600MW亚临界机组二级减温水调节阀内漏原因及处理过程分析

本论文综述了岱海电厂600MW亚临界机组二级减温水调节阀内漏原因及处理过程分析:简述了该问题涉及的主要危害,原因分析及应对措施、解决方案及调节阀内漏量的简要计算过程,对同容量600MW亚临界机组如何预防过热器减温水调节阀内漏具有重要借鉴意义。

This thesis introduces inner leakage of the control valve in the secondary attemperating water system and about the treating processes in the boiler 600MW unit: sketch the harm to the system,analysis the reasons and the solutions,and the brief calculation about the leakage. At the end, it can be used for reference to the power plant which have the same capability(600MW subcritical unit) about the inner leakage of the control valve in the secondary attemperating water system.
