(redirected from recuperators)
Also found in: Dictionary.


An apparatus in which heat is conducted from the combustion products to incoming cooler air through a system of thin-walled ducts.



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.

The final modification we selected was the use of a re-compression Brayton cycle, which uses two recuperators and splits a fraction of the flow.
The gensets will require recuperators to enhance fuel economy; the constant-speed range-extender turbines are unrecuperated for simplicity, reliability and low weight.
Analogical experiments were fulfilled with different recuperators with different requirements for the airflow rate capacity.
The compressor section raises air pressure to about four atmospheres and the air then enters a recuperator that preheats the air using turbine exhaust.
Each set of 20 Fushun retorts shares one condensing and cooling system equipped with two recuperators (one at combustion, one at heating), two gas blowers (one at work, one standby) and two air blowers (one at work, one standby).
Desuperheaters and heat recuperators can be fitted to the chillers when there is no need forchilled and heated water simultaneously.
Desuperheaters and heat recuperators for heat recovery can be fitted across the range, when there is a need for chilled and hot water at the same time.
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.
