Presented are the results from both short term optimization testing and long term emission monitoring obtained during the first time application of the controlled-flow, split-flame (CF/SF) low-NOx burner design, used on wall fired boilers, to a boiler having a tangential firing design. Goal of this demonstration was to achieve desired NOx emission reductions, and to develop a production model tangential low NOx (TLN) burner design based upon a prototype burner system installed in 1992. Installation of this burner system occurred without the modification of waterwalls, or addition of separated over fire air. During testing of the prototype TLN burner system, it was found that a combination of optimized burners along with vertical secondary air staging provided the desired emission reduction over the entire boiler load range. Data reported is from the operational testing of the production model tangential low NOx, CF/SF burner system, which was installed in 1994.
