我国机械工业耗能量大约占全国总能耗的5.5％,其中电能消耗量约占全国总电能消耗量的7.4％,机械工业能耗与冶金、化工部门比较具有直接能耗低、间接能耗高等特点,下面就此问题加以粗浅地分析。一、机械工业的能耗特点 1.直接能耗低。据国外资料统计在单位产值中能源价值所占的比例:运输机械为0.85％,一般机械为0.86％,电工机械为0.60％,精密机械为0.62％。国内的情况是:制氧机行业其单位产
China’s machinery industry consumes approximately 5.5% of the country’s total energy consumption, of which the electrical energy consumption accounts for approximately 7.4% of the country’s total energy consumption. The energy consumption of the machinery industry has direct energy and metallurgical and chemical industries have relatively low direct energy consumption and indirect energy consumption. Higher features, following a shallow analysis of this issue. First, the energy consumption characteristics of the machinery industry 1. Direct energy consumption is low. According to statistics from foreign sources, the proportion of energy value in the unit output value is 0.85% for transport machinery, 0.86% for general machinery, 0.60% for electrical machinery, and 0.62% for precision machinery. The domestic situation is: Oxygen generator industry unit production
