The purpose of a steam separator in a boiler system is fundamentally to remove moisture from steam. In a steam system, it is essential to produce dry steam because the presence of moisture can lead to various operational problems and inefficiencies, including corrosion and damage to steam equipment.

When steam is generated, it can contain small droplets of water, creating a mixture known as wet steam. A steam separator efficiently works by using centrifugal force or baffle plates to cause the moisture to collect and drain away, allowing only dry steam to pass through. This ensures that the steam used for heating, powering turbines, or other applications is as pure and dry as possible, optimizing performance and safety in the steam system.

The other options do not align with the primary function of a steam separator. Increasing steam pressure pertains more to boiler control mechanisms rather than separation. Separating different steam qualities may refer to distinguishing between superheated and saturated steam, which is not the central role of a separator. Releasing excess steam pressure relates more to pressure relief valves and safety devices, not the function of separating moisture from steam.
