Process for the operation of an annular combustion chamber, and annular combustion chamber

摘要

A process is described for the operation of an annular combustion chamber (13) and also an annular combustion chamber (13) with numerous circularly arranged premix burners (1, 2), in which, respectively, a fuel-air mixture is produced before it is ignited and is used as a hot gas stream to drive at least one turbine stage of a gas turbine plant. The invention is distinguished in that at least one premix burner (2) is operated such that it has a spatial mixing profile deviating within the fuel-air mixture from all other premix burners (1).
