Regenerator lean phase temperature
Thread Content
I have designed the regenerator in the form of a pre-coking vessel; the dilute-phase temperature of the regenerator increases by 10–20 degrees each time a dose is added, and sometimes by 30 degrees. Please ask fellow sailors to help answer!
If it is added directly to the regenerator, it may be the result of bed disturbance. If tail burning occurs regularly, has the combustion aid been changed?
The oxidizer has remained unchanged, while the catalyst is added to the coking tank
This is normal! The additive and the unpurified air used are much cooler than the main air, resulting in secondary combustion; reducing the dosage and the time used will help solve this issue
But we have two small dosing systems, and one of them is particularly effective – it can reach temperatures of over 20 or 30 degrees
Yes, is it related to some catalyst?
Right! Different catalysts also have varying effects on combustion promotion
But they are all main components, not combustion promoters!
Catalysts also have a combustion-promoting effect! It’s just not as good without an oxidizer
