1491645 Thermal processing of lump shale NI INST SLANTSEV and SLANTSEPERERABATY - VAJUSCHY KOMINAT "KOKHTLA - YARVE IM VI LENINA 1 April 1976 [1 April 1975] 13319/76 Heading F4B [Also in Division C5] A vertical retort for the thermal processing of lump shale comprises a low-temperature carbonization shaft 2, gasifying shaft 3 and a cooling shaft 4. The shaft 2 is divided by two vertical perforated walls 5 into two low-temperature chambers 6 and a chamber 7 for supplying and distributing a heat carrier some of which is generated from the burner 11 and gas supply 12 and some of which rises from the gasifying shaft 3. Lump shale is fed from the bins 13 to the hot side of chambers 6 next to chamber 7. The heat from chamber 7 produces a steam-gas mixture which rises and is filtered by the density of the bed so that it reaches the off-takes 17 in relatively dust free condition. The gasifying shaft 3 has side chambers with heat generated by burners 11 and gas supply 12. Semicoke produced in the chambers 6 is gasified in the shaft 3 and solid residue passes to the cooling shaft 4 where temperature is lowered by a cooling gas from a supply 18. Finally solid residue passes to the bins 19 and into liquid seal containers 20, whence it is discharged by conveying devices to ash heaps.
