SPX to Design and Install Flue Gas Discharge System at Cardinal

SPX Corp.’s Thermal Equipment and Services segment was awarded a contract in September of approximately $47 million to install a state-of-the-art flue gas discharge system and other upgrades to enhance the existing natural draft cooling tower at 1830-MW coal-fired Cardinal Station. Treated flue gases will be conveyed from the FGD system into the cooling tower through one or two glass-fiber reinforced plastic ducts and discharged into the atmosphere together with the cooling tower plume. This combination of flow allows for improved mixing and updraft into the atmosphere.

"Our flue gas discharge technology can help some new and existing coal-fired plants using natural draft cooling towers achieve enhanced cooling efficiencies," said Drew Ladau, SPX segment president. "And in some cases it may even potentially reduce costs," he added. Preliminary on-site work on the cooling system retrofit will begin as early as this year. The final flue gas discharge system installation is expected to be completed in 2012 during the commissioning of a new FGD system that Cardinal Station expects will reduce SO₂ emissions by more than 98 percent.
