摘要
采用超临界技术是提高火力发电热效率的主要途径之一。本文采用作者提出的矩阵正多面体优化方法,对超临界压力600MW机组热力系统进行了优化分析。计算结果表明该方法可确定回热系统最优参数,机组循环热效率可从原设计值的47.499％提高到48.003％。
The supercritical pressure technique is one of the main way to increase the thermal efficiency of power plant. In this paper a new optimiza-tion method——the matrix regular polyhedron method is developed and an optimum analysis for thermosystem of supercritical pressure 600 MW unit is described. The results show that the optimum regenerative parameters can be established by means of this methed, the unit cycle thermal efficiency can be increased to 48.003% from the original designed 47.499%.
