Methods for dealing with blocked boosters

This post was last edited by qiwu9981 on 2012-9-16 22:49. What other solutions are there when it’s severely blocked? Stop using it and clean it up; prevention is key in normal times! Flush the booster regularly to prevent urine from filling it up; there are signs before blockage occurs. If something is not right, alternate between flushing the separator, the throat tube, and the booster for a longer period of time; if the issue isn’t severe, things will improve and the condition can be maintained for some time, until scheduled shutdown when a thorough cleaning can be carried out. We’ve encountered it; this will work

Regular maintenance, with a focus on prevention； Planned maintenance.

I have experienced this too; there isn’t really a good solution – just be careful during operation to prevent liquid from entering the gas phase, and don’t turn off the steam from the booster. Additionally, disassembly, inspection, and cleaning are essential when parking. I have wondered whether changing the inner wall of the booster could effectively improve this phenomenon; I hope everyone will actively discuss it.

When operating the timed booster pump, the gas phase tube, and the two-stage heater, it is necessary to control the temperature and the vacuum level in the second stage carefully. It may also be helpful to keep the amount of urine as high as possible.

Pay attention to maintenance regularly and rinse often.

The pipelines of the evaporation system, including the two-stage separator and condenser, must be regularly flushed as part of a established routine, and operating procedures for flushing each component should be established; measures should not be taken only when blockages occur. Only in this way can a high vacuum level be maintained and blockages prevented.

Only through regular flushing can the high smoothness requirements for the inner wall of the booster be met; altering the structure of the inner wall might pose problems in allowing supersonic exhaust of secondary steam from the booster

Hehe, check the operation records – was the booster flushed on schedule? Additionally, sometimes poor coordination in delivering materials by vehicle, overfilling, or frequent changes in load can also cause blockages.

The booster should be rinsed with condensate at regular intervals, both before and after. Our company requires flushing every 2 hours or so, and we use steam at 0.3 MPa for our pressure boosters. Adjust the temperature and vacuum level according to the load conditions.

Does the booster play a significant role in the two-stage evaporation system? It seems like the booster here isn’t working

The importance of the booster pump does not lie in its function alone; what’s crucial is the temperature of the circulating water and the production load. When the temperature of the circulating water is low, it’s possible to achieve a good level of vacuum without using the booster pump. Sometimes, even at a circulating water temperature of 25–27 degrees and with a load of around 80%, it’s still possible to obtain a satisfactory vacuum level without using the booster pump. However, if both the circulating water temperature and the load are high, then it may be necessary to use the booster pump. Additionally, if the vacuum level in the first stage is good, there will be less light component in the second-stage evaporator. With less gas volume, the resistance encountered when the gas passes through the booster pump is also reduced, so it might be feasible to avoid using the booster pump in such cases. In reality, it’s best to adjust the use of the booster pump based on the actual vacuum level achieved.

In summer, the temperature of our circulating water is 28°C; currently it’s 22°C. The booster switch doesn’t work at all. Now we use the steam from the booster to control the pressure in the low-pressure tank. There’s little low-pressure steam being delivered these days; there’s no use for it!

Well, that makes sense; we removed the booster during the renovation this year.
