FIELD: production of activated carbon for carbonization of starting vegetable material before activation (wood, nut-shells, fruit kernels); wood-chemical industry for production of raw coal and other carbon-containing materials.
SUBSTANCE: proposed furnace has body (1), cylindrical retort (7), heat insulation, heating chamber, loading and unloading units located along body axis, gaseous product inlet branch pipe (11) and outlet branch pipe (19). Body (1) is mounted on swivel supports (3) and is provided with taper end faces (2). Located vertically inside retort (7) is heat-transfer agent inlet branch pipe (11). This branch pipe is located at height of 0.6-0.75 of its diameter and is provided with perforated cover (12) and ports (13). Outlet branch pipe (19) is mounted in lower part of retort (1). Loading and unloading units are made in form of hatches (9). Heating chamber is made in form of firebox (14). Yield of finished product - carbonized vegetable material is increased by 1.1-1.3 times and productivity is increased by 1.5-2.0 times per unit volume.
EFFECT: increased yield of finished product; increased productivity.
