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.
