Abstract

The single flash Takigami Geothermal Power Plant is located in the southwestern part of Oita prefecture, Kyushu Island, Japan, with installed capacity of 25 MW. Mathematical models for energy and exergy flows were developed and implemented in the Engineering Equation Solver (EES) software. The energy and exergy rates of the waste brine have been calculated. The parts of the system with largest exergy destruction were defined. The overall exergy and energy efficiency for whole system were obtained. Grassmann presentation of the overall exergy flow was illustrated. Exergy analysis was found to be a helpful and important tool for analyzing the geothermal plant from the view point of optimum usage of produced energy.
