Shell and tube heat exchangers, hydraulic cylinders, components & hydraulic systems, gas springs : Quiri

Condensate reheater

Industries concerned : 
Product concerned : Shell and tube heat exchangers
Condensate reheater - Shell and tube heat exchangers - Quiri
At a time when all thermal systems ensure maximum efficiency, condensate heaters allow maximum energy recovery and thus contribute to climatic issues.

Thermal Specificities:

  Quiri, as a specialist of heat exchangers, can provide you a condensate reheater / vapour condenser   Equipment delivered in England in 2018, as part of the manufacturing of a waste facility combined with a power plant. The project will be able to generate up to 43MW per year of electricity from the incineration of household waste for the region and provide steam for a paper mill. The condensate reheater supplied by Quiri is part of a set of 4 heat exchangers: two condensate reheaters, one feedwater heater and one dearator vapour condenser. The function of these shell & Tubes exchangers is to reheat condensates from the steam coming from the upstream turbine. The heat exchanger, of Quiri thermal design, condenses the steam with an integrated sub-cooling system of the condensed steam.
