Waste Heat Recovery
A Waste Heat Recovery Unit or WHRU is a heat exchanger that recovers heat from a
hot gas stream. The hot gas stream can be the exhaust gas from a gas turbine or
a diesel engine or a waste gas from industry or refinery. The WHRU working
medium can be water, either pure or with TEG added, thermal oil or other
heating mediums. The aim of the WHRU is to recover the heat in the waste gas
and transferring it to the working medium which again is heat exchanged with
the goal fluid. A common application for a WHRU is for heating of other fluids
as oil or other process streams and is extensively used in oil-related
industries.
