There has been a lot of foam in the boiler blowdown recently. I don't know how it will affect the liquid level and how to solve it.
Reply 1# hjlm Recently, there is a lot of boiler blowdown foam, which is easy to form false liquid levels and form vapor-liquid azeotrope on the vapor-liquid interface. How to solve it depends on the analysis of the specific situation. If there is a detailed introduction, we can discuss it.
Liquid level solution causes false liquid level, how to deal with it: Check whether there is any problem with the boiler water quality. If there is any problem, contact the previous process to solve it. ； In addition, sewage discharge can be increased.
Excessive foam will cause false liquid levels, and the amount of discharge should be increased to prevent the pot from drying out. And analyze the water quality. Is there any leakage in the middle pot?
Excessive foam will definitely interfere with the liquid level detection and control of the waste pot. In this case, pay close attention to the gas phase outlet temperature. To avoid unnecessary accidents. I guess it's a water quality problem. Improve the water quality and increase the amount of sewage discharge.
First improve the water quality, if not harmful check the process operation.
