1.关于节约能源的认识 钢铁企业开展节能工作是发展钢铁工业的大方向,但节能效果受到国家与企业的财方、物力以及当前技术水平的限制。如我国这几年采取关停并转一批耗煤、油、电大的地方钢铁企业,节能成效较为显著;狠抓能源管理上的“浮财”后成果也不小。但随着节能工作的逐步深入,节能难度就愈来愈大。例如,一座耗能大的后进工业炉,其热效率为
1. Understanding of energy conservation Steel companies to carry out energy-saving work is the general direction of the development of the steel industry, but the energy saving effect by the state and business financial and material resources, as well as the current state of the art restrictions. For example, in our country, the local steel companies that shut down and transfer coal, oil and TV sets have achieved remarkable energy-saving results. The achievements in energy management are not negligible after paying close attention to energy management. However, with the gradual deepening of energy-saving work, energy saving becomes more and more difficult. For example, a large energy-consuming backward industrial furnace has a thermal efficiency of
