ABSTRACT:
A control system is provided to prevent flashing of crude oil fuel at the burner nozzles of a combustion gas turbine. The discharge pressure of the combustion gas turbine air compressor is monitored to determine if the combustion gas turbine is operating in a potentially nozzle-flashing manner. If the combustion gas turbine system is operating in a potentially nozzle-flashing manner then the vapor pressure of the crude oil fuel to the combustion gas turbine is lowered. If no potential for nozzle flashing exists, then the vapor pressure of the crude oil fuel can remain at a higher level. Control of the vapor pressure of the crude oil fuel in response to the combustion gas turbine air compressor discharge pressure provides maximum use of the crude oil as fuel while minimizing the venting of light hydrocarbons from the crude oil fuel to reduce the vapor pressure of the crude fuel oil.
