Which component is critical in dampening the motion of water in a steam drum?

• A. Manifold
• B. Swash plate
• C. Venturi
• D. Heat exchanger

Answer: (B)

The swash plate is a critical component in dampening the motion of water in a steam drum because it directly interacts with the water surface and helps to stabilize the liquid. In a steam drum, there's often turbulent water due to the boiling process and the generation of steam. The swash plate functions by creating a controlled surface action that breaks up waves and oscillations, minimizing the violent motion that could lead to water carryover into the steam lines. This is crucial because carryover can cause damage to turbines and other downstream equipment, as well as affect the efficiency and stability of steam generation. In contrast, a manifold primarily serves to distribute steam or water; it doesn't actively dampen motion. A venturi is designed to measure flow rates or create a pressure differential, not specifically to manage liquid motion. A heat exchanger's main function is to transfer heat rather than to control water turbulence in a steam drum. Thus, the swash plate's specific design and role make it the most effective at reducing unwanted movement in this context.
