Study Notes

Combustion Section

  • Typically located between the compressor and turbine sections in a gas turbine engine

Combustion Chamber

  • Primary function: to mix fuel and air, ignite, and sustain combustion

Fuel Injection System

  • Located in the combustion chamber to inject fuel into the combustion zone

Ignition Source

  • Typical ignition source for gas turbines: high energy capacitor discharge system

Fuel Drainage System

  • Accomplishes the important task of draining excess fuel from the combustion chamber

High Energy Capacitor Discharge System

  • Primary function: to provide the high voltage necessary to create a spark for ignition in a gas turbine engine

Fuel Nozzles

  • Typically located in the combustion chamber to atomize and distribute fuel

Combustor Elements

  • Basic elements of a typical combustor in a gas turbine engine: combustion chamber, fuel nozzles, and igniter
