Reasons for fluctuations in the dilute-phase temperature of the catalytic regenerator
Thread Content
Reasons for fluctuations in the dilute-phase temperature in the catalytic regenerator: In my unit, there are significant fluctuations in the dilute-phase temperature at the inlet of the first-stage centrifuge in the regenerator, with fluctuations ranging from 20 to 30 degrees. The fluctuations are especially noticeable at the centrifuge inlet. Please help analyze the reasons; thank you! !
What is the state of the dilute-phase density? Are they regular fluctuations or irregular fluctuations? Are there any changes in the regenerator operation parameters compared to before the fluctuation? Has the flow rate of the regenerator, especially the dilute-phase loosening air, increased compared to before? When was the last maintenance of the centrifuge? Has the lining or the turtle shell mesh fallen off?
The density remains unchanged and is stable. The lining has also been checked, with no signs of peeling
The temperature also changes when the main air flow rate remains constant. To prevent the regenerator temperature from rising too high, it is necessary to reduce the main air flow rate when the temperature is high
It mainly depends on which side the higher temperature fluctuations occur in Nishisho Or are they all fluctuating?
