🔍 Key Concepts

• Return-flow variable capacity atomizer construction and purpose • How oil flow is split between nozzle flow and return flow in an automatic boiler burner • What internal part directly changes fuel throughput when firing rate changes

💭 Think About

• In a return-flow type atomizer, what happens to the excess oil that is not sprayed into the furnace? What controls this split between sprayed oil and returned oil? • Which listed option actually varies the capacity of the burner (how much oil is burned), rather than just influencing how well it burns (combustion quality)? • Inside an automatically fired boiler’s burner system, where is the "brains" of fuel metering usually located: in the pump, the air supply, or a special control element at the fuel valve/atomizer?

✅ Before You Answer

• Identify which choice refers to a metering/proportioning mechanism rather than a supply or operating condition (pressure, pump output, or air amount). • Ask: which component would the automatic control system move to increase or decrease firing rate? That’s the one that actually regulates the amount atomized. • Confirm that oil pressure or pump capacity alone do not automatically change burner firing rate unless passed through a controlling device that meters flow to the nozzle versus the return line.
