Regarding the issue of false water level in the drum
Thread Content
1. Under what circumstances does a false water level occur? 2. How can one determine that it is a false water level, rather than being caused by a lack of water or an excess of water in the boiler? 3. How to deal with false water levels?
1. Starting up and shutting down the furnace, draining waste water, and repairing instruments can all cause false water levels. 2. Comparison of the computerized water level with the 19-point level gauge or the on-site level gauge. 3. Check the instruments promptly and resolve any faults; it is strictly prohibited to switch to automatic mode – operate manually until normal operation is achieved.
The following situations can cause a false water level: 1. The valve in the steam-water connection pipe of the water gauge is closed, or the steam-water connection pipe is blocked by scale or other debris. 2. Leakage in the gas connection valve. 3. Leakage in the water level gauge drain pipe. By flushing the water level gauge, it can be determined whether there is a false water level.
Is the poster referring to false liquid levels indicated by the on-site level gauge, or false levels shown by the instrument? False liquid levels at the site are indeed troublesome; I would like to ask experts for solutions and ways to avoid this issue
It’s in this connection! http://bbs.hcbbs.com/viewthread.php?tid=314175&highlight=%D0%E9%BC%D9%CB%AE%CE%BB
Steam carrying water can cause a false water level.
I learned it. Thank you. HaiChuan has learned a lot at school
I’ve also been thinking about how to solve this problem. Generally, it seems that this issue arises when starting the steam heating process and when adding water to the steam drum; at such times, a gas-liquid azeotrope is formed, resulting in the generation of large amounts of foam. If the internal structure of the steam drum can be changed, this phenomenon should be able to be mitigated
