This article reports that the Mulberry cogeneration facility has several features that make it notable in the power field. A zero-discharge wastewater system, an inlet-air chilling system, a secondary boiler, and an extensive distributed-control system (DCS) for overall plant operation are examples. Ability to meet the two-stage NO{sub x}-emission limits -- 25 ppm during the first three years and 15 ppm thereafter -- is a unique challenge. The plant design allows the lower limit to be met now, and retrofit with different burners is possible if NO{sub x}-emission limits are tightened later. The facility, near Bartow in Polk County, Fla, is owned by Polk Power Partners LP, whose members include Central and South West Energy Inc (CSW) of Dallas and ARK Energy of Laguna Hills, Calif. The operating company, CSW Operations, is a subsidiary of CSW. Heart of the plant is a single gas-turbine (GT)/HRSG/steam-turbine combined cycle, providing electric power to Tampa Electric Co and Florida Power Corp, with up to 25,000 lb/hr of process steam for an adjacent ethanol plant which was developed by the facility`s partnership. Commercial operation of Mulberry began on Sept 2, 1994.
