    • A method and apparatus for operating a gas turbine system are disclosed utilizing an adiabatic combustion process, employing combustion of a pre-mixed carbonaceous fuel-air admixture in a combustion zone. The combustion and the combustion zone are maintained at an approximately constant temperature by selective control of the fuel-to-air ratio over a period of turbine operation during which the fuel demand or the combustion air temperature varies. Such control of the combustion zone temperature is such that said constant temperature is substantially above the instantaneous auto-ignition temperature of the fuel-air admixture. The resulting effluent is characterized by high thermal energy useful for generating power and may be low in atmospheric pollutants, including oxides of nitrogen.

    • Carbonaceous fuel is thermally combusted with an amount of air substantially less than that needed for complete combustion to carbon dioxide and water of all the combustible components in the fuel to produce a gaseous first effluent containing a substantial proportion of carbon monoxide but little or no nitrogen oxides. The first effluent is mixed with additional air and at least a portion of the resulting mixture is passed into the presence of a solid oxidation catalyst for combustion at a temperature above the instantaneous auto-ignition temperature of the mixture but below nitrogen-oxide-forming temperatures. Heat is withdrawn from the initial thermal combustion stage and from the gases downstream of the catalyst for the purpose for which the furnace is being operated.
