An experimental study of the nitric oxide emission from pulverized blended coal flames as a function of blending mass ratio is presented. Coals of three ranks (anthracite, bituminous, and lignite), and of the same rank (bituminous), but of different origin (Oklahoma and Wyoming mines), were used as fuels. Also, their blends (anthracite-bituminous, anthracite-lignite, lignite-bituminous, and Oklahoma-Wyoming coals) at mass ratios of 20:80, 40:60, 60:40, and 80:20 were studied. Correlations of nitric oxide emission index (mass/unit energy release) with blend mass ratio are presented.
