- A three-dimensional SCR reactor model of 660MW coal fired unit was established by using FLUENT coupled detailed reaction kinetics. The effect of different ammonia injection strategies and the specific surface area of catalyst on the denitrification reaction were studied by the model. The results show thatï¼šfor the catalysts just putting into operationï¼Œdenitrification reaction was mainly accomplished in the first layer catalystï¼Œthe second layer catalyst mainly plays a role in the absorption of ammonia. The effect of denitrification was the same whether using 30 zones ammonia injection strategy or using 10 zones ammonia injection strategy. When SCR catalysts were putting into operation after a period of timeï¼Œas the first layer catalyst has the problem of plug and wearï¼Œthe denitrification efficiency was reduced and the ammonia slip was increased. At this pointï¼Œthe effect of 30 zones ammonia injection strategy was slightly better than 10 zones ammonia injection strategy.
