What is the main purpose of a steam drum in a boiler system?

• A. Store and separate steam from water
• B. Preheat feedwater
• C. Reduce pressure
• D. Control temperature

Answer: (A)

The main purpose of a steam drum in a boiler system is to store and separate steam from water. In a boiler, water is heated to produce steam, and the steam drum serves as a crucial component where this separation occurs. The drum collects steam generated from the boiler water, allowing it to rise to the top while the water remains at the bottom. This separation is essential because it ensures that only fully saturated steam is delivered to the steam header, thus optimizing the efficiency and safety of the steam system. The steam drum also helps maintain water levels and provides a buffer for changes in steam demand, ensuring consistent steam production. Additionally, by allowing steam to accumulate, it facilitates the removal of impurities and excess water droplets that could carry over into the steam delivery system.
