Optimisation of Ammonia Injection in SCR Denitrification System Based on Grid Modification+Grid Method
In view of the problems such as excessive ammonia escape caused by SCR denitration system and clogging of air preheater,an optimization of ammonia injection based on grid transformation method was proposed.By this method,the amount of ammonia injected can be reduced effectively,the ammonia escape can be controlled within 3 ppm,and the air preheater jam can be alleviated.
