Main Features of a Modern High Capacity Blast Furnace
Sep 20 2019 · Modern high capacity BFs operate with high blast temperature and low blast humidity by adjusting the amount of PCI to control the furnace temperature. In many furnaces the blast temperature is stabilized at 1 230 deg C to 1 250 deg C and the moisture in blast is stabilized at 10 g/N cum to 15 g/N cum.

Blast furnaces have grown considerably in size during the twentieth century. In the early days of the twentieth century blast furnaces had a hearth diameter of 4–5 m and were producing around 100 000 THM per year mostly from lump ore and coke. At the end of the twentieth century the biggest blast furnaces had between 14 and 15 m in hearth diameter and were producing 3–4 million tons of
