前提下,淮南煤每万元采购额形成的经济效益大于北方典型煤;而当淮南煤平均加价在30元/t左右,两种煤每万元采购成本形成的经济效益接近一致。
Based on the consideration of unit price of standard coal and comprehensive analysis of operating costs and by-products value in the process of input-output efficiency, this paper puts forward the concept of “economic benefits formed by procurement cost per ten thousand yuan” To reflect the real economic value of different types of coal connotation. Taking Huainan coal and northern typical coal as examples, it is concluded that the economic benefit of Huainan coal purchasing per 10,000 yuan is greater than that of northern typical coal under the same unit price of standard coal; and when the average price of Huainan coal increases In the 30 yuan / t or so, two kinds of coal per million procurement costs formed by the economic benefits of close agreement.
