摘要： A system (S) for controlling nitrogen oxide (NOx) emissions and combustion pulsation levels of a gas turbine having a gas turbine combustion system, having a single combustion chamber and multiple burners, includes a cascade structure having a first and second control level (1, 2), the first level (1) having a device to control NOx emissions and generate combustion pulsation target levels based on the difference between measured and target NOx emission levels, and the second level (2) having a device to control pulsation levels and generate a ratio (γ) of fuel flow to different types of burners or to different stages of each burner. The fuel flow ratio (γ) is based on the difference between the measured and generated target pulsation levels. The control system (S) enables the operation of a gas turbine to meet NOx emission requirements, while maintaining combustion pulsation levels within limits that ensure improved lifetime of the combustion system.

摘要： A method for protecting a gas turbine installation from overheating and for detecting flame extinction in the combustion chamber is described, in which air is compressed in a compressor unit and, after being admixed with fuel, is ignited in the form of a fuel/air mixture in a combustion chamber and is burnt, thus giving rise to a hot gas flow which sets a turbine stage in rotation downstream of the combustion chamber so as to perform expansion work. The pressure upstream of the turbine stage, that is the pressure pk of the compressed air in the plenum and/or the pressure within the combustion chamber pcom, is measured, in that a time change of the measured pressure, what is known as the pressure gradient ({dot over (p)}), is determined, in that at least one threshold value is selected, and in that the pressure gradient or a variable derived from the pressure gradient is compared with the at least one threshold value and, if the threshold value is overshot or undershot, a signal is generated.
