Abstract

Industrial growth and Environmental damages as two important indicators in sustainable development are followed by steel industry. This article is mainly dealt with addressing the quality. In this case, energy, material, capital consumption and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally suitable dust collector for different furnace tonnages. In this way total cost in 3 mentioned dust collectors were calculated in four furnaces with capability of 1, 3, 6 and 12 tonnages. The results indicate that the total costs of dust collectors in one ton furnace during 20 years are respectively 7926.47 in Electrostatic Participator, 19921.60 in Bag Filter and 18217.08 in Venturi Scrubber and the costs in 3-ton furnace reach respectively to 25811.19, 64407.72 and 50499.58 dollars. In 6-ton furnace the costs are 51652.42, 128815.46 and 119699.33 dollars, therefore in 12- ton furnace, the costs extend to 103622.4, 257630.56 and 243783.53 dollars. It can be concluded that Venturi Scrubber dust collector for 3-ton and less capability furnaces is the most suitable option in terms of environmental sustainability and industrial ecology. But for the capacities beyond 3 tons, the usage of Bag Filters and Electrostatic Participator dust collectors are more suitable.
