A method for burning lumpy stock is performed in at least one shaft which comprises a preheating zone, a burning zone and a cooling zone. Coal with a swelling index>1 is supplied together with a transport medium via burner lances which have burner tips. The coal together with the transport medium emerges into the shaft, wherein the temperature of the coal in the burner lances is kept below a temperature value at which melt phases of the coal that is used are formed. Here, for the transportation of the coal, use is made of a transport medium which, in the shaft, in the region directly adjacent to the burner tip, forms an oxygen-depleted atmosphere in order to delay the ignition of the coal after it emerges from the burner lance. |
