Energy Management in a Steel Plant...

Energy Management in a Steel Plant Iron and steel industry is the largest consumer of energy among all industrial sectors. Energy conservation in steel industry is crucial for its competitiveness, sustainability and minimization of environmental impacts including green house gas emissions and better resource management. As per World Steel Association, energy costs represent around 20 % to 25 % of the total input of steel plants. Energy cost cutting and energy efficiency improvements are the most important topics of control for the steel plant management.  Energy management provides the following opportunities in a steel plant. It provides opportunities to decrease the energy intensity per ton of crude steel It provides opportunities to adopt best or good practices for utilization of energy sources more effectively It provides opportunities for using best or good practices for recovery of heat and gas energy wherever practical. It enables the plants to develop plans for reduction of plant’s energy intensity It makes plant to carry out prioritization of those investments which have biggest impact on the energy efficiency. Energy management efforts, which aim to reduce energy use, are a must as well as a key element for a steel plant’s energy management programme. Twin approach for energy management in a steel plant is desirable and necessary. Energy management programme can be system based through implementation of ISO 50001-2011 standard as well as it can be a technical approach based on real time information obtained from process monitoring and control systems and on production plans received from production planning systems. While the first approach is a management approach which streamlines all the systems connected with energy use and energy conservation, the second approach provides information on actual and planned energy indicators of production, distribution and consumption on real time basis...
