🔍 Key Concepts

• Fuel combustion quality and what complete vs incomplete combustion looks like in a boiler • How atomization (breaking fuel into fine droplets) affects smoke color and combustion • Relationship between firing rate / fuel pressure and visible stack emissions (color and density)

💭 Think About

• Think about what you would expect to see at the stack when combustion is clean and efficient versus when it is poor. • Which condition would most likely produce a light brown haze rather than dark smoke, no visible smoke, or a sharp change in stack appearance? • How does a problem with fuel atomizers usually show up visually at the stack compared to simply increasing firing rate with otherwise good burners?

✅ Before You Answer

• Match the color and description (light brown haze) with typical combustion indicators you’ve studied (e.g., black, gray, white, or no visible smoke). • Consider whether good fuel combustion usually produces a visible haze or tends to minimize visible stack emissions. • Ask whether increased fuel pressure or high firing rate alone, with otherwise proper combustion, normally changes the smoke to this color.
