Title:
Effect of coal blending and particle size on NOx emission and burnout 
Abstract:
Investigations were undertaken with a 0.5 MW(th) test combustor burning pulverized coal, with burner or in-furnace air-staging. Significant dependences of NOx emission and unburnt carbon in fly ash on the flow conditions in the furnace, the blending ratio of high- and low-volatile coals and the fineness of the coal were observed. The lowest NOx emission, 180 ppmv, was achieved with in-furnace air-staging, at an unburnt carbon content of textasciitilde10 wt
