Abstract
In a combustor () for a gas turbine, the combustor () includes a burner system () and a fuel supply system (). The burner system () includes at least two burner groups (A, B) each with at least one burner (). The fuel supply system () includes a main line (), which is connected to a fuel source (), and also an auxiliary line () for each burner group (A, B). Each auxiliary line () is connected to each burner () of the associated burner group (A, B) and is connected to the main line () by a controllable distribution valve (). A sensing system () measures pressure pulsation values and/or emission values for each burner group (A, B). A control system (), in dependence upon the pulsation values and/or the emission values, controls the distribution valves () so that in each burner group (A, B) the pulsation values and/or the emission values assume and/or fall below predetermined threshold values.
