Abstract
This paper analyzes the existing ammonia escape measurement techniques and the existing problems in the SCR exit NO
x
measurement method and puts forward the ammonia escape in situ sampling measurement method
and the high precision NO
x
zonal synchronous measurement method. The fined ammonia injection control of SCR system is realized by partition ammonia injection.The application results show that this method can effectively improve the operation level of SCR and reduce the amount of ammonia escape.
