Siemens will be responsible for the design, supply and installation of the Simetal ECO Prime Cooler, the dual flow nozzle spray system for the evaporative cooler, and a new hood car. The converter offgas will be collected in the cooling stack installed immediately above the converter. The gas must be cooled and pre-cleaned to prevent damage to downstream facilities. The waste heat transferred from the converter gas during cooling will be used to partially vaporize circulating water to produce saturated steam. Siemens will install new dual flow sprays to atomize the water in the evaporative cooler. These will enable improved conditioning of the dust in the converter gas and thus allow optimum operation of the evaporation cooler thanks to precise regulation of the water-steam mixture. A traversable, locking mechanical seal is also part of the scope of supply. It requires little maintenance and has a long service life.

 

Siemens will also renew the piping in the steam system and replace some of the field devices and instrumentation. Siemens and ArcelorMittal will make the necessary modifications to the platforms and steel structures. The project also includes dismantling the previous equipment and supervising the installation and commissioning work.
