furnace containing alloy tubes filled with catalyst. The gas is heated and reformed as it passes through the tubes. The newly reformed gas, containing 9092 percent H2 and CO, is then fed hot directly to the shaft furnace as reducing gas. Heat Recovery The thermal efficiency of the MIDREX® Reformer is greatly enhanced by the heat recovery system.
