焦化工业在钢铁联合企业中的能耗比例约占8—10％。焦炭、焦炉煤气又是钢铁企业的二次能源,所以焦化工业在钢铁生产能源消费构成中占有重要地位。我国现有的焦化工业技术设备和工艺流程,大部份相当于国外五十年代水平,单位产品能耗高,重点钢铁企业的平均吨焦能耗高达220公斤标准煤,较国外先进水平高36％,且各企业间能耗差距很大。 Coking industry in the iron and steel enterprises in the proportion of energy consumption accounts for about 8-10%. Coke, coke oven gas is the secondary energy of iron and steel enterprises, so the coking industry occupies an important position in the composition of energy consumption in steel production. China’s existing coking industry technical equipment and processes, most of the equivalent of the level of foreign fifties, high energy consumption per unit of product, the key iron and steel enterprises, the average energy consumption up to 220 kilograms of tons of standard coal, 36 higher than foreign advanced level %, And the difference between the energy consumption of various enterprises is very big.
