Condensate recovery
Thread Content
Regarding the steam condensate recovery station shown in the diagram, the main pipe runs from a height of 0.6 meters upward to pipes located in a duct at a height of over 4 meters. Can the liquid be forced back using pressure? Will it freeze in winter?

Whether it can return smoothly to the pipeline depends on whether the recovered condensate has a static head sufficient to reach a certain height. Whether condensation in the pipes freezes in winter depends mainly on where your factory is located and whether adequate insulation has been provided for the condensation pipes to protect them from the climate conditions. If you are in tropical provinces such as Hainan, Guangdong, and Guangxi, then you need to check whether the water freezes in winter there Perhaps you haven’t experienced winter at the factory yet.
Most steam heaters are equipped with control valves; even if the system backpressure increases and prevents the condensate from flowing, the control valve will open automatically to increase the pressure behind the valve and thus allow the condensate to be discharged. The main steam pressure must be greater than the system backpressure; otherwise, the design is unreasonable.
The condensate recovery station also has a certain pressure; otherwise, the water would be discharged on-site.....
