Timkin, you right about the boiler explosion story, only had their been one in a boiler that big we would be dealing with a new building, and some scared trees. Not only that but damage in neighborhood buildings, chunks of Annie weighing 5-6,000 pounds embedded in nearby houses, streets etc.. One thing is certain, the chance that they rebuilt a boiler that exploded without reconstruction is about zero.
At the risk of being redundant I'll point out a basic law of steam engineering that really should be familiar to everyone that owns a house, pressure cooker, or water heater:
In a pressure container (boiler) boiling water and steam occupy a restricted space and cannot expand, this is where all steam power comes from, IE: pressure. When suddenly exposed to atmospheric pressure the steam will instantly expand 10,000 times. Imagine the bomb just a coffee cup could create is it could be pressurized! The other way to meet your maker is to take the boiler up to 966+ F, at this temperature all of the water molecules will convert to gas and you've got problems, though you'll probably never know it!
Hope this sheds a little light on the story, perhaps we should take a hard look for signs of a rebuilding? I doubt it seriously, had students been present the death toll could have been staggering, and I'm certain the story legendary.
