Q

After a boiler generating tube has been plugged, __________.

🔍 Key Concepts

• Boiler generating tubes function and what happens when one is taken out of service (plugged) • Effect of plugging a tube on circulation, pressure, and temperature in the boiler • Normal safety practices after isolating a defective pressure part

💭 Think About

• If a tube is plugged, is it still carrying steam/water, or is it effectively sealed off from flow? How would that affect the need to change firing or steam flow rate? • Would making a hole in a defective, plugged tube increase safety or create another possible leak path? Think about pressure containment. • Consider whether all three listed actions are standard practice, or whether one or more would be unnecessary or unsafe.

✅ Before You Answer

• Verify what plugging a tube is intended to accomplish (remove it from pressure service vs. keep it in limited service). • Check whether standard boiler procedures call for adjusting firing rate automatically after plugging a single tube, or only when capacity is significantly reduced. • Consider whether creating an additional opening in a defective pressure part is consistent with normal marine boiler safety practice.
