ShiHeng Power Plant Boiler Leakage Analysis Of The Causes And Countermeasure Research

This paper mainly introduces the reasons of"Four Pipe Leakiness"in the electricity station boiler and the measures of how to prevent. The boiler is the main equipment in the power plant, the boiler system's parameter is mutative, the medium in hearth is keeping flow all along. Being scoured, the pipe is frayed. Reducing the speed of abrasion and early prevention are good measures. According to Statistic,in the unit trouble have to be tripped out of the plan,"Four Pipe Leakiness"proportion is over 30%. Starting and stopping frequently, influence the economy of the power plant and the life the boiler, so how to prevention and cure the"Four Tube Leakiness"is the point in the power plant. Talking about the four important heater (the waterwall,the reheater,the superheater and the economizer),analyses respective material structure,environment,running characteristic etc. Contacting the actual circumstance of Shiheng Power Plant, analyze completely the reasons which result in"Four Pipe Leakiness", institute corresponding precautionary measure. After implementing these measures, the"Four Pipe Leakiness"could be controlled efficaciously,has achieved good economic and security benefits.
