摘　　要：水冷壁拉裂问题是600 MW超临界W火焰锅炉面临的一个技术难题。通过调研已投运电厂的水冷壁拉裂情况,研究分析了水冷壁拉裂的原因,结果表明其根本原因是炉膛内水平方向上热负荷的偏差。最后给出了设置水冷壁中间完全混合集箱等防止水冷壁拉裂的建议措施。The water wall cracking is a big problem for 600 MW supercritical W-flame boiler. The investigation and survey results about 600 MW supercritical W-flame boiler water wall cracking were indicated. The reason of water wall cracking was analyzed according to the boiler operation. The main reason is the furnace thermal deviation in horizontal direction. The fully mixing header is provided on the transitional section of the water wall,which is the most useful method to prevent the water wall cracking.
