摘要：

Taking the case of the T23 steel water wall leakage in a 1000MW ultra-supercritical tower boiler as an example, the reasons why the T23 steel water wall leakage of this type tower boiler may take place easily were analyzed from several aspects such as the material characteristics of T23 steel, the jointing and welding technology, the heat sensitivity of water walls and the rationality of operating ways. Then the measures to decrease water wall leakage were brought in, which improved the operating security of the tower boiler.
