🔍 Key Concepts

• Fuel oil atomizer components in marine burners • Difference between fuel-side parts (that shape the oil spray) and air/ignition parts (that assist combustion) • Role of an orifice plate in atomizing and metering fuel

💭 Think About

• Which choice is most directly involved with shaping or distributing the fuel oil spray itself, rather than supplying air or ignition? • In a typical pressure-jet or mechanical atomizer, what part works together with the orifice plate to form the correct spray pattern? • Which listed parts are usually associated with the burner register/combustion space rather than being inside the fuel nozzle/atomizer body?

✅ Before You Answer

• Eliminate any parts whose main job is igniting the fuel rather than atomizing it. • Eliminate parts whose main job is directing air flow into the furnace, not shaping the oil spray. • Focus on the choice that is normally found inside or immediately at the outlet of the atomizer nozzle along with the orifice plate.
