MS6001 Combustion Liner

The MS6001 Combustion Liner is a critical hot-section component in the GE MS6001 series, used in industrial power generation. It forms the internal wall of the combustion chamber, where compressed air mixes with fuel to produce high-temperature gases that drive the turbine rotor. Precision engineering and material performance are vital, as this component must withstand extreme thermal, mechanical, and chemical stresses over prolonged operation.

Advanced manufacturers like HGTP specialize in producing MS6001 combustion liners using high-temperature alloys, precision CNC machining, and strict quality assurance, ensuring reliable operation in demanding industrial environments.

Function of the MS6001 Combustion Liner

The combustion liner performs several essential roles in the gas turbine:

Flame Containment

It contains the combustion flame, preventing heat damage to surrounding engine components.

Fuel-Air Mixing

The internal geometry ensures optimal mixing of fuel and compressed air for efficient combustion.

Thermal Protection

Cooling holes and film cooling channels protect the liner surface from extreme temperatures, maintaining structural integrity.

Structural Support

Provides mounting surfaces for fuel nozzles and combustion chamber internals.

Materials Used

The liner must endure temperatures up to 1100°C and thermal cycling. Materials include:

Nickel-Based Superalloys

• Inconel 625

• Inconel 718

• Hastelloy X

Features: high-temperature strength, oxidation and corrosion resistance, excellent thermal fatigue resistance.

Heat-Resistant Stainless Steel

• AISI 321, AISI 347
  Used for less stressed areas; provides dimensional stability and weldability.

Manufacturing Process

Producing the MS6001 combustion liner requires advanced turbine manufacturing technology:

Sheet Forming and Segment Fabrication

• Rolling, hydroforming, or deep drawing forms the cylindrical or segmented liner geometry.

Welding and Assembly

• TIG, laser, or electron beam welding assembles segments with minimal distortion.

CNC Machining

• Machining critical surfaces, mounting flanges, and alignment features to ±0.02 – ±0.05 mm tolerances.

Cooling Hole Drilling

• Hundreds of precision holes (0.5 – 2 mm diameter) allow cooling airflow along the liner surface.

• Methods: laser drilling, EDM, or precision mechanical drilling.
