| Abstract | This paper introduces the unique steam turbine supplied to Kizildere Geothermal Power Plant in Turkey, which was commissioned in September 2013. This power plant adopts a triple-flash system. The steam turbine and generator are rotated with the steam with three different pressures (high, intermediate and low) to generate electricity. A back-pressure system is adopted for a HP turbine which uses high-pressure steam, and a condensing system is adopted for ILP turbine, which uses intermediate and low pressure steam. This turbine system is tandem by coupling these two turbines to a single shaft. In addition to the uniqueness of steam turbine configuration, the high-pressure steam is also unique because it includes 16.7 weight% non-condensable gas, which is extremely high concentration compared with other geothermal power plants. |
