The invention discloses a gas turbine engine system and a method of providing a fuel supplied to combustors. According to one aspect of the invention, a method for providing a fuel supplied to one or more combustors in a gas turbine engine system includes 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. The method also includes 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 combus
