What is one main purpose of using baffles in steam drums?

Using baffles in steam drums primarily serves the purpose of promoting water separation. Baffles are structural elements that help to control the flow of water and steam within the drum. They create turbulence that allows for better separation of water from the steam, ensuring that the steam that exits the drum is as saturated and free from water droplets as possible.

This process is crucial because the presence of water in the steam can lead to issues such as water hammer and decreased efficiency in the heat exchangers and turbines downstream. By optimizing the separation of water, the baffles contribute to the overall effectiveness of the steam-generating system, enhancing performance and safety.

While other options address different aspects of steam system operation, they do not directly relate to the primary function of baffles. Pressure management and fuel optimization pertain to the overall efficiency of the boiler or heating system but are not directly influenced by the presence of baffles. Similarly, ensuring complete combustion relates more to fuel-air ratios and combustion conditions rather than the role of baffles in the steam drum.
