Description:
The report gives results of an analysis of long-term NO emission monitoring data from nine pulverized-coal-fired utility boilers. These data were in the form of hourly averaged NO, O2 (or CO2), and load: NO and O2/CO2 were measured with certified continuous emission analyzers. The analyses were compared to the emissions limitations in both the 1971 and 1978 New Source Performance Standards (NSPS). The comparison with the 1978 NSPS showed that seven of the nine boilers would have produced no periods of excess NO emissions on a 30-day rolling average basis. In addition, the same seven boilers would have complied with the 1978 NSPS NOx performance test requirements. Recommendations are made to more fully analyze the operation of two of these boilers to determine if their mode of operation could be adopted by other boilers. These boilers use permanently installed CO monitors to allow operation at the lowest practical excess air to achieve either low NO emissions or better fuel efficiency.
