Around 75% less dust emissions when tapping liquid hot metal
At Tata Steel, we make steel from liquid hot metal. This hot metal is produces in our blast furnaces and transported to the steel plant by means of special trains. But how do we ensure that as little dust as possible is released during this process?
We take various measures to reduce dust emissions. For example, we are installing extra extraction hoods at the blast furnaces, which catch the dust as the hot metal flows out of the furnace. This reduces dust emissions by about 75%. The first hood has already been installed at Blast Furnace 7 and five more will follow this year.
We are also working on an air screen above the chute through which the hot metal passes. This air screen blows the dust to the existing extraction points, where it is suctioned away. We have already carried out tests at Blast Furnace 6 and the results are promising. This year, we will also install an air screen at Blast Furnace 7.
- 35% fewer emissions of particulate matter
- 55% fewer emissions of heavy metals
- 70% fewer emissions of lead
When opening and closing tapholes in the blast furnace, dust may escape past the filters. By placing new extraction hoods, we can remove the dust that is released during this process more precisely.
