NON-REHEAT DOUBLE-FLOW AND AXIAL FLOW, NON-REHEAT COMBINED CYCLE STEAM TURBINES D200/A200 STEAM TURBINES


GE’s D200 and A200 steam turbines are ideal for non-reheat applications. The D200 is a two casing, double- flow LP machine, and the A200 is a compact axial exhaust design available in either a single or double casing. Both models are available with internally and externally controlled extractions to remove steam at any point along the steam path at the desired flow and pressure conditions. They are ideal for combined cycle conversion projects, when a bottoming cycle is added to an existing simple cycle plant. A combined cycle conversion will increase power plant output upwards of 50 percent, is fully dispatchable, and requires no additional fuel burn.


D200:

D200: Delivering Cost and Performance • HP ships fully assembled, enabling a five-month installation.


• LP moisture removal features improve performance and reliability, and its side-exhaust lowers the centerline for reduced plant costs.


A200: Compact and Robust


• Single casing configuration ships fully assembled, enabling a four-month installation.


• Adaptive stage technology controls low pressure extractions while intersections with valves are used for higher pressures.


• Depending on machine size, factory-tested pre-packaged units are available to minimize installation and startup times.
