Q

In a multi-burner firebox, a burner tip with a worn and enlarged orifice will __________.

🔍 Key Concepts

• Burner tip orifice size vs. fuel flow rate in pressure-atomizing burners • Effect of improper atomization on flame shape and temperature distribution • Consequences of one burner in a multi-burner furnace behaving differently from the others

💭 Think About

• If an orifice becomes larger than designed, what happens to the amount of oil passing through at the same pressure, and how does that affect spray pattern? • In a multi-burner firebox, what would happen to overall furnace temperature distribution if one burner is putting out a different flame than the others? • Which options describe system-wide pressure effects, and which describe local combustion/flame effects at just one burner tip?

✅ Before You Answer

• Compare what a worn/enlarged orifice does to fuel flow rate and spray pattern at constant pressure • Think about how one abnormal burner would influence furnace temperature uniformity rather than the return line or other system components • Eliminate choices that imply no change in operation when a key component is out of design tolerance
