Question 1 of 27070

Water emulsified in the fuel oil when supplied to a boiler is indicated by __________.

🔍 Key Concepts

• Boiler combustion characteristics when fuel quality changes • Effects of water contamination in fuel oil on flame appearance and sound • How fuel pressure is normally affected** by water vs. mechanical problems**

💭 Think About

• Think about what happens to a steady burner flame when water droplets suddenly reach the burner tips. • Which of the listed symptoms are related to combustion in the furnace, and which are more related to pumping or supply problems? • If water is mixed in the fuel, would it consistently change pressure, flame behavior, exhaust appearance, or more than one of these?

✅ Before You Answer

• Identify which option(s) are directly caused by water flashing to steam at the burner. • Consider whether fuel oil pressure would necessarily drop just because water is present in the oil. • Decide if each symptom could occur independently for other reasons (e.g., mechanical fault, air setting), not just water in the fuel.
