ABSTRACT:
On a burner for a gas-turbine combustion chamber which comprises a lean premix burner with centrally integrated stabilizing burner, a core air annulus (11) accommodating the atomizer nozzle (10) of the stabilizing burner is concentrically surrounded by a main air annulus (4) supplying the weak air-fuel mixture. In the adjacent issuing areas of the main air annulus and the core air annulus, a flame stabilization ring (13), which is heated by the combustion gases and whose cross-sectional surface increases in area toward the combustion chamber (5), is provided to produce an approximately hollow-cylindrical hot-gas recirculation zone (17) originating at the flame stabilization ring which ensures a stable flame formation throughout the range of operating conditions of the gas turbine.
