摘　　要：平圩电厂HG2 0 0 8型 1号炉曾频繁发生水冷壁管横向裂纹泄漏。为查明原因 ,进行了水冷壁裂纹原因调查试验 ,调查了锅炉不同工况对水冷壁工质流量及水冷壁向火侧外壁管壁温度的影响规律 。Circumferencial cracking often occurred in Ping Wei Power Plant No.1 boiler water-wall. A test was accomplished to determine the cause of boiler tube failure.The tube wall temperature and water flow were recorded in different conditions.The cause of circumferential cracking is determined and a solution recommended
