What are the two types of drums found within a boiler?

In a boiler system, the two primary types of drums are the steam drum and the mud drum. The steam drum is located at the top of the boiler, and its main function is to separate steam from water. As water is heated and converted into steam, the steam rises to the top and collects in the steam drum, while the remaining water (along with any impurities) settles down into the mud drum.

The mud drum, situated at the bottom of the boiler, collects sludge, sediment, and other impurities that can accumulate as a result of the boiling process. This design allows for effective separation and ensures the clean and efficient operation of the boiler. Regular maintenance and cleaning of the mud drum are essential to prevent buildup and maintain optimal performance.

In contrast, the other options presented do not accurately describe the primary functions or common terminology used in boiler systems. Thus, understanding the role of the steam and mud drums is crucial for anyone involved in boiler operation and maintenance.
