Example of current emisions from some dust abatement applications

In melting processes, dioxins may be produced if the conditions that give rise to sueh pollutants are present at the same loeation and time in the process. These conditions are  

In evaluating the risk of dioxin formation, a distinction can be made between non-ferrous and ferrous foimdries  

Ferrous foundries Depending on the furnace type and metal load the conditions for dioxin formation could occur. Considering the high temperatures in the melting furnace, dioxin emission (if occurring at all) will mainly generate from de-novo s mthesis. The above-mentioned conditions can be used to evaluate the risk of dioxin formation.
