- Abstract
At present, Selective Catalytic Reduction (SCR) flue gas denitrification process has been widely used in coal power plants in China. Catalyst is the core of SCR denitrification system. Because of the influence of the fly ash, erosion and chemical poisoning, the catalyst activity can be reduced gradually, and the performance of the denitrification will be also reduced gradually. So it is significant to predict the safety and performance of the system. However, due to the limitation of laboratory test conditions, the test results can not completely reflect the actual situation of denitrification reactor, so this paper proposes the data of field performance tests of denitrification system to be modified, namely while laboratory test data of the catalyst used to control the degressive rate of the catalyst activity, the field test data of the denitrification system used to control the actual denitrification performance of the reactor. Meanwhile, this paper introduces the practice of the catalyst performance prediction fora 1000MW unit, which would provide a scientific basis for the management of SCR flue gas denitrification system.
