Steam drum - Wikipedia

A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.

Carry Over From Boiler Drum - Bright Hub Engineering

Oct 10, 2009 · Carry over from drum can be of two types: mechanical carry over and vaporous carry over. The carryover from boiler drum results in deposits in the internal surface of superheater tubes leading to overheating failures. It also results in deposit in turbine blades which reduces the turbine efficiency. Mechanical carry over take place in a boiler mainly due to drum internals; drum level, foaming
