Boiler rankine cycle
There are four processes in the Rankine cycle. The states are identified by numbers (in brown) in the T–s diagram. Process 1–2: The working fluid is pumped from low to high pressure. As the fluid is a liquid at this stage, the pump requires little input energy. Process 1-2 is isentropic compression.Process 2–3: … Mehr anzeigen The Rankine cycle is an idealized thermodynamic cycle describing the process by which certain heat engines, such as steam turbines or reciprocating steam engines, allow mechanical work to be extracted … Mehr anzeigen The overall thermodynamic efficiency can be increased by raising the average heat input temperature $${\displaystyle {\bar {T}}_{\text{in}}={\frac {\int _{2}^{3}T\,dQ}{Q_{\text{in}}}}}$$ of that cycle. … Mehr anzeigen The Rankine cycle applied using a supercritical fluid combines the concepts of heat regeneration and supercritical Rankine cycle into a unified process called the regenerative supercritical cycle (RGSC). It is optimised for temperature sources … Mehr anzeigen The Rankine cycle closely describes the process by which steam engines commonly found in thermal power generation plants harness … Mehr anzeigen In a real power-plant cycle (the name "Rankine" cycle is used only for the ideal cycle), the compression by the pump and the expansion in the turbine are not isentropic. In … Mehr anzeigen The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane or toluene in place of water and steam.
