🔍 Key Concepts

• mechanical atomization of fuel oil in boiler burners • relationship between fuel pressure, fuel temperature, and droplet size • role of air supply and excess air in complete combustion

💭 Think About

• Which factors directly affect how finely the fuel is broken into droplets before burning? • Can proper combustion be achieved if you control only one of these factors (pressure, air, or temperature) while the others are wrong? • Think about what is needed simultaneously for clean, smokeless combustion with a stable flame in a marine boiler.

✅ Before You Answer

• Verify how fuel pressure influences the spray pattern and atomization quality. • Consider how fuel temperature changes viscosity and how that affects atomization in a mechanical (not steam) atomizer. • Check why the amount of air and excess air is critical to avoid smoke, soot, or unburned fuel in the furnace.
