Question 1 of 27070

If a large number of tubes has failed, you can minimize damage to a boiler by __________.

🔍 Key Concepts

• Boiler casualty procedures when tubes fail or rupture • Effects of continuing to heat a damaged boiler vs. cooling it down in a controlled way • Relationship between firing rate, steam pressure, and feedwater supply in an emergency

💭 Think About

• What is the safest way to quickly reduce heat input and pressure inside a boiler with multiple tube failures? • Would you want to keep the boiler in service (on the line) or isolate it from the steam system when it has many damaged tubes? Why? • How would increasing air flow or feed water affect pressure, water level, and the spread of damage in a boiler that is already leaking badly?

✅ Before You Answer

• Identify which choices remove heat input to the boiler and which ones increase it • Check which option safely reduces boiler pressure and isolates it from the steam system • Avoid any option that would intensify combustion or stress on already failed tubes

Question 1 of 27070

If a large number of tubes has failed, you can minimize damage to a boiler by __________.

securing the fires, steam stops, and relieving boiler pressure

securing the fires, feed stops, and leaving the boiler cut on the line

increasing the feed water supply to keep the boiler cool

speeding up the forced draft fans to blow steam up the stack
