Installation problems of heat exchange tubes in economizer for sulfur acid production
Thread Content
Hello guys, this economizer heat exchange tube has high temperature, medium temperature and low temperature heat exchange sections from top to bottom, all arranged in an equilateral triangle. I would like to ask if the medium and low temperature heat exchange sections are arranged like "//////". Why are the heat exchange tubes in the high temperature heat exchange section arranged like "\--/\--/\--/\--/"? Thank you.
Increase resistance and extend heat exchange time
consult: Is it a finned tube? It increases the resistance. How to solve the scaling problem? Dew point corrosion? Thanks
I'm a newbie and don't need to ask for advice. . After discussion, there will be dew point corrosion in the low temperature section, which will have a great impact on the service life. It is necessary to make a casing outside the heat exchange tube, or use the heat pipe directly.
