热力系统优化的热经济性功能分析法

Functional Method of Heat Economy Analysis for Optimizing Thermal Power Systems

长期以来，最优系统构成的工程研究只是靠经验，而不是从系统的、分析的角度来确定其设计和运行的优化。在热力系统的设计和运行中，也没有把热力参数同经济因素直接联系起来。因此，系统热力参数的变化对经济性的影响常常是不明确的。本文主要介绍了热力系统优化的热经济性功能分析法和应用该方法的基本步骤，并应用朗肯循环加以说明。

Over a long period of time, the engineering research for the construction of optimum systems has been a matter of experience. The optimization of the system design and operation has not been realized by systematic and analytical means. Furthermore, the thermodynamic parameters have not been directly connected with economic factors in the design and operation of thermal systems. Therefore, it has not been clear how the variation of thermal parameters in the system affects the economy of thermal power plants. In this paper, the functional method of heat economy analysis for optimizing thermal power systems and the essential procedures for its application were depicted in detail. The application of this method to the Rankine cycle for thermal power generation was described and explained.
