摘要
针对过热器减温水取水点由给水泵出口改至高压加热器出口的可行性问题,结合某300 MW机组具体参数,从经济性及安全性进行了分析,结果表明改造可提高机组运行的经济性,但会对机组运行的安全性造成一定影响,可为今后改造提供参考。
To study the feasibility of switching the intake point of desuperheating water from feed pump outlet to HP heater outlet of a 300 MW unit, an analysis was conducted on the economy and safety of the retrofit with specific unit parameters. Results show that the retrofit may help to improve the operation economy of the unit, but may impact its operation safety. This may serve as a reference for future retrofit of similar units.
