【摘要】 燃料再燃是诸多炉内脱氮方法中最有效且有前途的技术之一。选用 5种煤 ,在大型一维热态试验炉上对超细煤粉再燃降低NOx 的排放进行了大量的试验研究 ,得出了煤粉细度、再燃量、再燃温度及再燃区停留时间等因素对NOx 排放的影响规律 ,为超细粉降低NOx 排放提供了试验和理论依据更多还原

【Abstract】 Fuel reburning is one of the most effective and prospective technologies for NO_x reduction in the furnace. A vast amount of test and study on NO_x reduction with micronized coaldust reburning have been carried out in a unidimentional hotstate test facility with 5 sorts of coal, obtaining regularity of some influencing factors, such as coaldust fineness, reburning quantity, reburning temperature, and residence time in the reburning zone etc., upon NO_x emission from the boiler, providing test and theoretical basis for reducing NO_x emission with micronized coaldust reburning.更多还原
