Combined cycle power plant - Wikiped
The thermodynamic cycle of the basic combined cycle consists of two power plant cycles. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region.Get a Quote
THE ORGANIC RANKINE CYCLE FOR GEOTHERMAL POWER ?
Jan 01, 1982· Any discussion of the binary cycle as applied to geothermal power production should begin with a statement that the term “binary” as used here really refers to the use of the organic Rankine cycle in one of its many forms, and not the typical binary cycle where work is extracted from two different working fluids at the same time.Get a Quote
Rankine cycle - Wikiped
The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.Get a Quote
