Synonyms: waste heat utilisation, waste heat recovery unit, WHRU
The process of harnessing the heat generated by power plants or industrial machinery, which would otherwise remain unused, in order to alleviate demands on energy generation.
A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that recovers heat from hot streams with potential high energy content, such as hot flue gases from a diesel generator or steam from cooling towers or even waste water from different cooling processes such as in steel cooling.
