🔍 Key Concepts

• Variable capacity, return flow-type fuel atomizer — how excess fuel is handled and recirculated • Difference between controlling how much fuel reaches the burner vs. how the fuel-air mix is shaped • What parameter in a return-flow system most directly changes the net fuel actually burned

💭 Think About

• In a return-flow atomizer, if total pump output stays the same, what must change so that less fuel is actually sprayed into the furnace? • Which choice deals with the amount of oil that is allowed to return instead of burning, rather than just air flow or spray pattern? • Think about which option you would adjust from the control system to match steam demand without constantly changing mechanical nozzle dimensions.

✅ Before You Answer

• Identify which choice directly affects net fuel flow to the furnace in a return-flow system • Separate options that mainly change air flow/combustion air pattern from those that change fuel circuit pressures/flows • Ask: in practice, which parameter can be smoothly modulated to track steam demand without stopping the burner?
