Abstract
The working principle and steps of on-line setting for safety valves installed on pipeline of boiler no.2 for ultra-supercritical unit in Huaneng Yuhuan Power Plant after one year operation and at the end of first B-level repair have presented
and the result of setting being analysed.In the process of setting
utilization of high power machine and tools from power-supplying box of the on-line setting instruments should be avoided as possible
and many times of bolt adjustment should also be avoided.Combining with problems encountered in the setting process
