🔍 Key Concepts

• Study the burner assembly details in illustration MO-0098 (number of nozzles, presence/absence of return lines, and type of ignition). • Recall how small auxiliary boilers typically control firing rate when steam demand changes (on–off vs. modulating control). • Think about what component in the choices would most likely be used to respond to boiler pressure changes rather than just to start ignition.

💭 Think About

• From the illustration, how many oil nozzles are actually shown, and does this match any choice that mentions multiple nozzles? • Do you see any indication of a fuel return line or control valve in the drawing, or only a single supply to the nozzle? • Which option describes a method that changes the amount of heat input with changing steam pressure, rather than just providing a spark for ignition?

✅ Before You Answer

• Verify whether the illustration shows a single nozzle or a triple nozzle assembly. • Check if there is any sign of an oil return line and control valve in the figure. • Separate out which choice describes combustion-rate/load control and which choices describe only ignition hardware or unrelated components.
