Q

Poor atomization accompanied by an elongated flame from a steam atomization burner is MOST likely caused by __________.

🔍 Key Concepts

• steam atomization and how steam pressure/condition affects fuel spray quality • relationship between fuel oil temperature, viscosity, and atomization • which fuel property (Cetane vs Octane) is associated with diesel vs gasoline fuels

💭 Think About

• Think about what happens to fuel droplets if the fuel is too cold and viscous when it reaches the burner nozzle. • Consider which choice directly changes the size and shape of the fuel spray coming out of the burner tips. • Ask yourself: which options mainly affect combustion timing or air supply, and which option affects how finely the fuel is broken up into droplets?

✅ Before You Answer

• Identify which option directly affects fuel viscosity at the burner nozzle. • Verify which fuel property (Cetane number) applies to diesel-type fuels and what it mainly influences (ignition quality vs spray pattern). • Check which of the listed issues would most likely show up as poor atomization with a long, lazy flame rather than a purely air/draft issue.
