The challenge imposed by limited DR-grade iron ore supply on plans for a large global scale-up of DRI production is significant. To avoid locking in further coal-based steelmaking capacity for decades, some technology switching to DRI processes will be required before 2030 to achieve net zero by 2050.

TUNNEL KILN (Coal-based DRI Plant) Production of sponge iron by Tunnel Kiln technology was developed in 1911 as Höganäs method. Now very popular, the technology has become an effective method for sponge iron production. With the Tunnel Kiln technology, it is possible to build small plants with low investment costs.

This new plant has an initial production rate of 675,000 metric tons per year of DRI. Operating results of the 4M plant, for production and DRI quality, are presented in Figures 4 and 5 respectively. Being the first-of-its-type industrial installation, some routine operation interruptions have taken place, mainly for equipment monitoring.

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 coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.

DRI is produced through the removal (reduction) of oxygen from iron ore in its solid state. This technology encompasses various processes based on different feedstocks, reactors, and reducing agents. DRI processes can reduce CO 2 emissions by using natural gas instead of coal due to the replacement of carbon reductant by hydrogen from the …

Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

The employed fuels are natural gas and/or coal. The energy consumption is in the order of 10.4 GJ/t-DRI that is equivalent to 300 m 3 of natural gas per ton of reduced iron. The CO 2 emissions are quantified in the range 0.77–0.92 t of CO 2 per ton of steel. As a function of the employed reducing reactors, the systems are of four main types:
