FIELD: active carbon production. SUBSTANCE: proposed furnace has housing accommodating cylindrical retort, heating elements in form of gas burners, charging and discharging devices and branch pipes for supplying gaseous reagents. Axis of gas burners is displaced relative to axis of retort through 0.9-1.2 of its radius. Furnace chamber is provided with branch pipe to let out heating gases which is arranged at a distance equal to 0.23 - 0.30 of its length. EFFECT: increased overhaul period of furnace, reduced heat losses, improved homogeneity of quality indices of obtained products. 2 cl, 2 dwg
