What’s the use of the air line connected to the fuel burner nozzle?

There is already misty vapor; why is a air stream still needed?
When no oil is being sprayed, use air to protect the nozzle
When not in use, use air to blow in the reverse direction to keep the nozzle unobstructed
Steam is used for atomization, while air is used for purging; introducing steam into the regenerator can cause thermal collapse of the catalyst!
When spraying burning oil, should the wind be turned off? Thank you
When spraying combustion oil, use steam to atomize the diesel; after spraying, turn the air supply on to prevent the catalyst from blocking the nozzle holes!
Nonsense – the air stream is used to prevent the nozzles from clogging at the start of operation. Under normal conditions, whether the bed temperature is increased during operation, maintained during shutdown, or when carbon production is low and the bed temperature is low, the combustion oil is atomized using steam; air is only used to prevent nozzle clogging when starting up the reactors； :Q
After spraying, the cleaning process produces steam, and under normal conditions this steam is allowed to enter the regenerator in excess; that’s how our system works
It’s fine to let steam in; the amount isn’t large, so it won’t be as problematic as you say, and there’s no chance of thermal failure
I agree with you; catalysts aren’t as fragile as people think – a little bit of steam can cause thermal degradation of the catalyst
