What is a function of the steam drum in a boiler?

The function of the steam drum in a boiler is to collect and separate steam from water. In a boiler system, water is heated to produce steam, and the steam drum serves as a crucial component where this separation occurs. The drum allows for the collection of steam that rises to the top as water remains at the bottom.

In addition to separating steam from water, the steam drum also plays a role in maintaining water inventory and ensuring that the steam produced is of high quality by allowing impurities to settle. This quality control is essential for the efficiency of the steam cycle and the protection of downstream equipment, such as turbines.

Overall, the steam drum is integral for the efficient operation of a boiler, facilitating the movement of steam while providing a space for water management and separation processes.
