Q
The rotary-cup burner atomizes the fuel oil by which of the following methods?
A
Through the use of 135 psig auxiliary steam.
B
The oil is atomized as it is forced out of the small exit hole of the burner tip.
C
Through the use of two oil passages in the atomizer barrel.
D
By throwing the fuel oil off the edge of a rotating tapered cup.

🔍 Key Concepts

• How a rotary-cup burner physically handles fuel oil before ignition • The difference between pressure atomization and mechanical/centrifugal atomization • Visualizing what happens to liquid on the edge of a rapidly spinning cup or disc

💭 Think About

• Picture fuel oil entering a spinning cup: what forces act on the liquid as the cup rotates? • Which options describe pressure through an orifice versus spinning and throwing the oil into small droplets? • Which method relies mainly on high-pressure fluid (steam or oil) and which relies mainly on mechanical rotation?

✅ Before You Answer

• Identify which choices describe pressure-jet/steam atomization rather than a rotary-cup design • Focus on the choice that mentions rotational motion or a rotating part acting on the fuel • Eliminate any options that could apply to a simple pressure nozzle burner without any rotating cup or disc
