Steam Turbine Condensing or Extraction Industrial

Extracting type or condensing type steam turbines are common in all appliions. In an extracting type turbine, steam is released from various stages of the turbine, and used for industrial process needs or sent to boiler feed water heaters to improve overall cycle efficiency. Extraction flows may be controlled with a valve, or left uncontrolled.
