What does recuperator mean?
A recuperator is something that restores or recovers what would otherwise be lost. In general usage, the word can denote a person or thing that repairs, recovers, or restores something. Its established technical meaning refers to a heat-recovery device: a recuperator captures heat from exhaust or waste gases and transfers it to incoming air or another fluid, often in an industrial furnace or turbine system. The term is relatively uncommon in everyday English but useful in engineering and energy discussions. Its association with recovery is especially vivid in the technical sense, because the device captures otherwise wasted thermal energy and makes it productive. The word can consequently be understood as a literal heat restorer, while its broader meaning preserves the older idea of someone or something that brings something back to a sound or effective condition.
nounA recuperator is a person or thing that recovers or restores something. In engineering, it is a heat exchanger that transfers heat from outgoing exhaust or waste gases to incoming air or another fluid.
- A person or thing that recovers, restores, or repairs something.
- An engineering device that recovers heat from exhaust or waste gases and transfers it to incoming air or another fluid.
"The recuperator uses the exhaust heat to warm the incoming air before it enters the furnace."
"The recuperator recovered enough heat from the exhaust to improve the plant's efficiency."
"He was a determined recuperator, gradually restoring both his strength and his confidence."
The usual plural is recuperators.
"The plant's recuperators recover heat from the exhaust stream."
A recuperator rescues waste heat and turns it into useful warmth instead of letting it escape.

Etymology of recuperator
The word comes from Latin recuperator, meaning "one who recovers" or "restorer," which was formed from recuperare, "to recover, regain, or restore." The English word developed from that Latin noun and retains both its general sense of restoring or recovering and its specialized sense of a device that recovers waste heat.
