Embodiment Construction

[0157] As described in detail below, disclosed embodiments of the present invention provide a gas turbine system incorporating a fuel reformer system. The systems and techniques described herein are used to enhance the power output and efficiency of gas turbine systems, such as staged gas turbine systems and reheat gas turbine systems. Reformer systems utilized in gas turbine systems are configured to provide mixing and reaction of a fuel slip stream with an oxygen slip stream to increase hydrogen concentration through premixed partial oxidation combustion. The introduction of hydrogen into the fuel allows for lowering of the lean flameout point and enables reduction of combustion dynamics to the gas turbine system. As used herein, the term "combustion dynamics" refers to fluctuations in oxygen pressure, temperature, heat release, and unsteady flow oscillations that affect the operation of engines, including gas turbines. Additionally, the term "lean flameout point" as used h...

Abstract

The invention relates to a premixed partial oxidation syngas generation and a gas turbine system. The gas turbine system includes a fuel reformer system comprising a fuel inlet configured to receive a fuel slipstream; an oxygen inlet configured to introduce an oxygen slipstream; a preconditioning zone configured to pretreat the fuel slipstream; a mixing zone comprising a premixing device configured to facilitate mixing of the fuel slipstream and the oxygen slipstream to form a gaseous premix; a reaction zone configured to generate a syngas from the gaseous premix; a quench zone configured to mix a fuel stream into the syngas to form a hydrogen-enriched fuel mixture; and a gas turbine configured to receive the fuel mixture.

Description

technical field [0001] The present invention relates generally to gas turbine combustion systems, and more particularly to fuel reformers based on premixed partial oxidation combustion for increasing the efficiency of gas turbine systems. Background technique [0002] There is a drive within the industry to produce new turbines that will operate efficiently without producing unwanted air polluting emissions. The major air polluting emissions typically produced by turbines burning conventional hydrocarbon fuels are nitrogen oxides, carbon monoxide, and unburned hydrocarbons. Oxidation of molecular nitrogen in a jet engine can be highly dependent on the maximum temperature in the reaction zone of the combustion system and the residence time the reactants achieve within the combustor at the maximum temperature. By maintaining the temperature of the reaction zone to form thermal NO X below the level of NO X There is not enough time for the formation reaction, thereby minimizi...
