A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid … See more The first regenerator was invented by Rev. Robert Stirling in 1816, and is also found as a component of some examples of his Stirling engine. The simplest Stirling engines, including most models, use the walls of the cylinder … See more Regenerators exchange heat from one process fluid to an intermediate solid heat storage medium, then that medium exchanges heat with a second process fluid flow. The two … See more The major disadvantage of rotary and fixed-matrix regenerators is that there is always some mixing of the fluid streams, and they can not be completely separated. There is an unavoidable carryover of a small fraction of one fluid stream into the other. In the rotary … See more The advantages of a regenerator over a recuperating (counter-flowing) heat exchanger is that it has a much higher surface area for a … See more • Countercurrent exchange • Economizer • Heat exchanger See more • Butz, J.
