  • Publication number: 20170044996
    Abstract: A method for operating a burner assembly, in particular a burner assembly of a gas turbine, wherein an evaluation variable representing the combustion stability is determined and at least one control variable is altered, at least based on the determined evaluation variable, when the determined evaluation variable does not fall within a previously defined desired range, the desired range of the evaluation variable being constant over the entire output range of the machine, and wherein the evaluation variable is determined based on measured maximum actual amplitudes in previously defined frequency bands and measured actual outputs of the burner assembly.

  • Patent number: 9557236
    Abstract: A method for controlling a gas turbine, wherein measurement signal values are measured at different times, namely at least a first time and a second time, wherein the first time lies before the second time and wherein attenuated signal values are generated from the measurement signal values by smoothing the measured measurement signal values by means of a attenuation factor, wherein a different attenuation factor is used depending on the difference of the measurement signal value at the second time and the attenuated signal value at the first time.

  • Patent number: 9464574
    Abstract: A method for running up a stationary gas turbine is provided. The turbine has a combustion chamber, the burners of which have a pilot burner and a main burner and by which various types of fuel are introduced into the combustion chamber for burning. The method, carried out while a rotor of the gas turbine is accelerating from a standstill to a nominal speed, includes feeding fuel of a first type of fuel to the pilot burners and feeding fuel of the first type of fuel to the main burners. In order to provide a method in which a comparatively low supply pressure is required in the fuel supply system and in which combustion vibrations that put the machine at risk are avoided during the running-up process, it is proposed that fuel of a second type of fuel is fed to the burner before the nominal speed is reached.

  • Publication number: 20160010566
    Abstract: A method for operating a gas turbine below its rated power, in which CO emissions in the exhaust gas of the gas turbine increase with a reduction of the output gas turbine power, wherein, if a predefined threshold value, which can be selected as desired, for the CO emissions is reached or if a predefined threshold value, specified in relative or absolute terms, for the output gas turbine power is undershot, the combustion temperature in the combustion chamber of the gas turbine is increased. To operate the gas turbine with low emissions, for a constant power output, the exhaust-gas temperature increase generated at the outlet of the gas turbine as a result of the combustion temperature increase is at least partially compensated through the addition of a liquid or vaporous medium.

  • Patent number: 6490867
    Abstract: A method of operating a burner, in particular, a burner of a gas turbine, and a burner configuration include supplying an adjustable burner with fuel through a supply line. The fuel quantity is set by an opening of a control element as a function of a selected output of the burner. A calorific value of the fuel is determined, and the degree of opening is calculated and directly set using the output and the calorific value, resulting in a variable output control that is operationally reliable with respect to perturbations. A controller is connected to the control element having a selectable opening for setting the fuel quantity. In the controller, the degree of opening can be determined as a function of the output, the type of the fuel, and a pressure loss in the fuel supply line, and a corresponding signal can be transmitted to the control element such that the degree of opening is set.
