Rankine cycle

A thermodynamic cycle widely used in thermal power plants in which thermal energy is converted into useful work, e.g. by means of a steam turbine. The Rankine cycle uses the temperature difference between the inlet and outlet of the turbine. First, the working medium (e.g. water) is compressed and heated, e.g. in a nuclear reactor or biomass combustion boiler. By heating above the boiling point, it is converted into a gas which is fed into the turbine blades. The steam expands in the turbine and spins it. The working fluid is then cooled and liquefied. The conversion efficiency of the Rankine cycle is determined by many factors, but is usually around 40 percent.
