ZHANG Shouyan, YAO Chuang. Transformation Analysis of SCR Denitration System of Opposed Combustion Boiler of 330 MW Coal-fired Unit[J]. 2021, 40(5): 47-50.DOI:
In view of the problems of increasing ammonia escape and blocking of air preheater caused by excessive ammonia injection in coal-fired power plants to meet the requirements of nitrogen oxide emission reduction of environmental protection departments
This paper introduces the unit and equipment
analyzes the existing problems of the denitration system
and puts forward the transformation measures for the denitration system
such as flow field transformation
denitration control optimization and accurate ammonia control in SCR outlet zone.Through the test
it is confirmed that the transformation measures can effectively solve the existing problems of the current equipment and realize safe and efficient operation of the unit.
