Compression of blast furnace gas
WebIt should be noted that under these conditions plasma is obtained only due to the gas-dynamic heating of gas by means of shock waves and due to the shock-free compression of gas [4,5,6,7]. The gas-dynamic method for high-enthalpy plasma obtained in explosive generators is a distinctive feature compared to the prevailing methods of electrical ... WebThe DFB-DR path is the only route considered that allows negative CO2 emissions, enabling a 145% decrease in emissions relative to the traditional blast furnace–basic oxygen furnace (BF–BOF) route. A reducing gas cost between 45–60 EUR/MWh is obtained, which makes it competitive with the hydrogen route, but not the natural gas route.
