recuperator

[rē′kü·pə‚rād·ər]
(engineering)
An apparatus in which heat is conducted from the combustion products to incoming cooler air through a system of thin-walled ducts.

Recuperator

 

a surface heat exchanger for recovering the heat of waste gases, in which the heat exchange between the fluids occurs continuously through a wall. In contradistinction to a regenerator, the paths of the fluids do not change.

On the basis of the relative motion of the fluids, recuperators can be classified as counterfiow or parallel-flow. According to design they can be classified as tube, film cooler, thermo-sy-phon, or other type and according to use as preheaters of air, gases, or liquids, evaporative coolers, condensers, and so forth.

Over the last decade, GTI project staff (formerly with Aerojet Rocketdyne) established a leadership position in sCO2 technology with work in cycle modeling and optimization, economic evaluations, advanced materials characterization, and design studies of key components (such as turbines, compressors, and recuperators.
The recuperators capture energy normally lost to the atmosphere and re-circulate it back to the process, resulting in significant fuel savings.
