Thermal physics - bizarre question of the day.

Hi all,
Hopefully you may be less bemused about this than I am.

Say I had a container with sufficient air within to keep some coals red
hot; otherwise the container is sealed.
Around this container is another container, longer with an open top:
the
container with the coals is already under water. Now say I poured ice
cold water into
this outside container through the open top, and, for various reasons,
the inside container fractured, allowing the water and coals to meet.
Would you feel an uprush of hot water (or whatever) at the top of the
open container?
Or would the water have quenched any hot "blast" completely?

The reason is as follows (sorry for the convoluted explanation): when
the Titanic was sinking, the boiler
rooms flooded, and the boilers, although not water tight, still
contained hot coals. Right at the top of the boiler
room were "fidleys", air vents that went up to the boat deck, about 30
metres above. When the ship was
going down, water rushed down these fidleys, into the boiler room, and
one man found himself pinned against
the gratings above the fidleys. He was eventually released by a gust of
hot air/water from below that allowed him to escape.

Best wishes

Paul
