The experimental research is performed to elucidate the influence of coal properties on the emission characteristics of NOx and the unburned carbon in fly ash from the pulverized coal combustion test facility (coal feed rate is 100kg/ hr).<BR>Under the constant experimental condition, the conversion of the fuel bond nitrogen to NOx is increased with the increase in the fuel ratio of the coal and with the decrease of the fuel bond nitrogen content in coal sample. The correlation to predict the NOx concentration from coal properties on pulverized coal combustion was presented and was found to be valid also for the combustion of blended coal. On the other hand, the unburned carbon fraction is increased with the increase of the fuel ratio of the coal. In the blended coal combustion, the unburned carbon fractions in each coal can be assumed to be the same as that of the single kind coal combustion.
