Abstract

In the present paper, a rigorous analysis of a sub-critical steam power plant (120 MW) with reheating and regenerative configuration is presented, using energy and exergy analysis. The total work output from the power plant is 121.80 MW, which is close to the real value of 120 MW. The calculated energy efficiency of the steam power plant is 34.7%, while its exergy efficiency is 32%. In addition to it, energy analysis introduces the condenser as a major source of heat loss, on other hand, exergy analysis introduces the boiler as a major source of exergy destruction. Further to understand the effect of main steam temperature, reheating temperature and condenser pressure on the power plant, a parametric study is being conducted.

火用分析在120mw单热回热燃煤电厂性能分析中的应用

本文采用能量分析和火用分析的方法，对带再热回热配置的120 MW亚临界蒸汽电厂进行了严格的分析。电厂的总发电量为121.80兆瓦，接近实际值120兆瓦。该蒸汽电厂的计算能效为34.7%，其火用效率为32%。除此之外，能量分析将冷凝器作为热损失的主要来源，另一方面，火用分析将锅炉作为火用破坏的主要来源。为了进一步了解主蒸汽温度、再热温度和冷凝器压力对电厂的影响，进行了参数化研究。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
