What are the causes of damage to the steam superheater tubes behind the sulfur flue gas furnace? Let’s discuss it!
1. Product quality issues, or poor construction quality, resulting in damage； 2. Dew point corrosion of the heat exchange tubes by flue gas, resulting in bundle leakage ； 3. Operation at excessive temperature or pressure, resulting in equipment damage ；
What was said on the 2nd floor is very good. One more thing to add: it’s also possible that some of the pipes are blocked, resulting in uneven heating
The stability inside the furnace was not properly controlled, resulting in increased thermal stress in the superheater. Too much fuel gas was added
The quality of the steam is unsatisfactory, resulting in pipeline corrosion
