🔍 Key Concepts

• Boiler furnace purging and why it is done before lighting off • Dangers of unburned fuel vapors in an enclosed furnace or combustion chamber • Normal sequence of operations when starting a cold boiler

💭 Think About

• Ask yourself what the greatest immediate safety concern is before putting a flame in a cold, closed space that may have had fuel or vapors present. • Consider which option directly removes any potentially explosive mixture from the furnace or gas passages, rather than just adjusting water or steam side valves. • Think about standard light‑off procedures: which step must be completed to prevent a furnace explosion when ignition occurs?

✅ Before You Answer

• Verify which action would clear the furnace or gas path of combustible vapors or residual fuel before introducing a flame. • Check which choices deal with water/steam side operations (mud drum, surface blow, superheater vent) rather than combustion space safety. • Confirm which step appears in standard boiler start‑up/light‑off checklists specifically as an explosion‑prevention measure.
