| 摘 要： | This paper reports a field testing of full scale PCC (Pulverized Coal Combustion) boiler study into the influence of constricted air distribution on NOx emissions at unit 3 ( 125 MW power units, 420 t/h boiler) of Guixi power station, Jiangxi and puts forward the methads to decrease NOx emissions and the principle of boiler operation and regulation through analyzing NOx emissions state under real running condition. Based on boiler constdcted air distdbution, the expedment mainly tested the influence of primary air, excessive air, boiler load and milling sets (tertiary air) on NOx emissions and found its influence charactedstics. A degraded bituminous coal is simply adopted to avoid the test results from other factors.

Based on boiler constricted air distribution, the experiment mainly tested the influence of primary air, excessive air, boiler load and milling sets (tertiary air) on NO x emissions and found its influence characteristics. A degraded bituminous coal is simply adopted to avoid the test results from other factors. |
