What is the organic Rankine cycle?
An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.
What are the steps in the organic Rankine cycle?
Similar to a simple Rankine cycle, a basic organic Rankine cycle (ORC) consists of four processes: increasing pressure of the working fluid through a pump, high temperature heat addition through an evaporator, expansion of the high temperature as well as high pressure fluid through a turbine, and low temperature heat ...
What is the Rankine cycle explained?
The Rankine cycle, also called the Rankine vapor cycle, is a thermodynamic cycle that converts heat into mechanical energy. The Rankine cycle is name after William Johnson Macquorn Rankine, a 19th century Scottish engineer and physicist known for his research in the thermodynamic properties of steam.
What are the four main components of Rankine cycle?
The four main components of the Rankine cycle are the water pump, boiler, turbine, and condenser. There are four main stages to the Rankine cycle. Compression, heating, expansion, and condensation of the working fluid. The Rankine cycle can be represented by a pressure-volume diagram for each stage.
