Where is the steam drum located in a boiler?

The steam drum in a boiler is positioned at the top of the boiler. This location is crucial, as the steam drum serves as the central component in steam generation and separation. Its elevated position allows for efficient separation of steam and water; as water is heated within the boiler, it rises and accumulates in the steam drum, where steam is collected at the top. This design utilizes the natural tendency of steam to rise, ensuring that steam is drawn off effectively while minimizing the amount of water that escapes.

Moreover, having the steam drum at the top helps in maintaining the correct pressure and temperature for the generated steam, which is vital for the proper functioning of a steam system. The configuration also supports safety measures, as it reduces the likelihood of water carryover into the steam lines, which can cause damage or inefficiencies in the steam system.
