Waste Gas Cooling Plant Hisarna Process

An example for the Direct-reduction process systems is the Hlsarna process, which was developed as part of the ULCOS project (Ultra-Low Carbon Dioxide [CO2] Steelmaking). This has the goal of halving the carbon dioxide emissions in steel production. Oschatz built waste gas cooling sections in connection with the HIsmelt process for the first time in 2005; these have been successfully used in the HIsarna process since 2011. This forward-looking process combines the preheating and partial pyrolysis of the coal in the reactor, the melting cyclone for melting iron ore and the melting crucible for subsequent reduction of the iron ore and iron extraction. The consumption of coal is thus reduced, which results in a significant cut in carbon dioxide emissions. The round design conceived by Oschatz. provides a particular contribution to ensuring maximum efficiency in the production of steel.
