Analysis of Low NOx Operation of Two Pulverized-Coal Fired Utility Boilers

摘要

The report gives results of a review of the operation of two pulverized-coal-fired utility boilers subject to the 1971 New Source Performance Standard, to determine if other boilers could adopt a similar mode of operation to reduce nitrogen oxide (NOx) emissions. These two boilers had been identified, during a previous study, as low NOx emission sources. It was determined that reburnering, burner modification, or optimization of the overfire air system of existing Foster Wheeler boilers offered the potential to significantly reduce NOx emissions. It was also determined that existing Babcock and Wilcox boilers would probably not respond to further combustion modifications.
