超超临界2×660MW汽轮机高位布置给水泵选型与优化研究

Study on Selection and Optimization of Feedwater Pump for High Level Arranged Ultra-supercritical 2×660 MW Steam Turbine

660MW超超临界高位汽轮机布置工况下给水泵选型与优化研究,从技术路线、热经济型、布置位置、费用成本4个方面开展了可行性、可靠性、经济性、费用最低对比优化分析,提出单序列汽泵直排配置方案,达到系统简单、布置优化、热经济型最佳、费用最低,对高位汽轮机汽泵选型与优化具有借鉴意义。

In terms of study on selection and optimization of feedwater pump for high level arranged ultra-supercritical 660 MW steam turbine,this article carries out comparative optimization analysis of feasibility,reliability,economy,and lowest cost from the four aspects of technical route,thermal economy,layout location,and cost,and put forwards the single sequence steam pump vertical configuration scheme featured by simple system,optimized layout,optimal thermal economy,and the lowest cost,which is of reference significance to the selection and optimization of feedwater pump for high level arranged steam turbine.
