摘　　要：基于国华宁东电厂330MW 循环流化床锅炉检修中的水冷壁管壁厚度测量数据,研究了炉膛不同区域水冷壁的磨损情况,以及防磨梁对水冷壁磨损造成的影响,结果表明,炉膛不同高度和墙面的磨损程度及分布均有较大差别;炉膛中上部区域后墙和左、右墙磨损多为侧向磨损;设置防磨梁后其下部区域水冷壁管磨损得到有效减轻;当前,#1 锅炉水冷壁的磨损速率为0.02～0.03μm/h.根据测量和分析结果,提出了相应的锅炉水冷壁防磨建议.Based on the water wall tube wall thickness measurement data of a 330 MW circulating fluidized bed boiler in Guohua Ningdong Power Station,abrasion of water wall tubes in different areas and the influ?ence of anti-wear beams are studied. Results show that abrasion of water wall tube at different height and different wall are quite different. The abrasion pattern of water wall tube on the rear ,left and right wall at the upper part of furnace are side-abrasion. Abrasion of the water wall tube under the anti-wear beams are decrease drastically. The abrasion rate of #1 boiler water wall is about 0.02~0.03μm/h. According to the re?sult of the measurement and analysis,corresponding anti-wear suggests for boiler water wall are given.
