What happens when a boiler runs out of water?
Boiler Failure If a boiler has enough water, the steel will never reach temperatures high enough to weaken it. In a dry fire accident, there is no water to moderate the temperature. As a result, the boiler’s steel can overheat, warp and crack at the welds.

How do you stop a steam locomotive from scalding?
