🔍 Key Concepts

• Complete combustion vs. incomplete combustion in oil-fired or fuel-fired boilers • Visual indicators of combustion quality seen in the stack/exhaust • Relationship between visible smoke/haze and unburned fuel/soot (wasted energy)

💭 Think About

• Which stack condition suggests that the least amount of unburned fuel, soot, or particulate matter is being carried out with the exhaust? • How does visible color or density of smoke relate to fuel that did NOT release its full heat value in the furnace? • If boiler efficiency is highest, where is almost all of the fuel’s energy going: out the stack, or into the water/steam system?

✅ Before You Answer

• Identify which option suggests minimum visible smoke or particles (least unburned fuel). • Eliminate any option that clearly indicates unburned carbon/soot or poor atomization. • Think about which stack appearance most chief engineers aim for when tuning burners for best efficiency and cleanest burn.
