The Southern Energy, Inc. (SEI) Birchwood Power Facility is successfully operating on coal maintaining stack NO{sub}x emissions below 0.10 lb/10{sup}6 Btu (73 ppmvd at 3% O{sub}2, 43 ng/J) on a 30-day rolling average. The cogeneration plant uses an integrated approach for controlling NO{sub}x including in-furnace reduction from a TFS 2000 firing system and post-combustion control from selective catalytic reduction (SCR). The plant began operation in November 1996, and continues to meet the State of Virginia's stringent environmental requirements under all operating conditions. This paper focuses upon recent performance and operation of the NO{sub}x control technologies. Operational data of the NO{sub}x emissions from the steam generator as well as those exiting the SCR are presented. In addition, the latest information from the Spring '99 outage is discussed.
