Over the last several years, DB Riley has been involved in a number of gas and oil low NO{sub x} retrofits for both utility and industrial boiler applications. The boilers retrofitted have included conventional front wall and opposed fired units, a cell fired unit, and Riley flat bottom Turbo{reg_sign} units. The Riley Turbo{reg_sign} applications featured modifications of the existing Directional Flame burners while the other applications featured installation of DB Riley Swirl Tertiary Separation (STS{trademark}) burners and Holman Boiler Works Environmentally Designed for Guaranteed Emissions (E.D.G.E.) low NO{sub x} burners (LNB`s). This paper provides a brief summary of the design, start up, and operating considerations as well as performance results. NO{sub x} guarantees met for the applications firing oil ranged from 0.28--0.40 lb/MMBtu while CO was less than 100 ppm volume, dry basis, corrected to 3% O{sub 2} (vdc). NO{sub x} guarantees met for the applications firing gas ranged from 0.10--0.35 lb/MMBtu while CO was generally less than 100 ppm by volume, dry, corrected to 3% O{sub 2} (vdc).
