Combustion Liners

Combustion Liners

  • Part of gas turbines.
  • Helps control the combustion of fuel and hair mixture.
  • Withstand high temperatures and pressures.
  • Promotes efficient and stable combustion.
  • Helps reduce emissions.


A combustion liner is a crucial component of gas turbines. It is typically made of high-temperature resistant materials such as ceramics or metal alloys such as Nickel-based superalloys. They are supposed to bear the intense heat of around 4000F. So, these materials are chosen for their ability to withstand the extreme combustion conditions within gas turbines. These combustion liners prevent the direct contact of hot combustion gases with the combustor and turbine shaft. Considering the heat intensity, it protects them from damage.

Additionally, it has an essential function in gas turbines. It provides a controlled environment for the combustion of fuel and air mixture. Evenly distributing the fuel mixture and promoting complete combustion ensures efficient and stable combustion. The unique intricate patterns of holes and slots on it allow the cooling air to flow through it. This cooling air creates a protective film along the inner surface of the liner, which absorbs heat and prevents excess thermal stress.

Moreover, a combustion liner helps reduce emissions by allowing the combustion process to occur in a controlled manner. A controlled environment prevents any fuel-rich or fuel-lean regions from being contaminated. Otherwise, it could lead to incomplete combustion and the formation of harmful emissions. Promoting uniform combustion helps maximize the energy output and minimize the environmental impact of gas turbines. Conclusively, it performs the role of heat shields of gas turbines to ensure smooth operations. Increase the power output today with the best quality liners for your gas turbines!
