Abstract:
1. A burner for premix-type combustion comprising a cavity which has at least one tangential air inlet slot for the supply of a combustion air flow, means for the injection of fuel into the cavity, and means for the injection of premix fuel into the at least one air inlet slot which are provided centrally in the inflow region of the combustion air flow, wherein the means for the injection of premix fuel into the at least one air inlet slot includes at least one fuel supply having a first side and a second side and fuel outlet openings on the first side and fuel outlet openings on the second side, the premix fuel being introduced into the combustion air flow on the first and second sides of the at least one fuel supply in a cross-sectional plane at right angles to a burner axis; and the fuel outlet openings are provided upstream of the air inlet slots relative to a direction of the combustion air flow where a speed of the combustion air flow is less than a speed of a combustion air flow in the air inlet slots.
