Inlet temperature of catalytic hood
Thread Content
My device is not completely regenerated. The inlet temperature of the hood is controlled at about 650 degrees. Is this low? If it is a lower temperature, I want to increase the inlet temperature, but the inlet of the regenerator cyclone separator will overheat to more than 730 degrees.
This temperature is a bit low. It is said that 660~680 is the optimal temperature. Lanzhou hood information says that the applicable temperature range is 620~700. However, if the temperature is lower than 660, the catalyst will tend to easily scale on the rotor.
The previous set of catalysis we had here was not completely regenerated. After checking, the basic temperature was only around 640°C!
I think as far as the poster’s current installation is concerned, this is a balance point. The regenerator temperature does not exceed the temperature. The higher the hood inlet temperature, the better. My personal opinion.
