Topic presented is the performance of a controlled flow, split flame, low NO{sub x} burner system installed on a tangentially-fired furnace, identifying specifically the results of both short term optimization testing and long term emission monitoring. This installation was the first time application of the controlled-flow, split-flame (CF/SF) low-NO{sub x} burner design used on wall fired boilers, to a boiler having a tangential firing design. Installation of this low NO{sub x} burner system to the furnace occurred without the modification of waterwalls, or addition of separated overfire air. Technical benefit achieved is reduction of fuel NO{sub x} production on a per burner basis in a tangentially-fired boiler, with the burners operating at near stoichiometric conditions. Combination of optimized burners along with vertical secondary air staging was found to provide the desired emission reduction over the entire boiler load range. Ash LOI and unit efficiency values were found to remain consistent with pre conversion, baseline data values.
