Regarding water accumulation phenomena
Thread Content
Does the drain line of the reboiler need to be kept slightly open during normal operation? Keeping it slightly open can cause water accumulation noises; can the drain line be closed to eliminate this issue?
If the strainer is selected correctly to meet the operational requirements and can function properly without failures, it is not necessary to activate the bypass line.
Generally, it should be left slightly open; it’s not good to turn off the bypass line.
If the selection is appropriate and the quality is reliable, it might not be necessary to have a secondary line
Consider adding a secondary line only after installing a trap; it’s likely that there’s a problem with the trap. Check whether the outlet temperature of the reboiler is stable; if it isn’t, it’s often due to an issue with the trap.
This can be prevented by using a strainer; there is no need to install a bypass line. The most important thing is to choose the right trap; does the poster mean that no trap is being used?
If the strainer is properly selected, has sufficient capacity, and is operating normally. The bypass line should not be used. If the capacity of the steam trap is insufficient, the bypass line can be employed, but this may allow steam to enter the condensate pipeline directly, thereby causing water hammer. Or steam leakage from the steam trap can also cause water hammer. Handle it according to the situation.
I’ve learned something! It’s necessary to learn about strainers!*
