What occurs in the burner section of a gas turbine engine?

• A. Fuel is burnt without air
• B. Air is cooled and returned to the engine
• C. Fuel is mixed with compressed air and ignited
• D. Air is extracted for auxiliary systems

Answer: (C)

In the burner section of a gas turbine engine, fuel is mixed with compressed air and ignited. This is a crucial part of the engine's operation because, after the air has been compressed in the compressor section, it is introduced into the burner where it mixes with fuel. The mixing and subsequent combustion of the fuel and air lead to the generation of high-temperature and high-pressure gases. These gases then expand through the turbine, providing the necessary energy for the engine to produce thrust. The process that occurs is vital to the overall efficiency and performance of the gas turbine engine, as it transforms the chemical energy stored in the fuel into thermal energy used to produce mechanical energy. The design of the burner ensures complete combustion and optimal energy release, contributing significantly to the engine's overall efficiency and power output.
