DESIGN, SPECIFICATION, PROCUREMENT AND UNIQUE FEATURES OF AN FGD SYSTEM WITH WET STACK AND WASTE WATER TREATMENT FOR KEYSTONE GENERATING STATION, UNITS 1 AND 2

摘要

Keystone Generating Station is a 2 × 850 MW coal-fired generating station located in Plum Creek Township, Armstrong County, near Shelocta, Pennsylvania. The station is currently owned as an undivided interest by seven utilities and is managed and operated by Reliant Energy. After the FGD system goes into service, the units will burn high-sulfur eastern bituminous coal and operate base-loaded with an average annual capacity factor of approximately 90%. The FGD system uses limestone slurry to remove SO{sub}2 and in-situ forced oxidation followed by horizontal belt filters to produce commercial grade gypsum. A waste water treatment system processes the effluent from the FGD system to remove trace elements and solids before discharging. The presentation will include unique features of the system and details of performance requirements including SO{sub}2 removal, particulate emissions, mercury removal, quantity and quality of waste water effluent from the FGD system.
