Adjustments for boiling up caused by a sudden increase in the steam generation rate from the drum
Thread Content
Due to fluctuations in the operation of the external heat exchanger, the steam generation rate from the drum decreases before suddenly increasing, causing the drum to appear to be at full liquid level momentarily. How should this be adjusted?
Is the three-element control not in service? The main concern is that steam carrying water may cause temperature changes in the rear superheater, leading to equipment damage!
Showing a full liquid level isn’t accurate, right? Can using three-injection control solve the problem of boiling overflow?
Prevent false level indications, with on-site reference glass plate
1. Control the water supply amount to match the gas generation volume. 2. Adjust operations smoothly on-site by referring to the glass plate in a timely manner.
It’s not necessarily a guaranteed solution, but such problems can be resolved fairly well; there are algorithmic settings in place among the three elements!
