| Abstract | The first phase of Pamukuren Geothermal Project of Celikler Jeotermal was commissioned in October 2013. Electrical power production capacity of this plant will be in excess of 100 MW when phases two and three are completed. The Organic Rankine Cycle plant was optimized with normal butane as working fluid. Celikler Jeotermal chose the plant configuration with inflow radial turbine. The first phase consisted of two trains each with nominal capacity of 25 MW electrical power output. In this paper we present the geothermal resource design conditions, thermodynamic discussion for choice of working fluid and the basic design parameters of the Organic Rankine Cycle and the inflow radial turbine. Field performance of the associated Organic Rankine Cycle and turbine with the actual geothermal resource data will be evaluated, compared and contrasted. Comparison of the expected and actual plant performance will also be presented. |
