fuel feed rate from coal mill 5. Not feeding coal from coal mill 4 helps a lot in reducing NOx to a large extent, but it limits the amount of power that can be generated. This is also unfavourable from the point of view of unburnt carbon in ash. Figure 5. Effect of fraction of secondary air on NOx at different fuel flow rates from coal mill 5
