PENTANE TURBINE

Analysis of a solar assisted micro- cogeneration ORC system


This low turbine entry temperature (compared with a gas turbine) is why the Rankine The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane or toluene in Pentane has the same formula, but has a structure of CH 3 CH 2 CH 2 CH 2 CH 3 with no branching. This gas then drives a turbine and generator to generate the power plant’s The pentane is heated until it vaporizes and these vapors expand to drive a special organic turbine. The turbine drives the generator, which in turn produces electricity.
