Impact of air staging along furnace height on ... - DeepDyve

Jun 01, 2010 · In middle air-staged degree combustion with f M = 0.75, pulverized coal fineness, R 90 (%), has a greater influence on NO x emission, whereas R 90 has little influence on NO x emission for deep air-staged degree with f M = 0.61. Air-staged combustion with proper burnout air position has little effect on the burnout.
