Regenerator dead bed time
Thread Content
Have you experienced bed fouling in your regenerators? What is the maximum duration of such issues? For us, it reaches up to 6 hours; the temperature of the regeneration bed goes up to 480 degrees at that point
We left it to stew for 1 day. The duration of the bed holding time depends mainly on whether it is possible to effectively cut off media such as air and steam from entering the regenerator.
The bed-soaking time depends on the ignition point of the diesel injected; with less heat loss, the time is relatively longer.
The regenerator is equipped with a heat-insulating and wear-resistant lining, giving it excellent thermal insulation properties. Moreover, catalysts themselves dissipate heat slowly. With good preventive measures, it should be fine to stay sealed in for a day.
The temperature in the area where each unit is located varies, and the time required for bed packing depends mainly on the temperature of the bed layer in the regenerator. As long as it exceeds the ignition point of the injected diesel, the bed can remain sealed.
Has it been this long since the bed became stuffy? 24 hours?
No problem. But the wind and steam must be completely removed; that’s essential.
The maximum time the bed can remain idle is 48 hours; in the regenerator, all systems are shut down except for the protective air supply to the oil combustion nozzles
