Coal Gasifier Plant

Listing ID #3466729

Direct-reduced iron (DRI), also called sponge iron is produced from direct reduction of iron (in the form of lump, pellets or fines) by a reducing gases produced from natural gas or coal. This reduction takes place in the temperature range 800- 1050 degrees C when reducing gases; mainly Hydrogen and Carbon-monoxide; react with the iron oxides to produce iron. The degree of metallization, defined as the extent of conversion of iron oxide into metallic iron, is 92-96% in a typical DRI process. This high percentage of metallization makes DRI a highly suitable input for steel making. The specific investment and operating costs of DRI plants are low compared to integrated steel plants and are more suitable for many developing countries where supplies of coking coal are limited. This holds true for India where most of the coking coal has to be imported.
