Effect of Non-Condensable Gases on geothermal power plant performance. Case study: Kizildere Geothermal Power Plant-Turkey
Non-Condensable Gases (NCGs) are natural components of geothermal fluids, and they are a source of considerable capital and operating costs for power plants. The NCG content of geothermal steam varies over the world from almost zero to as much as 25% (wt). In this work, the influence of NCGs on the thermodynamic performance of geothermal power plants is analysed for various NCG content and ...

Exergy analysis and performance evaluation of Kizildere Geothermal Power Plant, Turkey
Conventional geothermal power plants (GPP) differ from fossil-fuel power plants (FFPP) in many ways. The most specific ones are that GPPs are not cyclic plants and the working fluid is not pure steam. Geothermal steam contains non-condensable gases (NCG) which degrade power plant efficiency. This discrepancy leads to two considerations in energy and exergy analysis of GPPs. One is that the amount ...

Performance optimisation of the combined single flash binary geothermal power plant
In this paper, the optimal operating conditions of a hypothetical combined single flash-binary geothermal power plant are investigated and performance analyses are performed based on Aydin-Germencik field in Turkey. The relationship between flashing pressure, turbine inlet pressure of the binary cycle and total heat transfer area of the heat exchanger are determined for maximum power output of ...

The effect of ambient temperature fluctuation on the performance of geothermal power plants
Seasonal and diurnal temperature fluctuations have significant effects on cooling water temperature and on the condenser temperature. The power produced by plants that utilise a low temperature resources, such as geothermal units, are more susceptible to ambient temperature fluctuations than conventional power plants. An exergy analysis was performed to evaluate the effect of ambient temperature ...
