Abstract: Testing samples of super fine pulverized coal and common pulverized coal were made from Heshan coal.Contrast test of combustion characteristics, NO_x and SO₂ 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 NOx emission,efficient sulfur removal,etc.
