🔍 Key Concepts

• Automatic feedwater regulator operation and what it responds to in normal conditions • Difference between mechanical failure in a control valve and normal process variations (like temperature changes) • Effect of foaming and high solids on level measurement in a steam drum

💭 Think About

• Ask yourself which option would cause the indicated water level to jump up and down without a smooth, stable pattern. • Consider which conditions would interfere with the regulator’s ability to sense the TRUE water level versus just changing how much water the boiler needs. • Think about whether a slow, steady change in feedwater temperature would cause ERRATIC level swings or just shift the setpoint slightly.

✅ Before You Answer

• Identify which choice directly affects the accuracy of level indication rather than just the actual level demand. • Distinguish between a faulty control component and a normal operating condition, and decide which is more likely to cause unstable, hunting behavior. • Consider whether foaming/high solids makes the level appear higher or lower than it really is, and how that would affect automatic control.
