Abstract: SCR is widely used in the power plants for the reducing of NOx. In addition, the cost of catalyst is so high. Researches on the management of the catalyst for SCR systems are conducted by us. This research concentrates on the changing method for the catalyst, strategy for the changing of the catalyst, models for the changing of catalyzer considering the economical effect. Our research on the strategy of changing of catalyst of SCR systems is very important for catching up with foreign countries on the managing strategy on the catalyst. In addition, this research is important for the running of SCR systems in our country, which is both science and technology value.

Key words: Power plants, SCR, changing of catalyst
