초록 ▼

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 combustion is conducted in the presence of an oxidation catalyst and the combustion zone including the catalyst is maintained at an approximately constant temperature. In a mode of operation which is preferred when conditions permit, such temperature is substantially above the instantaneous auto-ignition temperature of the fuel-air admixture but below a temperature that would result in any substantial formation of oxides of nitrogen. The resulting effluent is characterized by high thermal energy useful for generating power and may be low in atmospheric pollutants, including oxides of nitrogen.

A method for operating a gas turbine by combusting a carbonaceous fuel over a period of operation of said turbine during which the fuel demand or the combustion air temperature varies, comprising: a. forming an intimate admixture of said fuel and combustion air; b. substantially simultaneously controlling the ratio of said fuel to said combustion air in said admixture to maintain the adiabatic flame temperature of said admixture at about a preselected value; c. combusting at least a portion of the fuel in said admixture under essentially adiabatic conditions in a combustion zone, in the presence of a solid oxidation catalyst occupying a major portion of the flow cross section of said combustion zone, to form an effluent of high thermal energy; and d. passing said effluent to a turbine to rotate said turbine.
