7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

Most of the recent developments in blast furnace gas cleaning technology have been based on dry gas cleaning systems. Danieli Corus has developed a new system, applying proven technology available within the Danieli group for dry cleaning of e.g. EAF, DRI, BOF and aluminium smelter gases. This new system consists of a gas conditioning tower, reagent injection system and (pressurized) filter modules with low pressure pulse cleaning. The system was designed for a residual dust content below 5 mg/Nm³ and for increased TRT output and calorific value of the blast furnace gas. For wet blast furnace gas cleaning systems, Danieli Corus introduces a new type demister to replace existing demisters. This type of demister is more compact and has a smaller footprint while offering a higher removal efficiency. This new demister requires lower investment while offering a higher calorific value of the blast furnace gas.
