High-Pressure Feed Water & Condensate Collection Container
In this closed system, the condensate is not relieved, but is fed into a condensate pressure vessel.
The JUMAG High-Pressure Feed Water &
Condensate Collection Container:
Function and Benefit
What is the high-pressure feed water container used for and what are its advantages?
Difference from the classic feed water container
In most steam systems, the condensate is completely relieved and returned into a depressurised feed water container. Relaxation steam is released when condensate is relieved. The energy contained within will be lost depending on operating method. This may make up as much as 15% of the total energy demand. Because of the relaxation steam, water is lost from the steam cycle on the same scale.
With the high-pressure feed water container, on the other hand, the condensate is not (or only partially) relieved. Instead, it is fed into a condensate pressure container. In this way, the energy and water are utilised, which would be lost if relieved through relaxation steam.
Of course, the high-pressure feed water container offers all the functions of the classic JUMAG feed water container.
The high-pressure feed water system proves particularly useful for steam systems …
- with a high share of condensate return flow (if possible 100%). The higher the share of condensate return flow, the higher the savings as compared to a depressurised feed water container.
- with steam consumers, all of which emit condensate at a high pressure (at least >1bar, if possible >4bar). As the condensate pressure vessel may at most have the pressure of the lowest condensate return flow, there should be no consumers with low pressure.
- with high condensate temperatures (if possible in excess of 110°C). The higher the condensate temperature, the higher the savings as compared to a depressurised feed water container.
- with long operating times. With regular use of the steam system, the pressure in the condensate pressure vessel can be maintained and the system will run stably.
