系统节能是以系统工程学的方法,求得该系统内的用能结构最优化,从而达到系统整体能源利用的最佳化结果。它虽然在单项上需要投资采取一定的节能措施,但更多的依靠科学方式即软件的力量进行优化组合,从而可以取得投入少而节能效果大的结果。随着节能工作的深化它应该是今后发展的重点。一、系统节能主要内容 (一)企业系统节能可以耗能高而企业内部结构复杂的钢铁联合企业的吨钢可比能耗说明如下。年产钢300kt的杭钢比年产钢6000kt的鞍钢,由于规模效益的影响,工序能耗普遍比鞍钢高,但由于炼铁系
The system energy conservation is a system engineering method, and the optimization of the energy consumption structure in the system is achieved, so as to achieve the optimization result of the overall energy utilization of the system. Although it needs to invest in certain energy-saving measures on a single item, it depends more on the scientific method, that is, the power of the software to optimize the combination, so that it can obtain results with less investment and large energy-saving effect. With the deepening of energy-saving work, it should be the focus of future development. I. Main contents of system energy conservation (1) The comparable energy consumption per ton of steel in the iron and steel conglomerates with high energy consumption in the enterprise system and complex internal structure of the enterprise is described below. Anshan Iron and Steel with an annual output of 300 kt of steel is higher than Anshan Iron and Steel, which has an annual output of 6,000 kt of steel. Due to the impact of economies of scale, the energy consumption of the process is generally higher than that of Anshan Iron and Steel, but due to the iron-smelting system
