🔍 Key Concepts

• Relationship between air supply and combustion quality in boilers • Typical causes of black smoke (incomplete combustion) from marine boilers • How soot deposits and fuel oil temperature affect combustion and smoke color

💭 Think About

• First, think about what black smoke indicates about how completely the fuel is burning. Is the furnace getting too much fuel, too little air, or poor fuel atomization? • If increasing air box pressure does NOT reduce the black smoke, which options can you rule out that are directly related to air supply or air heating? • Consider which listed condition most commonly leads to poor atomization or incomplete combustion even when plenty of air is available.

✅ Before You Answer

• Identify which options are primarily air-side problems versus fuel-side or heat-transfer problems. • Ask: in which choice would extra air pressure at the boiler front not fix the underlying issue? • Recall that black smoke = unburned carbon/soot; which condition in the answers is most directly associated with increased soot formation in the furnace or on the gas side?
