Power quality determines the fitness of electrical power to consumer devices. .Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc furnace operation. Utilities are concerned about these effects and try to take precautions to minimize them. Therefore an accurate model of an arc furnace is needed to test .In this paper a...

an electric arc furnace (eaf) is known as nonlinear and time variant load that causes power quality (pq) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. one of the most important problems to study the eaf behavior is the choice of a suitable model for this load. hence, in this paper, a probabilistic three-phase model is proposed base...

Airborne particulate matter in the silicon carbide (SiC) industry is a known health hazard. The aims of this study were to elucidate whether the particulate matter generated inside the Acheson furnace during active operation is representative of the overall particulate matter in the furnace hall, and whether the Acheson furnaces are the main sources of ultrafine particles (UFP) in primary SiC p...

Iron and steel industry is crucial for economic development. However, large exhaust volume complex feeding of the steel-making process results in enormous emissions air pollutants such as particulate matter (PM), sulfur oxides (SOx), nitrogen (NOx), polycyclic aromatic hydrocarbon (PAHs) carbon monoxide (CO). This study sampled analyzed concentrations PM, PAHs, SOx, NOx CO at inlet outlet pollu...
