Boiler Steam drum internals and function
Steam drum internals for typical type of boiler are shown. The internals include separation devices to assist in separating small droplets of boiler water from the steam. Boiler water in the steam will cause scaling of the superheater and steam turbines.Baffles, chevron types separators and demister pads are used to minimize boiler water carryover.

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.

Steam Boiler: Separation Process in Steam Drum
Steam has less density than water so steam will go to the top of drum and water will fall to bottom of drum. This separation process depends on the location out of steam and water, the speed and position of the incoming steam, the quality of steam and so on. But the natural separation process has some …

List of Steam Boilers: Types, Parts and Operation
The superheater is placed in the combustion chamber just under the steam and water drum. It consists of a number of U-tubes secured at each end to horizontal boxes. Steam formed in the boiler is led to the upper box of the superheater by a vertical T-tube placed in the steam space of the drum.

Water Tube Boilers - Spirax Sarco | First for Steam Solutions
Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5). Cooler feedwater is fed into a drum, which is placed longitudinally above the heat source. The cooler water falls down a rear circulation header into several inclined heated tubes.

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
