钢铁企业余热余能转换或替代电能的途径

钢铁企业是用能大户,利用余热余能技术发电或替代耗电设备可有效降低电能消耗,减少企业外购电能。余热余能转换成电能的主要途径有可燃废气通过燃烧发电,燃气—蒸汽联合循环发电,烧结余热发电,转炉轧钢加热炉发电等。替代电能的主要途径有汽轮机拖动风机旋转等。这些措施为钢铁企业实现节能降耗提供了有效途径。

国内外钢铁工业能耗现状和发展趋势及节能对策

重点研究了能源利用方式粗放、浪费严重、效率不高的问题,技术已经成为制约行业发展的瓶颈,受资金和技术条件限制,一部分技术装备水平低、消耗高、环境污染严重的中小企业,将面临被淘汰和被兼并的命运。利用新技术是当前节能工作的重点。

无功补偿技术在宝钢供配电系统的应用

无功补偿是提高用电负荷功率因数、降低电网线损的一种普遍应用的重要节电措施。主要讨论和分析了无功补偿技术在宝钢二原料变电站的应用情况,并对节电效益进行了计算,对类似工业企业电网变电站的无功补偿问题具有重要的参考意义。

The Applications of High-voltage variable frequency speed regulation System in Main Exhauster of Sintering

Main Exhauster is one of the main equipment of sintering production. It needs to consume a lot of electricity. Therefore, the system＇ s reconstruction for energy-saving will effectively reduce electricity for the production. The paper takes an iron and steel enterprise that had successfully transformed the synchronous motors of main exhauster of sintering as an example, which describes the application of high-voltage variable frequency speed regulation system in main exhauster of Sintering, so as to provide a reference for other iron and steel enterprises.
