Abstract:
1. A method of operating a gas turbine system, the method comprising: receiving a mixture of air and fuel along a reaction chamber flow path in a reaction chamber of the gas turbine system; igniting the fuel to raise the temperature of the mixture to or above an auto-ignition temperature of the fuel; oxidizing the fuel while controlling a maximum temperature of the mixture in the reaction chamber to be between the auto-ignition temperature of the fuel and 1300° C., wherein a fuel oxidation catalyst material is not used during the oxidation; receiving a control flow comprising supplemental fuel through a plurality of ports located at a plurality of locations along the reaction chamber flow path in the reaction chamber, each of the plurality of ports being spaced from another of the plurality of ports along the flow path, each of the plurality of ports being connected to a supplemental fuel source for introduction of the supplemental fuel into the reaction chamber through the plurality of ports, and adjusting the control flow to control the maximum temperature of the mixture; and detecting a characteristic comprising a temperature at one or more positions in the reaction chamber; wherein adjusting the control flow comprises adjusting an amount of the control flow received into the reaction chamber based at least in part on the detected characteristic.
