How to Reduce NOx: A Guide to Low Emission Boilers

Oct 12 2016 · Burners out of Service or BOOS is another technique for how to reduce NOx. This technique can be used for boilers with multiple burners. It includes taking one or more than one of the burners out of service which reduces the peak flame temperature. As a result NOx emissions can be significantly reduced by several mechanisms of combustion.
