Q

Which of the following statements about a coil-type forced circulation auxiliary water-tube boiler is correct?

🔍 Key Concepts

• Coil-type forced circulation water-tube boiler characteristics (small water content, high heating surface) • The path of water vs. steam in this type of boiler (what actually circulates in the coils) • How these boilers handle changes in steam demand compared with large drum-type boilers

💭 Think About

• Think about where steam actually forms in this system: is it inside the coils, in a drum/flash chamber, or somewhere else? • Consider what is being pumped around the system by the circulation pump: is it water, steam, or a mixture? • Ask yourself what a small water inventory and high heat input would do to the speed of pressure/steam output changes when demand goes up or down.

✅ Before You Answer

• Verify which component in a coil-type boiler acts as the steam separating space (often called a flash or steam chamber). • Confirm whether water or steam is recirculated through the coils in a forced-circulation design. • Check what normally happens to unevaporated feedwater in a closed boiler system: does it go to the bilge or stay in the system?
