INTRODUCTION The tunnel kilns are mostly used by the ceramic industries for heating refractory and ceramic products [1-2]. In the year 1908 use of tunnel kiln started for iron Commercial DRI plants currently use natural gas, which is reformed to be more hydrogen intensive, while sponge iron may be produced via coal-fired rotary kilns. New iron developer FerroSilva said May 4 that it has developed a new biomass-based process for renewable metallic iron, targeting a 50,000 mt/year plant to be completed in 2026 inIron ore briquettes, lump, biomass DRI may ease steel

South Africa has recently shifted its export focus to Asian countries after European demand for the fuel dropped. India generally procures South African low-mid grade coal to cater to the requirement of the sponge-iron sector. "Indian buyers' imports are mostly mid/low cv coal with regular demand," a Pakistan-based trader said.Energy survey of the coal based sponge iron industry,. Case Studies in Thermal Engineering. 2015; 6: 1-15. mostly in South America, Africa, and the Asia-Pacific region.

Solid-based direct reduction of iron ore requires the reductant coal to have a suitable CO 2 reactivity to achieve optimum pre-reduction within a rotary kiln. The CO 2 reactivity is affected by numerous factors including coal properties and operating conditions, and is traditionally determined using pulverized samples. The CO 2 reactivity The global direct reduced iron market is estimated to garner a revenue of ~USD 62 billion by the end of 2035 by growing at a CAGR of ~7% over the forecast period, i.e., 2023 2035.

The Mozambique coal, typically loaded from the Maputo port, has high sulfur content and comes in a near-powder form, making it unacceptable for sponge iron and metal industries, sources said. "Cement companies can use the coal from Mozambique because of the higher sulfur content and it is a good alternative to petcoke," an India Abstract Solid state reduction of an Australian chromite with black coal and silica addition was studied thermogravimetrically in the temperature range 1000–1400°C under an argon atmosphere. Reduction was found to occur in two stages. In the first stage, reduction is initiated by the nucleation of metallic iron, and the rate is likely to be Kinetics of solid state silica fluxed reduction of chromite with coal

The paper focuses on the evolution of the South African iron and steel industry from the industrial engineering perspective. The earliest ironmaking in South Africa dates to the fifth century CE; but the major evolution of the industry began in 1882 and, by the year 1934, steel production from native ore was in full swing.To produce 1,000 kgs sponge iron, around 800 kg of Mozambique coal is required against 1,500 kg of Indian coal .
