　　　摘要—火电厂消耗了大量的煤炭。值得注意的重要问题是火电厂有关部门是如何分析造成标准煤发电煤耗率增加的原因和地点，并为他们的电厂检修提供节约能源和开发潜力的基础。以火电厂为例，首先是运算确定经济状态，突出的问题是发电标准煤耗率过高，因此，经济效益太低。并对锅炉的热效率和汽轮机的实际循环热效率的测量，对使用煤耗率偏离目标标准煤耗率产生的影响进行分析。指出确切的汽轮机低热经济性运行性能。最后，确定判断出造成汽轮机热经济性能减少的原因和地点。对于火电厂来说，开发其潜在的节能和提高其经济运行效率的研究，具有非常伟大的意义。

　　　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.
