将合山煤分别制成常规粒度的煤粉与超细化煤粉 .在单只水平直流燃烧器燃烧室内进行了常规煤粉与超细化煤粉的燃烧特性、空气分级燃烧NOx 排放特性、炉内喷钙对超细化煤粉与常规煤粉燃烧SO2 排放特性的影响的燃烧试验研究 .试验研究表明 ,超细化煤粉与常规煤粉比较 ,着火提前 ,着火稳定性好 ,燃尽效果好 ;分级燃烧对超细煤粉的NOx 排放量的降低效果更显著 ;在Ca/S摩尔比相同的条件下 ,超细化煤粉的固硫特性明显优于常规煤粉 .
Heshan coal was made into the conventional size of pulverized coal and ultrafine pulverized coal in a single horizontal DC burner combustion chamber of conventional pulverized coal and ultrafine pulverized coal combustion characteristics of air staged combustion NOx emissions, Experimental Study on the Effect of Calcium Filling in Furnace on the SO2 Emission Characteristics of Superfine Pulverized Coal and Conventional Pulverized Coal Combustion Experimental study shows that compared with the conventional pulverized coal, the ultrafine pulverized coal has better ignition stability and fire stability The effect of staged combustion on the reduction of NOx emission of the ultrafine pulverized coal is more remarkable. Under the same Ca / S molar ratio, the sulfur-fixing property of the ultrafine pulverized coal is obviously better than that of the conventional pulverized coal.
