System and Method for Fuel and Air Mixing in a Gas Turbine

Abstract

A gas turbine system including a source of gas coupled to a source of fuel wherein the gas and the fuel are combined to form a mixture of gas and fuel prior to the mixture being introduced to a fuel nozzle of the gas turbine system.

1 . A method for operating a gas turbine, the method comprising:
 receiving gas from a source of gas;   receiving fuel from a source of fuel; and   mixing the gas with the fuel to form a mixture of gas and fuel prior to the mixture being introduced to a fuel nozzle of the gas turbine.   
     
     
         2 . The method of  claim 1 , wherein the mixture is non-combustible. 
     
     
         3 . The method of  claim 1 , wherein the method is implemented by a computer program product stored on machine-readable media and comprising machine executable instructions for operating a gas turbine, the product comprising instructions for:
 receiving the gas from the source of gas;   receiving the fuel from the source of fuel; and   mixing the gas with the fuel to form a mixture of gas and fuel prior to the mixture being introduced to a fuel nozzle of the gas turbine.   
     
     
         4 . The method of  claim 1 , wherein the gas includes air. 
     
     
         5 . A method for operating a gas turbine system, the method comprising:
 receiving gas from a source of gas;   receiving fuel from a source of fuel; and   combining the gas and the fuel in a portion of a fuel line connected to fuel nozzle of the gas turbine system to form a mixture of gas and fuel prior to the mixture being introduced to the fuel nozzle of the gas turbine system.   
     
     
         6 . The method of  claim 5 , further comprising:
 measuring a rate of flow of the fuel in the fuel line; and   regulating a flow of the gas from the source of gas responsive to the measured rate of flow of the fuel in the fuel line.   
     
     
         7 . The method of  claim 5 , wherein the rate of flow of the fuel in the fuel line is measured with a sensor. 
     
     
         8 . The method of  claim 5 , wherein the flow of the gas from the source of gas is regulated with a control valve. 
     
     
         9 . The method of  claim 5 , wherein the gas includes air. 
     
     
         10 . The method of  claim 5 , wherein the gas includes air and at least one of carbon dioxide, additional nitrogen, and steam. 
     
     
         11 . The method of  claim 5 , wherein the fuel is in at least one of a gaseous state and a liquid state.
