The combustion chamber is located between the compressor and turbine sections of a gas turbine engine. It mixes fuel and air efficiently and controls the burning of fuel. It also dampens hot combustion gases and ensures air is expanded and accelerated through the turbine with minimal pressure loss and maximum heat release. The combustion chamber plays a crucial role in determining many of an engine's operating characteristics including fuel efficiency, emission levels, and response to changing conditions.

- 2. Also known as the combustor, burner, flame holder Intro Process Fuel Supply Types COMBUSTIONMaterials CHAMBER AE 424
- 3. l ocation typically located directly between the compressor diffuser and turbine section Intro Process Fuel Supply Types COMBUSTIONMaterials CHAMBER AE 424
- 8. A ir Flow Types Intro Primary Cooling Intermediate Dilution Process Fuel Supply Types COMBUSTIONMaterials CHAMBER AE 424
- 11. Primary Air= approximately 25% of total air Remaining 75%= used to form an air blanket around the burning gases and to lower the temperature Intro Process Fuel Supply Types COMBUSTIONMaterials CHAMBER AE 424
- 12. The air used for burning fuel is “primary” air. • Cooling Air drops the temperature to a value that the turbine inlet guide vanes can withstand • Cooling air is “secondary” air (controlled and directed by holes and louvers) Supply Intro Process Fuel Types COMBUSTIONMaterials CHAMBER AE 424
- 13. • Continuous airflow helps prevent CARBON from forming on the inside of the liner • Carbon deposits can cause HOT SPOTS, block cooling air passages, which then shortens burner life Intro Process Fuel Supply Types COMBUSTIONMaterials CHAMBER AE 424
- 15. • Blends air and fuel proficiently • Controls the burning of large amounts of fuel and air efficiently • Dampens the hot combustion gases • Ensures that the air is expanded and accelerated ** must be accomplished with minimum Intro pressure loss and Fuel Supply Process maximum heat Types release COMBUSTIONMaterials CHAMBER AE 424
- 16. Combustors play a crucial role in determining many of an engines operating characteristics, such as •fuel efficiency, •levels of emissions and •transient response (the response to changing conditions such a fuel flow and air speed) Intro Process Fuel Supply Types COMBUSTIONMaterials CHAMBER AE 424
