Blast Furnace and its Design

The ratio of total furnace height to belly diameter for mid and large size blast furnaces decreases from around 3 to 2.00 as the furnace useful volume increases from 1000 cum to 5500 cum. The ratio of furnace belly diameter to furnace hearth diameter varies in the range of 1.09 to 1.13 ( ideally it should be 1.05 to 1.10) .
