Abstract
A combustion chamber (5) for a gas turbine is adapted for flameless oxidation of fuels. This circulation flow has an internal space (9) in which a large-volume circulation flow is established. To this end, the combustion chamber supplies a hot exhaust stream to the introduced air, the mass flow rate of which exceeds the fresh air stream. The fresh air and the fuel are fed to the combustion chamber in the same direction, roughly parallel to the wall.
Claims20
A gas turbine comprising:
- a compressor;
- a turbine;
- a combustion chamber having a wall that encloses and defines an internal reaction space having a longitudinal axis, said combustion chamber having inlets for directing air and/or fuel into said internal space in substantially parallel relation to said longitudinal axis, said combustion chamber having an outlet coaxially located on said longitudinal axis and connected to said turbine for discharging exhaust gases to said turbine,
- said internal space being configured such that a relatively large circulating gas flow stream can be formed in the internal space so as to maintain a flameless oxidation process, and
- said inlets each being disposed a distance from said longitudinal axis greater than the radius of said discharge orifice.
