ABSTRACT OF THE DISCLOSURE A burner for combustion of powdery fuels. The burner a core-air tube with a centrically arranged ignition device, a dust tube surrounding the core-air tube, and a mantle-air tube which surrounds the dust tube and is pro- vided with an axially displaceable twist blade ring or impeller, arranged at its air inlet, as well as a burner opening which widens conically toward the combustion chamber. A dust-ignition burner is arranged concentrically in a core- air tube, and comprises an ignition-dust tube arranged con- centrically around the ignition, and a mantle-air tube which surrounds the ignition-dust tube for the ignition- dust flame and is provided with an axially displaceable twist blade ring or impeller, arranged at its air inlet, as well as a conically widening outlet. The conical angle of the dust-ignition burner outlet is equal to or greater than the conical angle of the outlet of the main burner. The dust-ignition burner outlet terminates before the be- ginning of the conical widening of the main burning.
