Optimizing the thermal efficiency of an installation consists in optimally recovering the energy that would otherwise be lost (fatal heat). A water preheater makes it possible to recover the heat contained in the condensates before storage.
Thermal Specificities
Quiri, as a specialist of
heat exchangers, can provide you a
water preheater.
Device delivered in France in 2020 as part of the construction of a Waste Facility
The
preheater supplied by Quiri is part of a batch of 3
heat exchangers: a
water preheater, a
vaporizer and a
steam superheater.
The Quiri thermal design
heat exchanger preheats superheated water from condensates from an upstream turbine.
