| Abstract: | In the light of big relative deviation of NOx concentration and excessive ammonia escapeat the denitration system outlet of a power boiler, the problem causes of the denitration system werefound out by the application of the field test and analysis and comparison methods. The solution ofinjecting ammonia optimization and adjustment was proposed. The results show that the relativedeviation of NOx concentration is controlled within 20% , as well as ammonia escape within 3 uL/L for the denitration system outlet, which get better effects. |
