🔍 Key Concepts

• Boiler furnace explosions and how unburned fuel can ignite • Purpose of purging a boiler furnace after flame failure • Manufacturer and safety procedures following an accidental flameout

💭 Think About

• What happens to any unburned fuel or vapor left in the furnace when the flame goes out unexpectedly? • Before introducing a new flame, what must be done to remove any potentially explosive mixture from the furnace? • Which choice clearly addresses removing dangerous fuel/air mixtures rather than just cooling or moving fuel around?

✅ Before You Answer

• Verify which option specifically ensures the removal of unburned fuel and vapors from the furnace space. • Check which procedure is normally required by standard boiler operating and safety manuals after a flameout. • Confirm that the step you choose would prevent a furnace explosion if ignition is attempted afterward.
