Causes analysis and treatment of 300 MW unit high pressure heater leakage

Aiming at the steel tube leakage of high pressure heater caused by severe environment in Huadian Inter- national Laicheng Power Plant, this paper expounds the leakage and its influence on the unit, and analyzes the cause. Through comparing the parameter change before and after the breaking, the paper proposes reasonable treat- ment. The practice proves that if the leakage can be detected at an early rate and be treated correctly, the accident is able to control so as to guarantee the safe and economic running of the unit.
