Abstract

A combustion chamber with two-stage combustion has primary burners (110) of the premix type of construction, in which the fuel injected via nozzles (117) is intensively mixed with the combustion air inside a premix space (115) prior to ignition. The primary burners are of flame-stabilizing design, i.e. they are designed without a mechanical flame retention baffle. They are provided with tangential inflow of the combustion air into the premix space (115). Arranged downstream of a precombustion chamber (61) are secondary burners (150) which are designed as premix burners which do not operate by themselves.
