The main function of the mud drum in a boiler is to collect sediment and impurities. In a steam boiler, especially in water tube boilers, the mud drum serves as a reservoir at the bottom of the system where heavier particles, like sediment, scale, and other impurities, settle out of the water. This is crucial for maintaining the efficiency and longevity of the boiler, as accumulated debris can affect heat transfer and lead to corrosion or other operational issues.

By ensuring that these contaminants are removed from the circulating water, the mud drum plays a vital role in the overall health of the boiler's operation. This collection process helps maintain water quality within the system, thereby preventing issues that can arise from poor water conditions, such as foaming or carryover of impurities with the steam. In contrast, facilitating steam generation, regulating boiler pressure, and reducing energy loss pertain to different components and functions within the boiler system.
