In response to the problems in the automatic control of ammonia injection for selective catalytic reduction(SCR)denitrification in a 600 MW coal-fired unit,combined with the actual production situation of the unit,this paper analyzes and summarizes the automatic control of ammonia injection,and proposes optimization measures.Not only does it ensure the reliability of automatic ammonia injection control,but it can also reasonably control NOx emissions to meet environmental requirements and achieve the ultra-low emission target of the unit.
