Modeling of Three Phase Electric Arc Furnaces
Abstract. In this paper are study the modeling of a three phase electric arc furnace installation. It is well know that the electric arc is a nonlinear element. Thus, for modeling his behavior, the authors are using a model which parameters like of a real electric arc. For simulation it was use the PSCAD EMTDC program. The simulations results are comparing with the measurements made of a 100t e...
متن کاملControl of Non - Ferrous Electric Arc Furnaces
An important aspect of non-ferrous metal production is the separation process known as smelting, in which the concentrated ore is melted and separated into two components of different densities: the slag and the matte. The smelting process is carried out through high-power heating in electric arc furnaces. In order to maintain a constant desired matte production rate and constant matte and slag...
متن کاملSlagging and Fouling Characteristics of HRSG for Ferrosilicon Electric Furnaces
The slagging and fouling characteristics of the heat recovery steam generator (HRSG) for ferrosilicon electric furnaces are discussed in this paper. Three ash samples were taken from the HRSG of a ferrosilicon furnace in Ningxia Province, China, which suffered from serious slagging and fouling. X-ray fluorescence (XRF), X-ray powder diffraction (XRD) and scanning electron microscope (SEM) were ...
متن کاملModeling the Electromagnetic Pollution of the Electric Arc Furnaces
The electric arc furnace is a three-phase load representing one of the most important generator of harmonic currents, reactive power and unbalanced conditions in electrical power systems. This paper aims to achieve a study concerning the power quality of the energy at 3-phase electric arc furnaces. There are analyzed the main qualitative indicators of the electric power: power factor, reactive ...
متن کاملIndicator parameters for PCDD/PCDF from electric arc furnaces
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...
