Natural gas cannot be used directly in the reduction of iron ore because it decomposes to form soot at a temperature below that which iron oxide can be reduced. Natural gas is used in three main ways: First, as a feedstock for producing the reducing gas, second as a fuel for supplying the necessary heat in the furnace and gas reformer, and third as a coolant and carburizing agent for freshlyprepared DRI.

The coalbaseddirect reduction conceptutilizing the rotary hearth furnace is a simple one. The RHF consists of a flat, refractory hearth rotating inside a stationary, circular tunnel kiln. Inside the RHF, direct reduction of iron oreor ironbearingbyproductsoccurs,usingcoalas the reductant. For decades, rotary hearth furnaces have

The product of such solid state processes is called direct reduced iron. Direct reduction processes can be divided into two categories: gasbased, and coalbased. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1200 °C)
