摘要
Abstract
The operation control of SCR becomes more difficult after the ultra-emission retrofits.Some problems,such as,NOx emission exceeding the guideline standard and extensive air pre-heater blocking,are much easier to happen.Generally,these problems are treated with diagnosis and optimization experiments of SCR (DOES for short).However,the effectiveness of DOES is directly related to the state of the SCR equipments:on the condition of no equipment defects,DOES tends to achieve good results,otherwise,if severe defects existing in the equipments,the effectiveness of DOES' is poor,and the improvement on the original bad operation condition is limited.In this situation,the DOES functions is more like the fault diagnosis,which is able to find out the most possible causes for the SCR performance decreasing,and provide the technical evidence for the owner to take effective treatment to deal with the problems.关键词
