Operation status of loose air for FCC external heat exchanger
Thread Content
The unit is of the 120-coaxial type, and the 9 loose air intakes of the external heat exchanger have never been put into use (the management said it was to prevent the heat exchange tubes from being damaged by the airflow). I wonder what the status is of the units at your sites? What factors determine whether to put it into use or not?
Water vapor does not exist at 1 atmosphere pressure and 0 degrees Celsius. The density of water at 20 degrees is 998.203 kg/m3. The density of water vapor at 1 atmosphere and 100 degrees Celsius is 0.60 kg/m3. 1 cubic meter of water turns into saturated steam at 100 degrees: 998.203 kg / 0.60 (kg/m3) = 1663.67 m3
Haha, what’s going on on the second floor? :lol
The fluidization air is in use, but the loosening air isn’t?
We haven’t used it here yet, but it’s working just fine!
Is the fluidization air not being used either?
The fluidization air can be replaced with 2-inch power air; ensuring an adequate steam generation volume is sufficient!
Well, the fluidization air is kept operating to ensure the heat extraction rate for external heat removal.
Teacher, have you understood? I simply didn’t understand.
Is your fluidization working properly? Are there no areas where the material becomes loose, and has there been no occurrence of catalyst bridging inside?
