Abstract

1,259,826. Shaft furnaces. CHARBONNAGES DE FRANCE and HOUILLERES DU BASSIN DU NORD ET DU PAS-DECALAIS. 5 Sept., 1969 [6 Sept., 1968], No. 44169/69. Heading F4B. [Also in Division C1] An apparatus for the decarbonization of carbonaceous shales (Division C1) comprises a vertical furnace provided on its lateral walls with external casings 5 for the circulation of gases which casings are separated from each other by horizontal partitions 6 and communicate with the central chamber through elongate horizontal openings 3.
