Coal Gasification OptionAn alternative option generating significantinterest in India is the use of a coal gasificationplant in combination with a Direct Reductionplant. The coal gasification plant would uselocal Indian coals to generate a synthesis gas (orsyngas) that can be an acceptable reducing gassource for producing DRI in a shaft furnace.

The 75% of DRI or HBI is produced with processes based on natural gas as energy resource, which has to be converted by gas reforming technology to reducing gases (CO and H 2) for the reduction of iron oxide to metallic iron. In the present chapter, the different plant layouts are described.

Of total DRI the production in 2008, 74 percent was produced from coal and 26 percent from natural gas. India is now the world's largest producer of DRI. Currently, there are two primary means of DRI production in India: smallscale rotary kilns using coal and iron ore lump, and largelocal scale shaft furnace plants using
