Dioxins in Cupolas, Rotary and Electric Arc furnaces: Emission free melting practices in Foundries

Abstract

The emission limit value of the

Incineration Directive is being

assumed more and more by other

industrial sectors. Following this and

despite the BREF document

developed by the EIPPCB does not

establish a limit as an obligation to

fulfil, European foundries have

decided to tackle this problem which

is becoming a common problem for

many of them. In the first place, it

has been determined the current

situation in terms of dioxin emission

in cupolas, rotary and electric arc

furnaces as more probable

equipments producing dioxins in the

melting process of steel or cast iron.

The scope includes not only

determining the current situation

(up streams) but implementing

feasible and suitable capture

systems (down streams). All these

solutions customized for every

studied furnaces.
