In a catalytic reaction unit, if tail burning occurs in the regenerator and the temperature of the flue gas fan rises, which measure should be taken first? A. Reduce the butterfly valve at the inlet of the flue gas fan. B. Increase the main air supply volume. C. Significantly reduce the air flow. D. Inject oxygen into the regenerator for combustion
In the catalytic reaction unit, tail burning occurs in the regenerator, causing the temperature of the flue gas fan to rise. The first action that should be taken is (C): A. Reduce the butterfly valve at the inlet of the flue gas fan; B. Increase the main air flow; C. Significantly reduce the air flow; D. Inject oxygen into the regenerator for combustion
D. Oxygen consumption for combustion of fuel injected into the regenerator
In a catalytic reaction unit, tail burning occurs in the regenerator and the temperature of the flue gas fan rises; what should be done first? Should it be A. Reduce the butterfly valve at the inlet of the flue gas fan? B. Increase the main air flow? C. Significantly reduce the air flow? D. Inject oxygen into the regenerator to aid combustion?
Let’s learn this: first, we should close the butterfly valve at the inlet of the exhaust fan
Why such a significant drop in wind speed? Can closing the butterfly valve at the exhaust fan inlet be effective? Please explain it as well
