Excerpt: ... Coal Oxygen from Air Power Block Slurry Separation Plant The gas turbine is a General Elec-tric model MS 7001FA, designed for low NOx emissions when fired with Texaco syngas and with low-sulfur fuel oil that Gasifier is used for startup and backup. Rated output from the hydrogen-cooled gen-erator when syngas is fired is 192 MWe. The gas turbine uses an ad-vanced design that has been proven in a utility environment. Nitrogen is used as a syngas diluent to reduce NOx formation Feed and to increase mass flow, resulting Water in higher power output from the gas turbine. The heat recovery steam generator ( HRSG ) is a three-pressure design with natural circulation and reheat. The exhaust gas leaving the HRSG is vented to the atmosphere via a 150-ft stack. The steam from the Radiant HRSG flows to a steam turbine, which Syngas is a double flow reheat unit with low-Cooler pressure extraction. Nominal steam inlet conditions are 1450 psig and Syngas 1000 ° F with 1000 ° F reheat tempera-ture. Generator output during normal High operation is 121 MWe. Pressure Steam Total power production is 192 MWe from the gas turbine and 121 MWe from the steam turbine, giving a total of 313 MWe. With parasitic power of 63 MWe, total net power output is 250 " Black Water " MWe. Recycled Air Separation Unit Slag to The conventional air separation unit Disposal provides 95 % pure oxygen for the gas-A single Texaco gasifier processes 2,200 tons per day of coal to produce ifier operation, and warmed com-a raw syngas and molten slag. The gas flows downward into the radiant pressed nitrogen for the gas turbine. syngas cooler where it is partly cooled and high-pressure steam for power Low-pressure 95 % oxygen is also sup-generation is produced.
