Try NFPA 33.  It is for Spray Application Using Flammables.

Subject: sprinklers in duct

I am doing a system for a spray booth and the associated exhaust 
ducts. I can't seem to find the section of the NFPA standards that 
references this. NFPA 91 says provide sprinkler protection without 
any further guidance. NFPA 13 chapter 7 talks about cooking equipment 
and it's ductwork, but doesn't give many specifics. Seems to me there 
is something about having sprinklers within 3 ft of where the duct 
exits the building, but I can't find it. Anybody know where this 
stuff is off the top of their head?
