CFB锅炉水冷壁磨损防护措施及质量控制

The Protective Measures and Quality Control of CFB Boiler Water Wall Wear

针对CFB锅炉水冷壁管由于炉内飞灰颗粒浓度较大磨损较为严重,经常发生水冷壁漏泄、爆管的问题,阐述了水冷壁磨损机理,分析水冷壁的主要磨损部位和原因,制定相应的防护及质量控制措施,降低水冷壁管束的磨损程度。

Aiming at the critical wear of the CFB boiler water wall tubes caused of serious large granule concentration of fly ash,which often occurs water wall leakage and tube-burst problems,expounds the wear mechanism of water wall,analyze the main wear parts of water wall and reasons,formulates corresponding protection and quality control measures,so as to reduce the wear degree of water wall bundle.
