Gas turbine engine system and method of providing a fuel supplied to one or more combustors in a gas turbine engine system

A method for providing a fuel supplied to one or more combustors in a gas turbine engine system, comprising:

• partially oxidizing a fraction of primary fuel in one or more fuel circuits of the gas turbine engine system, in the absence of a catalyst, with a non-catalytic fuel reformer to form a reformate, wherein the fraction of primary fuel and an oxidant are mixed and burned in a predetermined ratio in the non-catalytic fuel reformer;
• causing a water-gas shift reaction in a non-catalytic reaction passage in the non-catalytic fuel reformer by directing a selected amount of secondary fuel and a selected amount of steam into the partially oxidized fraction of fuel, thereby producing a reformate;
• and
• mixing the reformate with a remaining fraction of fuel to produce a mixed fuel stream and supplying the mixed fuel stream to the one or more combustors.

A gas turbine engine system, comprising:

• a compressor, a combustor, and a turbine;
• a fuel system comprising one or more fuel circuits configured to provide fuel from a fuel flow to the combustor;
• a non-catalytic fuel reformer in fluid communication with the one or more fuel circuits, wherein the non-catalytic fuel reformer is configured to receive an oxidant from an oxidant flow and a fraction of primary fuel in the one or more fuel circuits in a predetermined ratio and to produce a partially oxidized fuel;
• a secondary fuel supply to add a secondary fuel flow to the partially oxidized fuel from the non-catalytic fuel reformer;
• a water supply to add a steam flow to the partially oxidized fuel from the non-catalytic fuel reformer;
• and
• a non-catalytic reaction passage in a downstream portion of the non-catalytic reformer, the non-catalytic reaction passage configured to receive a combination of the secondary fuel flow, the steam flow and the partially oxidized fuel.
