🔍 Key Concepts

• Fuel oil atomization at the burner tips and why droplet size matters for combustion • Effect of fuel temperature and viscosity on burner performance • Risks of introducing air or contaminants into a boiler fuel system during light-off

💭 Think About

• Think about what condition the fuel must be in so it will burn cleanly and evenly as it leaves the burner nozzles. • Consider how temperature affects fuel thickness (viscosity) and how that changes the spray pattern at the burners. • Ask yourself: which choices would actually create a safer, more reliable flame for the initial light-off of a cold boiler?

✅ Before You Answer

• Verify which option directly supports proper combustion and clean flame formation at the burners. • Eliminate any option that would increase the risk of flame failure or explosion (such as air in the fuel). • Focus on the answer that relates to fuel properties at the burner, not general cleanliness or pump performance.
