ABSTRACT:
In a burner of the double-cone design for burning liquid (12) and gaseous fuels (16), the at least two sectional cone bodies (1, 2) overlap at least partly, the overlap angle (.delta.) increasing in the direction of flow of the burner, and the distance between the fuel injectors (15) and the air-inlet plane (21) into the burner increasing simultaneously with the increase in the overlap angle (.delta.). As a result, the air-inlet plane (21) and the fuel-injection plane (22) no longer coincide. Improved premixing of the gaseous fuel (16) with the combustion air is achieved by the invention, which leads to lower NOx emissions of the burner and to lower thermal loading of the burner front.
