在机械产品生产过程中,大量消耗煤、焦、油、电、煤气、蒸汽、自来水等各种能源。国外先进工业国家的能源利用率,高的约57％,一般为45～50％。据估计,上海市许多行业的能源利用率约为30％左右,而机械行业的能源利用率只有25％左右,与国内外先进水平相比,差距很大。因此,提高机械行业的能源利用率、是当务之急。和电力等生产部门不同,能源在电力等部门中是作为“原料”消耗的,占生产成本的比重很大,迫使这些部门的工作人员去寻找提高能源利用率的途径,以降低“原料”消耗。而在机械工业中,能源是作为“燃
In the production of mechanical products, a large number of consumption of coal, coke, oil, electricity, gas, steam, tap water and other energy sources. The energy efficiency of foreign advanced industrial countries, high about 57%, usually 45 ~ 50%. It is estimated that the energy utilization rate of many industries in Shanghai is about 30%, while the energy utilization rate of the machinery industry is only about 25%, which is quite different from the advanced level at home and abroad. Therefore, to improve the energy efficiency of the machinery industry, it is imperative. Unlike electricity and other production sectors, energy is consumed as “raw material” in sectors such as electricity and accounts for a large share of production costs, forcing workers in these sectors to find ways to increase energy efficiency to reduce “raw material” consumption . In the machinery industry, energy is used as "fuel
