Abstract

Method for the combustion of vanadium-containing fuels that makes use of the extremely high reactivity of the vanadium-containing fuels for combustion in a dust furnace. To avoid disadvantageous slag caking in a combustion area and in particular in the vicinity of the feed nozzles, e.g. for the pulverized fuel-air mixture and for combustion air, in a dust furnace, a top burner is placed in a roof of a combustion area and at least open dust nozzel is so positioned for the supply of the pulverized fuel-air mixture that a return flow of liquid slag particles to the top burner is prevented.
