空气预热器密封系统技术改造

Technique Reform on Air Preheater Seal System

某电厂锅炉空气预热器冷段出现低温腐蚀,锅炉热经济性下降等,严重影响了锅炉的安全运行,经检测为空气预热器密封系统存在漏风,在分析和调研的基础上,对其密封系统实施了技术改造,取得了良好效果。

The air preheater of boiler leaks air, ,so it causes the decrease of economic analysis. The result badly influences the safe operation of the boiler. Based on the investigation, the modification of technique was made and achieves the satisfactory effect.
