Abstract
In this paper, economic and industrial parameters of Karabuk city have been assessed, a detailed comparison of production sectors has been done and several designations have been made on energy waste in the energy-intensive steel industry. 22% of total industrial facilities in Karabuk produce steel and its derivatives, but 90% of the total energy is used by steel production industry. Steel production needs high energy consumption. At the production process of steel, high efficient electrical energy converts into low efficient thermal energy. This transformation brings a high rate of energy loss. By increasing energy need in the world, those who are concerned maintain energy saving attempts and designate energy loss ratios of energy systems. In this study, specifications of energy wastes of energetic systems have been estimated and energy efficiency potential of various energetic systems has been evaluated. Assessments have indicated that 20 to 45%, 25 to 35%, 20 to 45%, 20 to 40%, 15 to 30%, 15 to 45%, 10 to 30% of average current energy in steel, textile, food, chemical process, mining, casting and cement and other sectors can be conserved, respectively. Key words: Energy waste, steel production, energy conversion, Karabuk, Turkey.
