This research was conducted to provide a guide or reference that could quickly and easily be used to determine the optimum power output and choose the most efficient energy conversion technology. Three energy conversion models were analyzed and simulated. A single flash plant was chosen as the main energy conversion system due to its simplicity and reliability. Two other energy conversion systems were considered as the bottoming unit of the single flash, double flash and Organic Rankine Cycle (ORC). Also their combination with district heating system was investigated. Engineering equation solver software (EES) was used for modeling and simulation. Comparison of power output for three cycles show that ORC cycle is more efficient from the view of power output. Also it has the highest thermal efficiency when district heating is added for heat recovery of waste heat from plant.
