RANKINE CYCLE – Thermopedia
1-2-3 Isobaric Heat Transfer.High pressure liquid enters the boiler from the feed pump (1) and is heated to the saturation temperature (2). Further addition of energy causes evaporation of the liquid until it is fully converted to saturated steam (3).
Heat recovery steam generator – Wikipedia
2019-10-10 · A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).
low-pressure evaporator – an overview ScienceDirect …
In this cycle, the strong solution from the G flows into the medium-pressure absorber (MPA) and LPA. The refrigerant liquid from C flows into a medium-pressure evaporator (MPE) and low-pressure evaporator (LPE). The refrigerant liquid in the MPE absorbs the heat from the LPA, evaporates into vapor, and is then absorbed by the strong solution in the MPA, which is cooled by the ambient air.
Evaporator – Wikipedia
2019-10-15 · The energy consumption for single-effect evaporators is very high and is most of the cost for an evaporation system. Putting together evaporators saves heat and thus requires less energy. Adding one evaporator to the original decreases energy consumption to 50%. Adding another effect reduces it to 33% and so on.
Supercritical steam generator – Wikipedia
2019-10-24 · A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.Therefore, liquid water immediately becomes steam.
