🔍 Key Concepts

• Viscosity and temperature relationship for fuel oils • How fuel heating systems affect burner performance • Difference between pressure/flow changes and actual viscosity changes

💭 Think About

• Which option directly changes the fuel’s resistance to flow (its thickness) before it reaches the atomizer? • Do pressure and orifice size change the fuel’s actual viscosity, or only how it is delivered/sprayed? • Which choice involves adding or removing heat from the fuel itself?

✅ Before You Answer

• Identify which option clearly adds heat to the fuel before atomization • Eliminate options that only alter mechanical delivery (pressure or nozzle size) without changing fuel properties • Consider whether mixing heavier fuel with existing fuel would increase or decrease viscosity overall
