Neutralizing of hazardous emission from electric steel furnaces with thermal and chemical treatment of waste gases

During the snowballing period of electrometallurgical production in the sphere of waste gas treatment there has been accumulated a number of problems that still have no satisfying solution or are principally unsolved. These problems are typical for all electro-metallurgical plants and in particular for plants with scrap pre-heating. These factors influence substantially upon cost efficiency and observance of environmental standards. To determine arrangements and purposes for further development in waste gas treatment sphere it is necessary to analyze their today's state. This article considers in brief the development state of hazardous emission neutralizing of electric steel making plants with thermal and chemical waste gas treatment.
