🔍 Key Concepts

• automatic (pressure-fired) auxiliary boiler operations and what normally causes the furnace and casing to shake • difference between steady combustion and irregular, pulsing ignition in a boiler • symptoms of fuel supply problems versus combustion instability

💭 Think About

• Which of these choices would most likely create a rhythmic or hammering effect in the furnace, rather than just a loss of flame or pressure? • If the boiler is still lighting off repeatedly, what condition could cause small explosions or surges each time fuel ignites? • Consider what happens when the fuel/air ratio or ignition timing is off in an automatically fired boiler—how would that feel and sound to someone standing nearby?

✅ Before You Answer

• Identify which option describes an ongoing combustion irregularity rather than a one-time failure event. • Ask: does this condition make the boiler stop firing, or does it make it fire in an unstable, surging way? • Match the symptom: excessive vibration with pressure surges / mini-explosions in the furnace, not just loss of flame or pump output.
