Q

Improper fuel oil burner atomization can be generally attributed to __________.

🔍 Key Concepts

• Atomization of fuel oil and why droplet size matters for combustion • The relationship between fuel temperature, viscosity, and spray quality through a burner nozzle • How draft (air pressure) affects combustion differently from how fuel properties affect atomization

💭 Think About

• Ask yourself: which option directly affects the fuel’s ability to break into a fine spray as it passes through the burner tip? • Consider which choices mainly affect air supply or combustion rate rather than the actual quality of the fuel spray leaving the nozzle. • Think about how changing fuel temperature changes viscosity, and how that would change how easily the fuel passes through the atomizing orifice.

✅ Before You Answer

• Identify which choices deal with fuel properties at the nozzle versus air/combustion conditions in the furnace. • Check your understanding of how viscosity changes with temperature and how that affects the fineness of the spray. • Confirm which factor would most likely cause fuel to come out in larger droplets or a poor spray pattern, leading to improper atomization.
