Abstract
Determination of the design conditions for ORC is exceedingly difficult to optimize. The conditions must be identified the design parameters for an ORC system especially with selection of the working fluid and operating parameters of the components for better performance. This research is designed to address the design parameters variation for the better efficiency of the system and how the thermal energy available from the sources would be used to deliver for ORC system. And the potential economic concerns of such system in terms of practical application. The project deals in selection of working fluid, the efficiency variation of the system with respect to hot side temperature, cold side temperature, flow rate of the fluid, variation of heat supply etc. Simulation is carried out to model the above parameters in a software platform to construct the model to evaluate the work output, efficiency variation and exergy destruction. Thermo-economic analysis is carried out to optimize the economic and thermal output from ORC systems.
