　　　摘要—火電廠消耗了大量的煤炭。值得注意的重要問題是火電廠有關(guān)部門是如何分析造成標(biāo)準(zhǔn)煤發(fā)電煤耗率增加的原因和地點，并為他們的電廠檢修提供節(jié)約能源和開發(fā)潛力的基礎(chǔ)。以火電廠為例，首先是運算確定經(jīng)濟狀態(tài)，突出的問題是發(fā)電標(biāo)準(zhǔn)煤耗率過高，因此，經(jīng)濟效益太低。并對鍋爐的熱效率和汽輪機的實際循環(huán)熱效率的測量，對使用煤耗率偏離目標(biāo)標(biāo)準(zhǔn)煤耗率產(chǎn)生的影響進行分析。指出確切的汽輪機低熱經(jīng)濟性運行性能。最后，確定判斷出造成汽輪機熱經(jīng)濟性能減少的原因和地點。對于火電廠來說，開發(fā)其潛在的節(jié)能和提高其經(jīng)濟運行效率的研究，具有非常偉大的意義。

　　　Abstract—large quantities of coal are consumed in fossil-thermal power plant. The general concerned question for operation departments in thermal power plant is how to analyze the reasons and sites which cause the standard coal consumption rate for generating increasing, and provide the basis to power plants for their overhauling and exploiting energy savings potential. Taking a fossil-thermal power plant for example, the operation economic state is identified firstly, and the viewpoint is pointed the standard coal consumption rate for generating is too high thus the economic efficiency is too low. Then the boiler thermal efficiency and steam turbine actual cycle thermal efficiency are measured, the effect of the efficiency deviating from target value on the standard coal consumption rate for generating is analyzed. The certain low operation thermal economic performance of steam turbine is pointed out. Finally, the diagnosis on the reasons and sites causing the thermal economic performance of steam turbine decreasing is conducted.
　　　The research has a great significance for the potential of exploiting energy savings and increasing the operation economic efficiency of fossil-thermal power plant.
