Abstract:
A burner system, comprising:a premix burner having at least one vortex generator, through which passes an air-containing gaseous main flow, the main flow flowing axially through the premix burner; means for injecting gaseous and/or liquid fuel into the premix burner, said injecting means being arranged downstream of the vortex generator, as a secondary flow for generating a fuel/air mixture; a combustion chamber arranged downstream of the premix burner, said combustion chamber having a cross section which is larger than a cross section of the flow, said flow cross section being defined as the cross section of the premix burner; and a flow duct arranged between the premix burner and the combustion chamber, said flow duct being delimited by side walls which create a gradual transition between the flow cross section and the combustion chamber cross section, and wherein upstream, within and/or downstream of the flow duct is provided at least one flow stall structure, by means of which the fuel/air mixture passing through the flow duct is separated locally from the side walls of the flow duct.
