| 摘 要： | 为了降低410t/h电站煤粉锅炉的NOx排放,在实炉上进行了热态试验,在最上层二次风喷口的上方装设了分离式燃尽风(SOFA)喷口.试验结果表明,投入分离式燃尽风SOFA后,炉内形成了良好的空气分级燃烧工况,显著降低了NOx的排放浓度,最高降低了43.4%.二次风缩腰型配风方式相较于宝塔型配风方式,更有利于降低NOx排放...

| Abstract: | In order to decrease the NO_x emissions in a 410 t/h power plant located in Xin Jiang,a hot-state experiment was conducted on the boiler and separated over fire air(SOFA) nozzles were installed above the top secondary air nozzles.It was indicted in the experiment that appropriate aerodynamic field was established after the application of SOFA and the NO_x emissions decreased apparently up to 43.4%.Meanwhile,the constricted air distribution mode was proved more efficient for the NO_x reduction in comparison ... |
