Abstract: A method of reducing a modified Wobbe index of a fuel stream fed to diffusion combustors of a gas turbine that is used in connection with an IGCC installation in which a nitrogen stream is fed into the head ends of the combustor of NOx control and the modified Wobbe index of the fuel stream has been increased in an amount that is greater than at least about 10 percent of a design Wobbe index for the fuel to be fed to the gas turbine. The reason for the increase is the conversion of the carbon monoxide within the fuel stream to hydrogen and carbon dioxide by a water gas shift reaction and subsequent removal of the carbon dioxide. The nitrogen stream is maintained at the same level both with and without conversion and subsequent removal of carbon atoms. The nitrogen stream is divided to subsidiary streams that are respectively fed into the head end of the combustors and that are mixed with a fuel to lower the modified Wobbe index to acceptable levels for the gas turbine.

Abstract: A method of generating electricity in synthesis gas in which a fuel is combusted in a gas turbine to generate the electricity that at least about 60 percent by volume is derived from a source independent of the synthesis gas. The synthesis gas is produced by reacting a hydrocarbon stream, by for example, partial oxidation, autothermal reforming or steam methane reforming. After the synthesis gas stream is cooled, heat is transferred from the heated synthesis gas stream to the fuel prior to combustion in the gas turbine. All or at least a portion of the heat is transferred at a temperature no greater than about 500° F. and at a flow ratio of the fuel to the gas turbine to the synthesis gas stream from at least about 1.5. The heating of the fuel to the gas turbine lowers fuel consumption and thereby the total expenses involved in generating electricity and syngas.

Abstract: A power augmentation method for a gas turbine in which water is injected into one or more stages of an auxiliary compressor to produce a vapor containing gas stream. The vapor containing gas stream is at least in part introduced into combustors of the gas turbine for power augmentation. Part of the vapor containing compressed gas stream can be introduced into a reactor to generate a hydrogen containing synthesis gas to support lower flame temperatures occurring within the combustors of the gas turbine due to the introduction of the vapor containing gas stream. In such manner, NOx emissions of the gas turbine can be reduced. Furthermore, the power augmentation method can be conducted in conjunction with an integrated gasification combined cycle.
