Abstract
A steel making plant includes an electric arc furnace and a fume collection and treatment system. The system includes a first primary suction line fluidically connected to the electric arc furnace to suck fumes generated in the electric arc furnace. A secondary suction line is for ventilating the environment surrounding the electric arc furnace by a suction hood. A filtration apparatus is for filtering emissions collected by the fume collection and treatment system before they are discharged into the atmosphere. The electric arc furnace is powered by a continuous charging system. A fume cooling apparatus, a dust collecting device and a denox selective catalytic reduction apparatus are arranged in sequence along the first primary suction line, starting from the electric arc furnace. The secondary suction line flows into the first primary suction line downstream of the denox selective catalytic reduction apparatus and upstream of the filtration apparatus.
