摘　　要：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 .Testing samples of super fine pulverized coal and common pulverized coal were made from Heshan coal.Contrast test of combustion characteristics,NO_ x and SO_2 emission property,air staging combustion of super fine pulverized coal and common pulverized coal were carried out in a tunnel furnace with a single parallel flow burner. Experimental investigation proved that super fine pulverized coal has many advantages over common pulverized coal during combustion process,such as lower ignition temperature,better combustion stability,higher combustion efficiency,lower NO_ x emission,efficient sulfur removal,etc .
