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.
