🔍 Key Concepts

• mechanical atomizer types used in boiler burners (straight flow vs return flow) • how excess fuel is handled in a return flow atomizer at low firing rates • effect of oil pressure and atomization quality as load (firing rate) is reduced

💭 Think About

• Think about what happens to fuel pressure and spray quality when the boiler is operated at very low loads with a simple straight flow atomizer. • Which design feature of a return flow atomizer allows it to keep the fuel pressure (and therefore droplet size) relatively consistent over a wide firing range? • Look at each choice and ask: is this about maintaining proper atomization across the whole load range, or only about performance at either high or low end?

✅ Before You Answer

• Identify which option talks about pressure and atomization quality at low loads rather than only high-load performance. • Check which choices confuse combustion quality with atomization control; focus on atomizer pressure/droplet size, not general combustion claims. • Eliminate any option that describes a feature that would be equally true for a straight flow atomizer and not unique to return flow designs.
