Abstract

The PowerSmith Cogeneration facility is a 120-megawatt (MW) combined cycle, cogeneration plant located near Oklahoma City, Okla. The plant was commissioned into commercial operation in September 1989. It is configured around a GE Frame 7EA1 gas turbine (natural gas fired) exhausting into a Zurn heat recovery steam generator (HRSG) train that produces steam at three pressure levels. Steam from the HRSG is used to run a GE 44.4-MW auto-extraction, condensing steam turbine generator set. Duct burner firing occurs on average 12% of total operating time. The plant also uses a steam injection system for nitrogen oxide (NOx) control. Most intermediate-pressure steam (IP steam) is exported for process and heating to a host plant nearby ﾖ the Dayton Bridgestone Firestone facility. Low-pressure steam is used for boiler feedwater deaeration. Turbine exhaust steam is condensed in a Yuba condenser, tied to a 4-cell Hammond cooling tower. Figure 1 shows to cogeneration facility.
