old steam boiler explosions
As I think about the explosions of old steam boilers, I know through the Dead Men's School, that these incidents ocurred when a boiler was burning coal and water was added to the dry burning boiler. Steam expands to 1700 times the volume of water, but what I'm trying to clarify is what is actually happening at the time of the explosion, scientifically? How hot is the boiler getting? How much water does it take to initiate this reaction? Can you have an explosion without adding water? I'm trying to get the science of these boiler explosions clarified. Can anyone help me out with this? Thanks!
