Non-Reheat Steam Turbine STF-D200

The STF-D200 and STF-A200 work well for combined-cycle conversion projects when a bottoming cycle is added to an existing simple-cycle plant to increase power output and efficiency upwards of 50 percent. 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. Depending on machine size, standard sections and multi pre-packaged units are available to minimize installation and startup times.

  • 200-340 MW output and up to 39.1 percent efficiency

  • Double flow LP section with available side exhaust lowers the centerline for reduced plant costs

  • HP section is shipped fully assembled, enabling a five-month installation cycle from arrival on-site to turning gear operation
