CFD Modelling of Industrial Plant from a Viewpoint of Dioxins Formation
Design procedures of thermal industrial plant should take into account all aspects governing future plant emissions, in order to devise in due course all necessary primary (preventive) as well as secondary (curative) measures. For dioxin-sensitive operations, such as incineration and thermal metallurgical processes, the specific characteristics of dioxin formation and destruction should be carefully considered from the start. This means that different dioxin-relevant plant operating parameters, such as gas and particle flow, field of temperature, oxygen concentration and dust content of the off-gases, the residence times of entrained particles and – as far as possible - their contribution to dioxin formation should be established. The possibilities and limitations of the method are highlighted and a number of possible primary and secondary measures are presented. The best method of establishing the data required is based on Computer Fluid Dynamics (CFD) studies, which should be an intrinsic part of plant design. This CFD-analysis may proceed, e.g., by means of the FLUENT programme, which was initially co-developed by one of the authors (J.S.) and thoroughly tested for dioxin applications during the MINIDIP programme.
