- and others
In response to the NYSDEC, Part 227 regulations for the emissions of nitrogen oxides (NO{sub x}), Orange and Rockland Utilities, Inc. (ORU) and Burns & Roe Company (BRC) evaluated the options available to reduce the NO{sub x} emissions at two oil and gas fired units at Bowline Point Generating Station. Replacement of all of the existing burners with new low NO{sub x} burners and possibly overfire air ports presents the most costly method of achieving this goal. Therefore, other methods of NO{sub x} reduction were considered including utilizing some form of off-stoichiometric, burners out of service (BOOS), firing. It was determined that the stringent emission limits could be met utilizing off-stoichiometric firing techniques. New oil gun atomizer tips allowing off-stoichiometric firing with mechanical atomization and swirlers of a new design are replacing the existing atomizers. The new hardware eliminates the problems of opacity while operating with off-stoichiometric firing.
