Question 1 of 27070

When a soot fire occurs, damage to an economizer can be minimized if you __________.

🔍 Key Concepts

• Economizer function in a boiler system and where it is located in the gas path • How soot fires behave and why metal overheating is dangerous • Effect of maintaining vs. stopping water flow through heated surfaces during a fire

💭 Think About

• Think about what happens to the economizer metal temperature if hot gases and a soot fire are present but no water is flowing inside the tubes. • Which choice helps carry heat away from the economizer tubes so they are less likely to warp, crack, or rupture? • Which options might actually spread the fire or remove critical cooling from the tubes?

✅ Before You Answer

• Identify which option keeps cooling on the economizer tubes during the fire. • Check which actions could increase air supply and make the soot fire worse. • Consider whether suddenly isolating or draining the economizer could cause tube overheating or pressure problems.

increase the forced draft fan speed to blow out the fire

maintain feed water flow through the economizer while extinguishing the fire

secure the economizer and open the drain valve to prevent steam pressure buildup
