Abstract

In a method for the ignition of a fuel dust power burner, in which the ignition energy is provided by a fuel dust pilot burner, for example for the ignition of a coal dust burner with a coal dust igniting flame, the ignition performance of the igniting flame is not adequate in some cases. In order to increase the ignition performance, so as also to be able to ignite the flames of high-powered power burners, it is proposed that, after ignition of the igniting flame to which coal dust and air are supplied by respective tube, a mixture of additional igniting coal dust supplied by way of a further tube and air is conducted to this flame by way of the power fuel dust tube, and then the power fuel dust is supplied along the power fuel dust tube.
