Flue gas recirculation for NOx control IEA Clean Coal …

Flue gas recirculation alone in coal-fired boilers achieves a low NOx reduction efficiency (<20%). This is because the ratio of thermal-NOx to total NOx emissions is relatively low in coal-fired plants. The technique is being used on coal-fired units in combination with other primary measures for NOx control.
