| Resumen |
When one metric ton of steel is refined in an electric arc furnace, 80-90kg of carbon monoxide, approx. 10kg fine dust, as well as sulfur monoxide, nitrogen and other substances are set free. The effectiveness of exhaust hoods rarely exceeds 70%. Description of a two-zone system which enables an effectiveness of 93-95% to be attained by exhausting 16,000-18,000m3/h (t=80°C): In the first zone, the gases are drawn from the charging door, and in the second, through the openings in the roof round the electrodes, from where the gases pass into a telescopic and articulated duct allowing the furnace to be tilted. While the gases are exhausted, air penetrates into the furnace and helps to burn part of the carbon monoxide. |
