Abstract
A combustion chamber (), in particular in a gas turbine, has at least two burners (A-H) that are connected to a fuel supply () via controllable fuel valves (' and). Each burner (A to H) is assigned at least one optical measuring device () for detecting chemiluminescent radiation, and the combustion chamber () is assigned a pressure sensor () for detecting a combustion chamber pressure. The optical measuring device () and the pressure sensor () are connected to a computing and control device, which calculates a correlation value from the incoming measured values. A high correlation value signifies that the associated burner is prone to pulsation. The computing and control device () is designed in such a way that it determines the burner or a burner group with the highest correlation and controls the associated fuel valve(s) in such a way that more fuel is fed to the respective burner or the respective burner group, and the pulsation tendency thereof is thereby reduced.
