Abstract
An adiabatic combustor for a gas turbine including: (a) a combustion chamber designed and configured to produce high-pressure combustion gases for the turbine, the combustion chamber having a primary combustion zone containing a substantially vitiated-air zone; (b) at least one primary air inlet providing air to the primary combustion zone, and (c) a fuel injector for injecting fuel, disposed such that the fuel is directly introduced to the vitiated-air zone, wherein the primary air inlet is positioned and directed, and the combustion chamber is designed and configured, so as to produce an internal recirculation that generates a toroidal vortex within the primary combustion zone, thereby producing therein the vitiated-air zone and maintaining therein a state of flameless oxidation.

A system comprising:
- an adiabatic combustor for a gas turbine, said combustor including:
- a) a combustion chamber designed and configured to produce high-pressure combustion gases for said turbine, said combustion chamber having a primary combustion zone containing a substantially vitiated-air zone;
- b) at least one primary air inlet providing air to said primary combustion zone, and
- c) a fuel injector for injecting fuel, disposed such that said fuel is directly introduced to said vitiated-air zone,
- said primary air inlet being positioned and directed, and said combustion chamber being designed and configured, so as to produce an internal recirculation that generates a toroidal vortex within said primary combustion zone, thereby producing therein said vitiated-air zone and maintaining therein a state of flameless oxidation.
A system comprising:
- an adiabatic combustor for a gas turbine, said combustor including:
- a) a high-pressure combustion chamber designed and configured to produce high-pressure combustion gases for said turbine, said combustion chamber having a primary combustion zone containing a substantially vitiated-air zone,
- b) a primary air inlet providing all primary air to said primary combustion zone;
- said primary air inlet being disposed in a first side of said combustion chamber, and
- c) a fuel injector for injecting fuel, said fuel injector being disposed in a second side of said combustion chamber, said second side being opposite to said first side,
- said primary air inlet being positioned and directed, and said combustion chamber being designed and configured, so as to produce an internal recirculation that generates a toroidal vortex within said primary combustion zone, thereby producing therein said vitiated-air zone and maintaining therein a state of flameless oxidation.
