浅谈循环流化床锅炉水冷壁磨损及预防

Brief Analysis on Wear and Prevention of Circulating Fluidized Bed Boiler Water-cooled Wall

循环流化床锅炉水冷壁是整个循环流化床锅炉汽水循环中的重要一环。水冷壁的换热方式主要为对流换热和辐射换热两种。在检验的过程中,发现水冷壁因磨损造成的损失巨大。针对不同的使用单位,制定科学、合理、有效的防磨措施,是检验工作延伸服务的一个重要内容。

Circulating fluidized bed boiler water-cooled wall forms a vital part in whole steam and water circulation of circulating fluidized bed boiler. Convection heat transfer and radiation heat transfer are two principal heat exchange methods for water-cooled wall. In the process of inspection, it’s recognized that wear of water-cooled wall causes a great loss. To formulate scientific, reasonable and effective wear prevention measure is the significant content in expanded service of inspection in terms of various units.
