Two kinds of typical coal (HSQ bituminous coal and LY anthracite coal) were selected as the object of research, and in the fixed bed reactor a series of research was carried to make a thorough inquiry on NO emission characteristics of coal combustion under different blending modes. The results of coal blended combustion show that: Improving the ratio of bituminous coal can advance the ignition and burnout, and improve the combustion performance of coal. When two kinds of coal burn blended, NO emission is between the concentration of these two kinds of single coal, and the NO conversion rate increases gradually with the growth of the proportion of anthracite; the interrelationship between these two kinds of coal has influence on NO emission, which is showed as form of inhibition or promotion when ratio of mixed coal is changed.
