There was no significant change in NOx concentration in the case of 5 and 10% co-firing rate compared to the case of single coal combustion. However, as increasing co-firing rate to 15 and 20%, NOx concentration also increased, and the concentration at co-firing rate of 20% was approximately 20% higher than that at single coal combustion.
