Question 1 of 27070

The amount of oil atomized by a straight mechanical fuel oil burner depends on the sprayer plate size and the __________.

🔍 Key Concepts

• mechanical fuel oil burners and how they atomize fuel • the role of sprayer plate (nozzle) size in controlling fuel flow • which pressure acts directly on the fuel at the burner tip

💭 Think About

• Ask yourself: Which of these pressures is applied directly to the oil just before it passes through the sprayer plate openings? • Which pressures mainly affect the air/furnace environment rather than the liquid fuel itself? • In a straight mechanical burner, what force actually breaks the oil into fine droplets at the nozzle?

✅ Before You Answer

• Identify which answer choices relate to air-side pressures vs. fuel-side pressure. • Confirm that the factor you choose works together with sprayer plate size to determine the amount of oil sprayed. • Eliminate any pressures that primarily influence combustion air rather than the fuel being atomized.
