🔍 Key Concepts

• Boiler furnace flame characteristics when combustion is normal vs contaminated • How water in fuel oil affects burner performance and flame stability • Difference between problems caused by fuel pressure/temperature and those caused by contamination

💭 Think About

• What happens to a steady burner flame if small amounts of water are carried with the fuel into a hot furnace? Think about sounds, flame shape, and stability. • Which of the listed problems would most likely cause the flame to die down smoothly or go out, and which would cause noisy, spitting, or popping behavior? • How would low fuel temperature or low pressure change the flame appearance compared to contamination by another substance?

✅ Before You Answer

• Compare in your mind the symptoms of loss of fuel pump suction (pressure gauge behavior and flame change) vs a contamination issue. • Consider how low fuel oil temperature changes viscosity and spray pattern—does that usually cause sputtering/hissing or just poor atomization and smoky flame? • Remember that introducing water into a hot combustion space often leads to audible noises (pops, hisses) as it rapidly changes state.
