Based on the issue of ammonia injection unsymmetrical in a 600MW unit of Coal-fired power plant Shenhua Guoneng Group , the adjustment and optimization test of ammonia of denitrification system is conducted . Main steps of ammonia injection optimization adjustment are as follows: commissioning the manual ammonia injection valve , be familiar with the influence of valve opening on the flow of ammonia injection , fine adjustment manual valve; at the same time , regulate the control manner and reduce the ammonia injection at the lowest degree . This test can reduce the ammonia injection quantity as well as protect the operation safety of downstream equipment .
