The direct reduction technology includes such euipments as oxygen station, gas generator, pressure change CO2 adsorption device and reduction furnaces. The characteristic is as follows: the reducing gas is prepared from coal (or coke) oxygen and CO2. Reduced tail gas, after pressure change and CO2 adsorption, is reused cyclically, or after dust removing, is reused for electricity generation; there are more than four reduction furnaces, they are arranged in cyclic operation. It is used for producing reduced iron and features low energy consumption, less pollution, less investment, simple construction of the reduction furnace, reliable production, it uses coal or coke instead of natural gas. |
