In sulfuric acid production plants, the liquid level in medium-pressure boilers is controlled at 60% in some plants. Some factories keep it at 50%. What are the differences between these two types of boilers?

Is the boiler level control that precise? Generally, a level within the range of 30-70 is sufficient; of course, it’s better if the control can be that accurate
Yes, we keep the variation within 3 percent
Under normal conditions, we keep it at 50%; in cases of thunderstorms or power supply changes, we set it at 60%. The main reason for this is to prevent a dry-boiling accident caused by the pump stopping due to a power outage. If it is kept at 60% for an extended period, there is a risk of foaming due to pressure fluctuations in the steam pipeline network, which could result in steam carrying water and thereby damaging subsequent equipment.
Haha, we keep it around 55% here on a daily basis, taking into account the points mentioned above. Furthermore, sulfur-based acid production boilers are relatively small in size and have limited redundancy, so it is necessary to properly control the boiler’s liquid level, taking into account both heat extraction and safety considerations!
