What is the organic Rankine Cycle?
The organic Rankine cycle is is similar to the Rankine steam cycle, but uses an organic fluid such as refrigerants and hydrocarbons instead of water as the working fluid. The ordinary Rankine cycle uses thermal power to convert water to steam, which expands through a turbine in order to generate electricity.
What is the Rankine cycle Q?
The Rankine cycle is named after William John Macquorn Rankine, a Scottish polymath professor at Glasgow University. Heat energy is supplied to the system via a boiler where the working fluid (typically water) is converted to a high-pressure gaseous state (steam) in order to turn a turbine.
What are the advantages of organic Rankine Cycle?
ORC's can recover heat from waste streams at lower temperatures than is possible with conventional steam Rankine systems, and because ORCs operate at relatively low pressure, they can operate unattended and fully automated in most locations.
What is the efficiency of the ORC system?
* The efficiency of the ORC system is always optimized: on average at 50% load, electrical efficiency is still 90% of the nominal electrical efficiency.
In the search for the best working fluid, Wang et al. [15] proposed a method to select a zeotropic mixture for ORC with varying heat source temperatures, i.e., ...
