电站锅炉热管常见泄漏原因及主要特征
Causes and Characteristics for Frequent Tube Blasting of Utility Boiler
摘要
Abstract
Heating surface tubes of utility boiler widely contact the media of smoke,fire,ash,water,steam,scale and etc.The tubes,which have wicked and complex working conditions,often blast and result in leakage failure because of many reasons.These bring huge economic losses to the enterprises.Nine kinds of tube blasting reasons and their main representation characters were detailedly introduced.These tube blasting reasons include abrasive erosion,long-term overheating,short term overheating,hydrogen damage,corrosion fatigue,oxygen corrosion,stress corrosion,caustic corrosion and acid corrosion.It has important guiding significance to rapidly ascertain the causes and ultimately resolve the tube blasting problems of the utility boiler and to normalize boiler system operation.关键词
