Q

A two-element feed water regulator not only responds to changes in water level, but is also designed to react to __________.

🔍 Key Concepts

• Boiler feed water regulators and how many "elements" (signals) they use • The relationship between steam generation rate and boiler water level • Why adding a second control signal makes level control more stable during load changes

💭 Think About

• When boiler load suddenly increases, which variable changes first and can be sensed quickly, before the actual drum water level drops? • Which of the answer choices is directly tied to how fast steam is leaving the boiler? • In a two-element system, one element is drum level. Which other measurement, when combined with level, helps anticipate level changes instead of waiting for them?

✅ Before You Answer

• Identify which choice is directly linked to boiler load (how hard the boiler is working) • Eliminate choices that are secondary effects rather than primary indicators of steam demand • Confirm that the chosen variable would help the controller anticipate level change, not just react after it happens
