METHOD AND APPARATUS FOR CHARGING ORE INTO HIGH-PRESSURE REACTION VESSEL

摘要

FIELD: ore charging equipment and method. SUBSTANCE: method involves feeding heated ore into high-pressure transfer vessel 35,36; compressing ore by compressed gas and transferring it to high-pressure reaction vessel 1 through feeding pipeline 5 by compressed gas. Ore is continuously charged into reaction vessel 1 by alternative feeding of ore from one transfer vessel 35 and from other transfer vessel 36. Compressed gas is supplied from reaction gas reservoir in predetermined amounts and returned back together with ore. EFFECT: increased efficiency, optimum usage of reaction vessel, uniform charging of ore, efficient metal reduction and enhanced reliability in operation.
