UTILIZATION METHOD OF COKE OVEN GAS OR COAL GASIFIER GAS

摘要

PURPOSE: A utilization method of coke oven gas or coal gasifier gas is provided to diminish use of coal cost and the generation of the CO 2 by using heat of the reducing gas of high temperature. CONSTITUTION: A utilization method of coke oven gas or coal gasifier gas is as follows. The reducing gas of high temperature exhausted from the coke oven or the coal gas burner is partly oxidized to steam and oxygen. The heat of the oxidized reducing gas is exchanged through a plurality of heat exchangers. The reducing gas exhausted in the heat exchanger' is blown into a flowpath to fine ore.
