    This paper expounded tube explosion reasons of T23 material used in final stage superheater of 330 MW subcritical boiler. By the thorough analysis of running parameters, tube explosion site, secondary water temperature reduction operation, temperature fluctuation rate, this paper pointed out production and spalling mechanism of inner wall oxide scale of T23 pipe, and put forward prevention measures at the same time.
