What is the organic Rankine cycle?
Organic Rankine Cycles (ORC) are systems that can effectively recover low-grade heat for electric power generation. For ORC to be a viable technology, it should operate safely and efficiently under variable operating conditions due to exogenous and operating specifications changes.
How does an ORC plant work?
The ORC turbogenerator uses medium-to-high-temperature thermal oil to preheat and vaporize a suitable organic working fluid in the evaporator (4>5). The organic fluid vapor rotates the turbine (5>6), which is directly coupled to the electric generator, resulting in clean, reliable electric power.
What are organic fluids for Rankine cycle?
The choice of the organic fluids was based on previous reports [4, [62] [63][64], where the best efficiencies for the organic Rankine cycles operated in similar conditions to those of the present study were obtained with benzene, toluene, and cyclohexane.
How much does organic Rankine cycle cost?
It is shown that by utilizing the full potential of screw expanders instead of turbines, it is possible to produce Organic Rankine Cycle (ORC) systems at these outputs, which can be installed for a cost in the range of $1500 to $2000 /kWe of net output.
