This code has played a positive role in accelerating the power construction and enhancing the design level and technical standard of ash and slag damming since its promulgation in 1995. As new requirements have come out for the design of ash and slag damming in fossil fuel power plants with the deepening of reforms and technical progress in power industry， this code is to be revised accordingly.
