The two most common types of low NOx burners being applied to natural gas-fired boilers are staged air burners and staged fuel burners. NOx emission reductions of 40 to 85 percent (relative to uncontrolled emission levels) have been observed with low NOx burners. Other combustion staging techniques which have been applied to natural gas-fired
Read Moretechnologies reduce the NOx present in the flue gas away from the primary combustion zone. Some of the secondary control technologies actually use a second stage of combustion, such as reburning.[2] 2.1 Primary Control Technologies: For NOx emissions control, popular primary technologies are low-NOx burners (LNB) and OFA.
