🔍 Key Concepts

• Automatically fired auxiliary boiler operation and purpose of variable capacity burners • How pressure atomizing burners control fuel delivery and combustion rate • Difference between simple on/off control and modulating (continuous) control of burner capacity

💭 Think About

• First, think about what it means for a burner to have variable capacity rather than just being on or off. Which control method allows smooth changes in firing rate? • Consider how a pressure atomizing system actually changes the amount of fuel burned: does it do this by changing something in the fuel circuit, the air circuit, or purely by start/stop? • Look at each option and ask: would this method allow fine control to maintain nearly constant steam pressure, or would it cause larger pressure swings?

✅ Before You Answer

• Identify which choices describe true modulation of burner output versus simple cycling control • Recall that in a pressure atomizing system, atomization quality and fuel flow are closely related to fuel pressure at the burner or returning from it • Verify which variable (fuel pressure, air pressure, or speed of a mechanical element) is actually adjusted in a variable capacity pressure atomizing burner on marine auxiliary boilers
