Abstract
In a combustion chamber with at least one premixing burner (110) which is fastened by means of its burner outlet (118) to a front plate (54) bounding the combustion space of the combustion chamber (60), the gaseous fuel is introduced via gas inlet flow openings (117) arranged around a burner axis (100). The fuel is mixed with the combustion air prior to ignition. The fuel concentration at the burner outlet (118) is lower at the outer edge of the flow field generated by the premixing burner (110) than it is in the inner part of the flow field. The temperature of the combustion gases at the outer edge of the bonnet-shaped reverse-flow zone (121), which gases impinge on the combustion chamber wall (63), is lower than the average temperature of the combustion gases in the bonnet-shaped reverse-flow zone (121).
