Q

The primary purpose of the heater used in a pressurized fuel oil system is to __________.

🔍 Key Concepts

• How fuel viscosity affects atomization in burners • Difference between viscosity, specific gravity, flash point, and fire point • What a heater can realistically change about fuel properties just before combustion

💭 Think About

• When fuel is sprayed through an atomizer or nozzle, which fuel property is most critical for forming a fine mist? • Can a small, in-line heater in a fuel system significantly change properties like flash point or fire point, or is it mainly used to adjust flow behavior? • Which option describes a change that happens quickly and reversibly as temperature changes, rather than a permanent change in the fuel’s chemistry?

✅ Before You Answer

• Be clear on the definition of viscosity (thickness / resistance to flow) versus specific gravity (density compared to water) • Recall what flash point and fire point mean and whether they are fixed characteristics of a fuel type • Ask: Which choice best matches what manufacturers and engineers are trying to achieve at the burner nozzle/atomizer?
