On May 6, the Phase II project of Zhejiang Company's Wenzhou Power Plant successfully reached the milestone of completing the boiler pipeline purging for Unit 3, marking a significant step towards the final commissioning stage. This purging operation utilized a combined method of depressurization and pressure stabilization, ensuring optimal control of key parameters. The boiler and its six main pipelines demonstrated stable expansion without any instances of overpressure or overheating on heat-exchange surfaces.
