Description of Steam Drum
A steam drum is a pressure chamber of a steam boiler located at the upper extremity of steam boiler circulatory system. It is a reservoir of water/steam at the top end of the water tubes. The steam drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. Steam is separated from the water and then discharged at a position above the water level maintained there.
Classification of Steam Drum
| Pressure | Low | Middle | High | Superhigh |
| Inner diameter(mm) | ￠ | ￠ | ￠ | ￠ |
| Thickness(mm) | 16-25 | 32-46 | 60-100 | 80-100 |
| Material | Carbon steel | Carbon steel & Alloy steel | Carbon steel & Alloy steel | Alloy steel |
Efficient steam-water separation factors of Steam Drum
1. It prevents the carry-over of water droplets into the superheater, where thermal damage could result.
2. It minimizes the carry-under of steam with the water that leaves the drum, where this residual steam would reduce the circulation effectiveness of the boiler.
3. It prevents the carry-over of solids. Solids are dissolved in the water droplets that may be entrained in the steam if not separated properly. By proper separation, this prevents the formation of deposits in the superheater and ultimately on the turbine blades.
**carry-over is the passing of water and impurities to the steam outlet.
**The term critical pressure is the pressure at which there is no difference between the liquid and vapor states of water; i.e., the density is identical. This occurs at 3206 psia.
