ABSTRACT:
A device and a method for burning fuel in air. The device includes an annular passage for directing the air in a meridional flow with regard to an axis. A swirl cascade is provided for imposing a swirl on the flow, and a mixer for intermixing the fuel with the flow for forming an essentially homogeneous mixture. Also present is an air flow delayer for delaying a portion of the flow that lies radially on the outside with regard to the axis relative to other portions of the flow. The device is configured in particular as a premix burner, for example for use in a gas-turbine plant.
