Low NO{sub x} burner retrofits to 240 MW, 300 MW and 400 MW oil/gas fired utility boilers; Final performance results and lessons learned

Low NO{sub x} burners (LNBs) and new windbox baffles were retrofitted to eight residual oil/gas fired boilers totaling 2,680 MW of generating capacity in the Florida Power and Light Co. (FPL) system. These TODD Combustion designed LNBs were installed, from 1992 to 1995, to comply with a NO{sub x} Reasonably Available Control Technology (R.A.C.T.) determination associated with a moderate ozone non-attainment area in south Florida. LNBs were the primary means of NO{sub x} emission rate reduction, with an objective to achieve the maximum NO{sub x} reduction possible through burner hardware changes. Accordingly, the full focus of the project was on the capabilities of state-of-the-art LNB technology. These LNB retrofits were deemed successful based on the significant NO{sub x} reductions that were achieved. FPL`s contract requirements included consideration of unit performance and boiler component life impacts in addition to the traditional emission parameter guarantees. In striving to simultaneously meet all contract requirements, various burner design adjustments were implemented. As the project progressed, much was learned about LNBs and their effects on utility boilers as well as the effects of boiler equipment design and boiler conditions on NO{sub x} emission rates.
