Organic Rankine Cycles differ from traditional steam Rankine Cycles in their use of an organic liquid as opposed to steam as the working fluid. The term ORC is also applied generally to any Rankine cycle with a low-grade heat source.

What is the difference between steam Rankine cycle and 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 Q in Rankine cycle?
Efficiency of Rankine Cycle
Let us consider these terms that are essential to calculate the efficiency of the cycle. Q = Rate of heat flow in the system (towards or away) WT = Mechanical work done by the turbine. WP = Mechanical work done by the pump.
What is the organic Rankine cycle of steam?
The ORC-concept has two circuits, one for thermal oil and another for organic fluid. Heat from burning fuel or industrial waste is led in via the oil-filled circuit at a temperature of 250–300 °C to the heat exchanger, creating steam and super heating the organic silicon fluid.
What is the cycle of steam in Rankine cycle?
In the Rankine cycle, steam is created in a boiler, and part of the enthalpy of the high-pressure superheated steam is converted to shaft work in a steam turbine that drives an electric generator.
