Ed, good points we've kicked around as well. This chamber is only 250F, but the 80 psi is more than the available supply. Boom is not good unless it's the 4th of July or New Years.

Chamber could go boom. Of course the high steam pressure would stop sprinkler discharge Decisions on conditions like this are above my pay grade.
