Open or closed steam condensate system
Steam condensate systems can be open or closed. In open systems, after the condensate drain, condensate enters the condensate collection tank, which is connected to the atmosphere and is not under excess pressure, and then is pumped into the boiler room with the help of a pump. In this case, the temperature of the condensate in the tank is about 100 ° C.
The advantage of such a system is a lower initial investment, as well as ease of installation.
In closed condensate recovery systems, the condensate does not come into contact with the surrounding atmosphere, in such systems it is under pressure during the entire recovery process, therefore its temperature can be significantly higher than 100 ° C, and this saves energy for heating the condensate and, most importantly, eliminates the loss of secondary steam.
Conditions for choosing the type of system
Two indicators are used to select a system:
- condensate recovery factor
- condensate pressure
Pivot table
| - | Open system | Closed system |
|---|---|---|
| Maximum condensate return temperature | 100 ° C | 180 ° C and above * |
| system configuration | Simple | Complex |
| Initial costs | Low | High |
| Energy efficiency | Depends on the system (losses increase with increasing steam condensing pressure) | Maximum |
| Corrosion of pipelines | High (condensate comes into contact with air) | Practically absent |
| Loss of secondary steam | Large amount (increases with increasing steam condensation pressure) | Practically absent |
| Chemical consumption prepared water | High | Minor |
* Limited by the maximum operating temperature of the pump and fittings
