Why is it necessary to control the inlet temperature of the exhaust fan? How to check whether the electrical heating for instruments is working properly in winter? What to do when there is a significant difference between the liquid level at the external heat exchanger and the level shown on the DCS? How to analyze and determine the true liquid level?
Why is it necessary to control the temperature at the inlet of the flue gas extractor? Both the pipes at the inlet of the flue gas extractor and the extractor itself have temperature tolerance limits; exceeding these limits is harmful to the materials used and can lead to accidents. What happens when there is a significant difference between the liquid level measured on-site in the external heat exchanger and the liquid level shown by the DCS? How to analyze and determine the true liquid level? It’s not just this liquid level; if it cannot be determined, first ensure that the on-site level gauge is accurate, and then use the on-site liquid level to calibrate the DCS remote liquid level
