🔍 Key Concepts

• complete combustion of fuel in a boiler • visual indicators of too much air vs too little air in stack gases • relationship between smoke color and combustion efficiency

💭 Think About

• What does the presence of visible smoke (white, brown, or black) usually suggest about how completely the fuel is burning? • If you add excessive combustion air to make smoke disappear, what effect does that have on boiler efficiency? • Which stack condition indicates good combustion without wasting heat up the stack?

✅ Before You Answer

• Compare what no visible smoke vs a light haze vs white smoke typically means on a fired boiler • Consider whether maximum fuel temperature always improves efficiency, or if there is an optimal range instead • Think about which option best matches standard industry practice for properly adjusted burners on marine boilers
