5.2.5 Steam Rankine Power Stations
22.214.171.124 Reheating-Regenerative Steam Rankine Cycle
The vast majority of power stations are based on reheating-regenerative steam Rankine cycles. These types of cycles are very complex as they comprise many types of components, including preheater, boiler, superheater, reheater, closed (CFWH) and open (OFWH) feedwater heaters, mixer, condenser, deaerator, pumps, and steam traps (ST). The cycle design depends on the type of heat source and heat sink. For most cases of large power generation the heat source is derived from coal combustion.
The heat sink is in general a lake; however, there are many cases in which power plants use air as a heat sink. In this case the plant is equipped with cooling towers—either with ...
