The presence of moisture contamination within fuel oil leads to____________________?
Show answer Hide answer
Answer: C. cause sputtering, possibly extinguish¬ing flame
Explanation
Moisture contamination in fuel oil forms microscopic water droplets within the liquid fuel. As these droplets pass through the burner nozzle, they rapidly vaporize into steam. This sudden expansion causes sputtering and can severely destabilize or extinguish the flame. Fuel oil storage tanks can accumulate water due to atmospheric condensation and temperature changes. Emulsified water disrupts the steady atomization process required for efficient burner operation. Proper preheating and fuel filtration systems are used to remove moisture before combustion.
Boiler operators must regularly drain tank sumps to prevent moisture-induced burner flameouts. Flame instability in industrial furnaces leads to unburned fuel emissions and safety hazards. Maintaining clean and dry fuel oil ensures reliable combustion efficiency in heating systems. Keeping burner tips cool is an undesirable effect that wastes thermal energy and lowers efficiency. Aiding in proper combustion requires dry fuel, whereas moisture disrupts stable flame propagation. Cleaning nozzles is incorrect because water contamination causes fouling and operational disruptions.
