Answer (1 of 13): Well, there are several parameters to be considered The quality of coal Since we are converting the energy in coal to electricity, we need to know the energy content of coal A quick googling tells me that the energy content of coal is given in terms of MegaJoules (Mj) p....

Description / Application / Shipment - Storage / Risk factors Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coalThe reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent...
World DRI production has seen continuous growth since the year 1970, and by 2011 the total production reached 733 million tons [49] Among various DRI processes, MIDREX dominates the market accounting for almost 60% of the total DRI production (MIDREX 444, HYL/EnergIron 111, Finmet 05, Coal-based 173 million tons in 2011, respectively)...
in 2017, with DRI/HBI production totaling only 168 million tons, which is well below the country’s installed capacity The limited production was due to many reasons, all of which are the result of the dire economic conditions of the country The Nu-Iron Plant in Trinidad and Tobago, owned by Nucor Steel....
DRI can be either hot or cold charged to the EAF Some steel companies ship DRI from their captive direct reduction plants to their remote steel mills and a small volume of DRI is sold to third parti In India there are many small rotary kiln furnaces producing DRI, known locally as sponge iron, using coal as energy and reductant source...
