一、钢铁能耗与污染态势钢铁行业既是能量消耗的大户，又是污染大户。１９９６年我国的钢产量为９６０２万吨，生铁产量为８９７７万吨，吨钢能耗平均为１．３９２吨标准煤。因为钢铁生产的主要能源为化石类低效能源，转化过程中会释放大量的二氧化硫、氮氧化物、温室气体（二
First, steel energy consumption and pollution situation The steel industry is not only a big energy consumption, but also a big polluter. In 1996, China’s steel output was 96.02 million tons and its pig iron production was 89.77 million tons. The average energy consumption per ton of steel was 1.392 tons of standard coal. Because the main source of energy for steel production is inefficient fossil energy sources, a large amount of sulfur dioxide, nitrogen oxides, greenhouse gases (di
