Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

A novel method to mitigate voltage flicker problem usually caused by DC Arc Furnaces has been presented in this paper. This method called Direct Current Ripple Re-injection is applied to a multi-step switching reactor in the output of the AC/DC converter to make the output load current as smoother as possible. This method would lessen harmonic effects properly. The proposed approach is simulate...

This paper presents guidelines for the accurate evaluation of harmonics and flicker generated by ac electric arc furnaces, and its propagation through transmission and distribution systems. It is presented a typical case where a HV system supplies a high capacity arc furnace. The electrical network is simulated using the ATP version of the EMTP where a non-linear time-varying three-phase arc mo...

Accurate modelling of the Electric arc furnace (EAF) is necessary to study its impact on power systems. Here, a new model for EAF presented in which both non-linearity and time-varying characteristics are taken into account. The consists seven parallel current sources represent fundamental harmonic currents. Magnitude phase magnitude second seventh harmonics considered as updated every 0.01 s. ...

The unintentional formation and release of persistent organic pollutants (POP) from industrial sources is of environmental concern and efforts are now made to reduce these emissions [1]. The emissions of chlorinated trace organics from electric arc furnaces (EAF) have been monitored on a regular basis in Sweden since the 1980s. Most analyses have encompassed not only polychlorinated dibenzo-p-d...
