  • Anti icing method and apparatus
    Patent number: 11053849
    Abstract: A method of reducing applied heat within an inlet duct of a gas turbine generating electricity includes applying heat to the inlet duct of the gas turbine to attain an initial temperature set point and to produce conditions sufficient for preventing formation of ice within the inlet duct, measuring a position of an inlet guide vane (IGV) of the gas turbine, an inlet duct temperature, and an inlet duct relative humidity to determine a thermodynamic state in the inlet duct, evaluating the thermodynamic state to determine if the conditions are sufficient for preventing formation of ice within the inlet duct, and in response to determining that sufficient conditions exist within the inlet duct for preventing formation of ice, adjusting the applied heat to maintain the measured inlet duct temperature.
