Recycling of steam condensate?
Thread Content
Our unit currently consumes a large amount of steam, and I would like to ask how to reduce this consumption. Thank you. If the steam in our facility is to be used for heat tracing, we have currently tried reducing losses by lowering the opening degree of the drain valves, but this approach has not been very effective. (Our facility does not recycle its condensate water; it is discharged directly, which results in some waste.) Do anyone have any suggestions? For example, in the case of steam condensate, do many organizations recycle it back to the boiler room to use as water for the boilers? The advantages of doing this are twofold: it allows for the recovery of condensate, and it also helps to retain some of the heat, thereby reducing energy consumption.
For heat exchange, it is recommended to use a condensate tank instead of a steam trap; it is more effective. Consider installing a low-pressure flash tank to recover low-pressure steam for use as heating energy； It is important to choose a reliable heat-traced trap; just because it is expensive does not mean it will be effective. Testing is necessary, including measuring temperature to check for air leakage. If the condensate is to be reused, measures to remove salt and iron are required, and it is necessary to consider whether this is cost-effective.
A relatively closed-loop circulation for steam is already the basic energy-saving principle in this industry; it is necessary to restructure the process and optimize the heat exchange network.
:o If it is process condensate, it is recommended to add a condensate recovery system
Our facility has an independent water recovery system; the condensate is directly returned to the intermediate water tank, and steam is also utilized step by step.
Then use a system for condensate recovery, oil and iron removal, and then reuse it as demineralized water
The condensate is sent to the deaeration tank to continue generating steam.
It is recommended to add a condensate recovery system
The condensate from our company goes directly into the recirculation tank, reducing the use of fresh water
All of it is recycled; after rust and iron removal, it is used for filling boilers or as deoxygenated water in temperature and pressure regulators
