【 摘 要 】

More stringent emission limits or the addition of post combustion NOx control create the need for improvements of NOx emissions from pulverized coal boilers. Low NOx combustion is likely to increase theunburned carbon in the fly ash which results in lower boiler efficiency and restrictions on ash sales. In addition, any imbalance of the air and/or coal supply to the burners has negative effects both on NOx emissions and unburned carbon levels.[first paragraph]
