本文根据钢铁企业现状,分析了钢铁联合企业佘能余热回收利用情况,结合“十一五”规划研究对用电能形式回收余能余热进行了计算,指出钢铁联合企业在不额外购入能源发电的前提下“做到电力自供有余,实现外供”是不可能的,同时得出了全部依靠余能的自发电量占钢铁企业耗电量的比例上限。
Based on the status quo of iron and steel enterprises, this paper analyzes the situation of recycling and utilization of residual heat in steel and iron combined enterprises. Based on the study of Eleventh Five-Year Plan, Under the prerequisite of energy power generation, “it is impossible to make electricity self-sufficient and external supply”, and at the same time, it is concluded that the proportion of self-generating electricity that accounts for the surplus electricity of the iron and steel enterprises accounts for the proportion of power consumption of the iron and steel enterprises.
