Combustion Chamber 5/5

  1. 1. Materials • combustion chamber liner= welded high-nickel steel HOTTEST ZONE- first upstream third of its length (flame zone). The MOST SEVERE operating periods: during engine idle (reduced air) and maximum rpm (power) operation Intro Process Fuel supply Types COMBUSTIONMaterials CHAMBER AE 424
  2. 2. Combustion Chamber is part of the Hot Section with Exhaust and Turbines FAQ: Hot spots on tail cone indicate that the combustion chamber of a jet engine is not properly working
  3. 3. Major Design Consideration Problem: How to have a continuous ignition flame burning despite the fast flowing air around it? Solution: Create a purposeful turbulence around the flame. Intro Process Fuel supply Types COMBUSTIONMaterials CHAMBER AE 424
  4. 4. Certain materials may be used to mark combustion and turbine components during disassembly and assembly  layout dye, chalk, and some commercial felt-tip markers are considered ACCEPTABLE for use in marking parts that are directly exposed to an engine's gas path such as turbine blades and disks, turbine vanes, and combustion chamber Intro Process Fuel supply Types liners COMBUSTIONMaterials CHAMBER AE 424
  5. 5. • In which type of turbine engine combustion chamber is the case and liner removed and installed as one unit during routine maintenance? CAN • The air passing through the combustion chamber of a turbine engine is used to support combustion and to cool the engine. Intro Process Fuel supply Types COMBUSTIONMaterials CHAMBER AE 424
  6. 6. • In which type of turbine engine combustion chamber is the case and liner removed and installed as one unit during routine maintenance? CAN • The air passing through the combustion chamber of a turbine engine is used to support combustion and to cool the engine. Intro Process Fuel supply Types COMBUSTIONMaterials CHAMBER AE 424
