COMBUSTOR WITH A VARIABLE VOLUME PRIMARY ZONE COMBUSTION CHAMBER - A simplified explanation of the abstract

This abstract first appeared for US patent application 17805983 titled 'COMBUSTOR WITH A VARIABLE VOLUME PRIMARY ZONE COMBUSTION CHAMBER

Simplified Explanation

The patent application describes a combustor for a gas turbine that includes an outer liner and an inner liner, with a combustion chamber between them. The combustion chamber has a primary combustion zone at the upstream end. The combustor also includes an outer liner expanded primary volume portion and a secondary outer liner portion. One of these portions can be moved to adjust the volume of the primary combustion zone by opening and closing access to the outer liner expanded primary volume portion, thereby increasing or decreasing the volume of the primary combustion zone.

  • The patent application describes a combustor for a gas turbine with adjustable primary combustion zone volume.
  • The combustor includes an outer liner and an inner liner, with a combustion chamber between them.
  • The primary combustion zone is located at the upstream end of the combustion chamber.
  • The combustor also includes an outer liner expanded primary volume portion and a secondary outer liner portion.
  • The volume of the primary combustion zone can be adjusted by opening and closing access to the outer liner expanded primary volume portion.
  • This adjustment allows for increasing or decreasing the volume of the primary combustion zone.

Potential Applications

  • Gas turbine power generation systems
  • Aircraft engines
  • Industrial heating systems

Problems Solved

  • Inefficient combustion due to fixed primary combustion zone volume
  • Limited control over combustion process
  • Difficulty in optimizing combustion efficiency

Benefits

  • Improved combustion efficiency
  • Enhanced control over combustion process
  • Increased flexibility in optimizing combustion performance


Original Abstract Submitted

A combustor for a gas turbine has a combustor liner including an outer liner and an inner liner, a combustion chamber being defined between the outer liner and the inner liner. The combustion chamber includes a primary combustion zone at an upstream end of the combustion chamber. The combustor also includes an outer liner expanded primary volume portion, and a secondary outer liner portion. One of the outer liner expanded primary volume portion and the secondary outer liner portion is movable to adjust a volume of the primary combustion zone by opening and closing access to the outer liner expanded primary volume portion so as to increase and to decrease the volume of the primary combustion zone.
