    摘要: The invention relates to the method for burning lump material is in at least one shaft comprising a pre-heating zone, a burning zone and a cooling zone, wherein coal having a swelling index > 1 is supplied together with a transport medium via burner lances which have burner tips, via which the coal exits into the shaft together with the transport medium, wherein the temperature of the coal in the burner lances is kept below a temperature value at which melt phases of the coal form. Here, use is made of a transport medium for transporting the coal which transport medium forms a low-oxygen atmosphere in the shaft in the region immediately adjoining the burner tips, in order to delay the ignition of the coal following the exiting from the burner lance.
