FIELD: metallurgy. SUBSTANCE: plant for cleaning metal chips of organic impurities has drum furnace whose inlet is connected to feeder supplying dirty chips, device for preparation of gaseous heat- transfer agent provided with at least one burner whose outlet is hot-connected to furnace space, smoke exhauster and pipe line for recirculating the combustion products through drum furnace in counterflow relative to chips being cleaned and branch pipe for discharging excessive combustion products to atmosphere. Recuperative cooler (mainly this is two-stage cooler) for cooling the combustion products is mounted after the burner; smoke exhauster and recirculation pipe line are connected to inlet and outlet of this cooler through branch pipes equipped with flow regulators. EFFECT: enhanced efficiency. 4 cl, 1 dwg
