Chemical Treatment Requirements for Steam and Hot Water …

For example, a steam drum that is operating at normal water level has the bottom half of the drum cooled by water and the top half by air initially and steam eventually. If one starts to fire the boiler from a cold start, the water will heat up very quickly in the drum and the bottom half of the drum will expand much more quickly than the top half which is not in contact with water.

How Power Plant Boiler Works? - Bright Hub Engineering

A steam boiler has an interface of steam and water in the steam drum, which is where the water is finally evaporating due to the heat input, usually oil-fired burners. When a water tube fails due to any of a variety of reasons, it causes the water in the boiler to expand out of the opening into the furnace area that is only a few psi above atmospheric pressure.
