在降低高炉燃料比的同时,回收和利用废弃的能量是高炉节能的重要方面.一、余压发电大型高炉要求更高的炉顶压力.大于3000米~3高炉的炉顶压力一般都在2.0～3.0公斤/厘米~2.现在日本、苏联、法国、美国、西德和南朝鲜的一些高炉都在安装炉顶余压发电设备.日本1981年末已有29台余压发电设备,其发电量从1974年占钢铁联合企业总耗电量的0.1%提高到1978年的1.3%,1979年上半年上升到2.6%.
In reducing the fuel ratio of blast furnace at the same time, recycling and utilization of waste energy is an important aspect of blast furnace energy conservation.First, large pressure blast furnace requires a higher pressure on the roof of more than 3000 m ~ 3 blast furnace roof pressure are generally 2.0 ~ 3.0 kg / cm ~ 2 Some of the blast furnaces in Japan, the Soviet Union, France, the United States, West Germany and South Korea are now equipped with roof-top pressure-generating equipment, of which Japan has 29 residual-voltage power generation equipment by the end of 1981, From 0.1% of the total electricity consumption of iron and steel complexes in 1974 to 1.3% in 1978, it rose to 2.6% in the first half of 1979.
