How to Destroy a Boiler -- Part 1

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.
