火电厂四大管道系统弯管弯头设计对比分析

The comparative analysis of bending and elbow in main service piping design of coal-fired power plant

介绍了上海外高桥第三发电厂2×1 000MW超超临界机组四大管道采用弯管设计的使用情况,分析了弯管代替弯头的技术优势。通过具体的数据对比可知,采用弯管设计可以减少投资、降低机组热耗率,达到节能减排的目的,同时有利于管道安全运行。

The application of bending design for main service piping adopted in 2×1 000 MW ultra-supercritical units of Shanghai Waigaoqiao Third Power Plant was introduced.The technical advantage of the replacement of elbow by using of bending was analyzed.The comparing of concrete data shows that the adoption of bending design can reduce the investment,decrease the heat consumption rate which is helpful for energy conservation and emission reduction,and the design is beneficial for the piping safe operation simultaneously.
