Which of the following types of feedwater regulators is commonly used with a water-tube, natural circulation, auxiliary boiler?

🔍 Key Concepts

• Natural circulation boilers and how they move water/steam without pumps • How feedwater regulators control water level in auxiliary (small) boilers • Difference between on/off type controls and modulating controls for smooth level control

💭 Think About

• Think about what kind of water level control a water-tube, natural circulation auxiliary boiler needs: sudden on/off changes or smooth, continuous regulation? • Look at each option and ask: is this typically used for precise water level control in boilers, or is it more for temperature/pressure on-off control? • Which of these devices is designed to adjust the feedwater flow in proportion to the actual water level, rather than just switching at high/low points?

✅ Before You Answer

• Identify which option is known as a continuous (modulating) level controller rather than a simple thermostat or switch • Eliminate any options that primarily sense temperature instead of water level or steam pressure • Consider what control type is preferred in water-tube auxiliary boilers to avoid rapid level swings and potential tube damage
