There’s a lot of contributing factors to problems in the transfer linings.  How old is your unit?  They just wear out over time. 
 
One thing your operators can do is control the temperature swings.
 
Some of it’s rocket science, and other methods are easy.  For example during the cooldown, GO SLOW.  When starting back up, GO SLOW.  Raise the temperature gradually. Have your engineer make recommendations, but you’ll probably want to keep the catalyst under 500 degrees celsius.
 
Hope that helps next time,
