Harmonic problems are not new to electric utility and industrial power systems. In the past, most harmonicrelated problems were caused by large nonlinear loads such as arc furnaces. These types of problems have been effectively mitigated. However, due to the widespread proliferation of power electronic controlled devices nowadays, the problems caused by harmonics are of increasing importance. P...

Due to the dynamic nature of load changes, arc devices are receivers that generate disturbances network affect power quality. The main disturbance generated by these voltage fluctuations. One effects fluctuations is flicker light caused lighting receivers. article presents an analysis changes indicators measured in networks supplying furnaces. propagation lines was analyzed. parameters influenc...

Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...

ii ACKNOWLEDGMENTS I would like to thank my committee members, Professor Punam Saha and Professor Anton Kruger for their time and volunteering some of their summer to help. I would like to thank Professor Er-Wei Bai for all the direction, and always making me examine things more closely. I don't think I've ever met someone more excited about teaching. I'd like to thank Zhijun Cai for all the he...

'Rules-of-thumb', some of which were originally intended for arc furnaces, play a significant role in the design process for slag containing furnaces. Lack of fundamental understanding of the physics driving the performance of these furnaces sometimes results in either overly conservative, or poorly performing designs. This paper will explore some key technical issues related to the correct des...
