Which section controls the mixing of fuel and air and contains the igniters?

• A. Intake Section
• B. Combustion Section
• C. Exhaust Section
• D. Accessory Section

Answer: (B)

The section where fuel and air come together and ignition happens is the combustion section. Inside the combustor, the air provided from the intake mixes with the metered fuel, and the igniters spark or heat to ignite that mixture. This is the heart of producing the high-energy gases used to drive the turbines. The intake section simply brings air in, the exhaust section handles the spent gases, and the accessory section houses pumps and other hardware—none of these mix fuel with air or ignite it.
