E.ON Polska has completed the construction of a heat recovery system at ArcelorMittal Poland’s plant in Dąbrowa Górnicza. The new technology is already fully operational and provides significant energy savings, and is undergoing final warranty tests.
The innovative solution allows the use of flue gas energy with an average temperature of up to 250°C, which is returned to the production process. This allows fuel gas and air to be heated up to 180°C, which leads to a reduction in CO2 emissions by 56 thousand tons annually, the recovery of 117 GWh of energy, and a reduction in coke consumption by 10 thousand tons per year.
The implementation of this system was made possible by the strategic partnership between E.ON EIS Polska and ArcelorMittal Poland, which already includes eight energy efficiency projects.
This is the major investment in heat utilization in the steel industry in recent years. The company is evaluating the possibility of implementing similar solutions at other enterprises.
