百万千瓦火电机组主蒸汽管道设计优化

Design optimization of main steam pipe in 1000MW power plant

结合主蒸汽管道材料应用和发展的现状,按照现行国家及行业标准和规范,并参考国际有关标准,对主蒸汽管道的材质进行优选;利用AFT、PEPSE软件对主蒸汽管道进行阻力、热平衡计算,对主蒸汽管道作经济性比较并进行管道规格优化,同时根据管道布置合理地选取弯管,降低管道阻力,降低热耗和煤耗,减少CO2的排放。

This article according to the status of main steam pipe material application and development,in accordance with the existing national and industry standards and norms,and in reference to international standards,is the optimization of the main steam pipe material;Using AFT,PEPSE software,resistance of main steam pipe heat balance calculation,as the economy on the pipeline of main steam pipe comparison optimization specification for pipeline.At the same time according to the piping layout reasonable selection of pipe,reducing pipe resistance,reduce the heat consumption and coal consumption,reduce emissions of CO2.
