GE, Alstom, 600 MW, Coal-Fired Steam Turbine Generator

Description

  1. Overview
    1. This unit 1 power block is a coal-fired electric generating unit comprising a nominal 600 MW GE steam turbine, tandem-compound 4-flow single reheat unit with throttle conditions of 3500 psig, 1050°F/1100°F.
    2. The Alstom steam generator is rated at approximately 4,650,000 lbs per hour capable of burning bituminous coal only or a combination of bituminous coal and petcoke (up to a 70%/30% blend).
    3. Coal pulverizers have significant design margin operating at ~70% for MCR firing.
    4. The plant design heat rate with this power block is 8725 BTU/kw-hr with turbine control valves wide open (VWO) and average ambient conditions in southeastern U.S. with a circular mechanical forced draft cooling tower, an electrostatic precipitator, and a wet limestone flue gas desulphurization system.
    5. All cycle design has been incorporated into the equipment for sale and cycle information is available for all other normally desired conditions.
