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.
