Survey of Department of Defense Facilities with Low NOx Burners

Abstract : This study conducted a survey regarding recent experience with Low NOx Burners (LNBs) at Department of Defense facilities known to be operating or installing low nitrogen oxides-emitting burners on boilers. The data collected did not conclusively show that LNBs are chronically problematic, but a majority of the LNB-equipped boilers recorded in the data base reported problems with operation, installation, or commissioning. The most frequently reported problems were the failure of the units to reduce NOx emissions to the level promised and flame instability caused by a variety of factors.
