近几年来,冶金工业节约能源的工作不断深入,取得了较好成绩,积累了不少经验,现从中选出4例介绍如下。 1.鞍钢烧结总厂1979年以来,将全厂12台烧结机的点火器全部改成大点火器,使烧结工序能耗降低2～2.5公斤标煤/吨烧结矿。第三烧结厂1982年4月大点火器投产,仅半年时间就节约煤8800余吨,扣除多耗煤气,仍节约4125吨标煤。 2.上钢五厂6座燃油加热炉全部进行了节能技术改造:增加空气预热器、炉体用珍珠岩热板、炉座水管可塑料包扎,使加热炉平均吨钢油耗达到57.5公斤。其中有三座达到
In recent years, the metallurgical industry to deepen the work of energy conservation, has achieved good results, has accumulated a lot of experience, are selected from the four cases are as follows. 1. Since its establishment in 1979, Anshan Iron and Steel Co., Ltd. has changed all the ignitors of its 12 sintering machines to large ones so that its energy consumption will be reduced by 2 to 2.5 kg of standard coal per ton of sinter. The third sintering plant in April 1982 a large ignition put into operation, only half a year to save more than 8800 tons of coal, net of more consumption of gas, still save 4125 tons of standard coal. 2. On the steel plant five fuel furnace heating furnace all carried out energy-saving technological transformation: increase the air preheater, furnace with perlite hot plate, furnace hose can be plastic bandage, so that the average furnace steel fuel consumption reached 57.5 kg. Three of them arrived
