🔍 Key Concepts

• burner atomization steam in marine boilers • difference between fuel pressure/temperature control and fuel atomization • how fine fuel oil droplets and swirl affect combustion efficiency

💭 Think About

• Ask yourself: what does atomization actually do to the fuel oil as it leaves the burner? Does it mainly change its pressure, its temperature, or its spray pattern? • Which choice describes an effect that directly improves mixing of fuel and air in the furnace, rather than something that happens elsewhere in the fuel system? • Look at each option and decide: is this something normally done by pumps/heaters, or is it something that happens right at the burner tip?

✅ Before You Answer

• Eliminate any options that sound like the job of fuel pumps (pressure control). • Eliminate any options that sound like the job of fuel oil heaters (temperature control). • Focus on the option that directly relates to the shape and movement of the fuel spray as it leaves the burner.
