🔍 Key Concepts

• complete vs. incomplete combustion in a boiler furnace • the typical products when fuel burns with enough oxygen vs. not enough oxygen • how carbon in the fuel changes form depending on air (oxygen) availability

💭 Think About

• When fuel burns with plenty of air, which gas is the main product of the carbon in the fuel? • If the air supply is restricted, what happens to that carbon—does it become more oxidized or less oxidized? • Which of the choices is a sign that the carbon did NOT get fully burned (not fully oxidized)?

✅ Before You Answer

• Identify which gases in the choices contain carbon and which do not • Think about which gas is associated with soot, smoke, and poor combustion efficiency in boilers and engines • Confirm which product is typical of fuel-rich (oxygen-poor) combustion rather than clean, efficient combustion
