You have no standard to go by for this and no design criteria to apply. There are so many variables to deal with here since steam comes in so many different compositions depending on application rates and temperatures, how far from the boiler will the steam have to travel to the hazard, what is the temperature and pressure at the delivery point, condensation rate, etc., etc., etc...........
Steam is nowhere near the same as water mist. If he insists on this approach then he needs to hire a qualified ME/FPE to do the analysis and make the application rate determinations based on the condition of the steam and the hazard. Then try to sell it as an alternative to the AHJ. This is like stepping into a snake pit. BEWARE and AVOID at all cost. Craig L.

An owner of a manufacturing facility (I don't know what type of manufacturing) has in his head that he wants to use steam from his boiler for fire suppression (also don't know what he wants to protect). I am basically looking for any information on using steam for fire suppression. I have no experience with this and haven't heard of it beyond steam smothering systems for kitchen exhaust ducts?? Is that still used? I am somewhat familiar with water mist systems but this sounds like a different animal because we would be "delivering" steam to a fire not forming steam when water droplets turn to steam at the fire. Doesn't seem practical or even possible to me. Sorry for the lack of information but that is all I have to share. Thank you for any info. you have. Reed A.
