The iron and steel industry generally features the characteristics of large volume of energy consumption, multiple sorts of energy medium, complex secondary conversion, more recyclable extra energy, and the energy management of the field may involve the entire personnel, process and system, covering all links from designing, purchasing, energy storage, processing and conversion, distribution, energy use and extra energy recycling. The implementation guidelines summarizes the energy management experience and results and provide a systematic approach for the implementation of GB/T 23331-2012 and GB/T 29456-2012, sharing svstematic instructions and suggestions for the implementing paths and methods of creating, implementing, maintaining and improving the energy management system (EnMS) at the enterprise level. 展开更多

The energy-saving management of China's cement industry has gradually improved in recent years; however, cement industry still faces big pressure of facilitating energy conservation and emission reduction. Based on the current development of cement industry, the paper summarizes and analyzes the application and promotion of energy management system(EnMS) standardization in cement industry, then gives a brief introduction to the implementation of related standards and at last explores the positive function of energy management system in enhancing enterprises' energy management and improving energy performance. 展开更多
