超超临界锅炉A修后水压试验方案优化与应用

Optimization and Application of Hydrostatic Test Scheme in Ultra-Supercritical Boiler after Class-A Repair

采用柱塞泵替代电动给水泵对锅炉A修后进行打压,不仅降低了对机侧系统的依赖程度,还节省了厂用电、提高了电动给水泵安全性。

Using piston pump to replace electrically driven feed-water pump in uhra-supercritical boiler after class-A repair, which not only reduces the dependence on side system, but also saves the auxiliary power and improves the security of electrically driven feed-water pump.
