Description

Technical field [0001] The present application relates to the field of flue gas treatment, and in particular, to a micro NOx purification reaction activity evaluation system. Background technique [0002] The garbage incineration method is an effective waste treatment, but its combustion generates harmful substances such as NOx and SOX. Therefore, a large number of new NOx purification materials come into born. However, the garbage component is complex, the incineration reaction is severe, the combustion process is affected by an oxygen content, the multi-stage air volume, the working condition of the incinerator is in a large fluctuating state, and it is difficult to ensure that the test conditions are consistent when evaluating. [0003] At present, the evaluation of purification materials is the evaluation model of the effect of on-site feeding. It is very vulnerable to the influence of garbage components and incinerator conditions. It is difficult to accurately evaluate the r...
