Abstract
It was found that dust of electrostatic precipitators supplied to the sintering furnace from the hot end precipitates little on the sintered material of the raw charge of alumina production of JSC "RUSAL Achinsk", increases the dust turnover and dust release of solid pollutants from the furnace into the atmosphere. In order to increase efficiency of purification of atmospheric air from fine dust of electric precipitators it is proposed to remove it from dust circulation of the sintering furnace and dispose of it separately in technology of road mixture when laying the base of road pavements. The introduction of this technology provides a reduction in atmospheric emissions from 18.965 to 5.859 g/s, a reduction in coal consumption by 1.39 kg of conventional fuel for the production of 1 ton of sinter and savings of coal fuel by 8350 tons per year.
