Abstract To study the electric furnace melting process of different process parameters (e.g., current frequency, electric current intensity, the insertion depth of the electrode column, and water wall temperature) for each field quantity change and the impact of electric furnace slag conditioning, the mathematical model of the electromagnetic and temperature fields of the slag tempering process in electric furnace was established, and the numerical simulation was analyzed by the ANSYS finite element software. Research results show that current skin effect appears with the increase in current frequency, while the difference between the two ends and the center of the magnetic induction… More >

Abstract In the era of serious greenhouse gas emission and energy shortage, it is necessary to use solid waste to prepare new renewable materials. In this work, the potential application of reed straw and electric furnace dust was explored. Firstly, magnetic carbon carrier (EFD&C) was prepared by high temperature calcination, and then magnetic carbon catalyst (SM@EFD&C) was prepared by activation of sodium methoxide. The catalyst was used to prepare biodiesel by transesterification reaction to test its activity and stability. Reed biochar, EFD&C and SM@EFD&C were detected by Diffraction of X-rays (XRD), Fourier transform infrared (FT-IR), Inductively coupled plasma (ICP), Scanning electron… More > Graphic Abstract

Abstract With the significant progress of the “coal to electricity” project, the electric kiln equipment began to be connected to the distribution network on a large scale, which caused power quality problems such as low voltage, high harmonic distortion rate, and high reactive power loss. This paper proposes a two-stage power grid comprehensive resource optimization configuration model. A multi-objective optimization solution based on the joint simulation platform of Matlab and OpenDSS is developed. The solution aims to control harmonics and optimize reactive power. In the first stage, a multi-objective optimization model is established to minimize the active network loss, voltage deviation,… More >
