Abstract:The inspection of reheater attemperator is an important part of routine maintenance of gas turbine.This article described the water inlet pipe of desuperheater weld crack phenomenon found in the routine maintenance of 6 gas turbine,and analyzed the reason of desuperheater weld cracking and fracture. On one of the gas turbine desuperheater,the inlet pipe and the heat exchanger casing structure were improved. After more than 2 years of operation,it's currently running in good condition.
