    摘要： A hearth furnace for producing direct reduced iron is described. The furnace has first and second combustion chambers, each having a rotating hearth within it to receive iron oxide and reducing agent. A set of rabbles disposed over each of the rotating hearths interacts with the iron oxide and pushes the iron oxide towards an inside or an outside edge of each rotating hearth. The first combustion chamber having an outlet connected to an inlet of the second combustion chamber to receive materials pushed by the rabbles of the first combustion chamber to the first combustion chamber outlet. The furnace further comprising one or more gas transfer channels for transferring reduction gasses and heat between the second and first combustion chambers.
