A six lb/hr laboratory furnace was used to investigate the nitrogen oxide (NO) emissions resulting from the combustion of three types of pulverized bituminous coal (Colorado, Western Kentucky, Pittsburgh No. 8), a Montana Powder River subbituminous coal, and a coal char. Fuel NO, which was isolated by replacement of air with an appropriate synthetic oxidant, comprised more than 75 percent of the total NO emissions over a wide range of flame conditions. Fuel nitrogen oxidation was insensitive to temperature changes except at very high flame temperatures. Under equivalent combustion conditions, total NO emissions were only slightly dependent on coal composition, because fuel nitrogen conversion decreased with increasing nitrogen content. Coal char had fuel nitrogen conversions that, although appreciable, were lower than those of coal, and that were only slightly dependent on burner aerodynamics.
