Design of Powerfull Electromagnets for Separation of Steel Parts from Coal on Conveyor Belts for Coal Delivery at Thermal Power Plants

Goal: In this project the focus is placed to the dimensioning and verification of the design of a powerful (5-22 kW) electromagnets powered from a 110 or 220 V DC source. The application of the designed electromagnet refers to systems for electromagnetic separation of medium and large steel parts that may be found in the coal that is transported on the conveyor belts for the delivery of coal to thermal power plants. The application of the electromagnetic separator is directly related to the system for detecting the presence of metal steel parts (metal detector). In the case of inefficient operation of the system for separation of steel parts from coal, severe accidents can occur in the system for grinding and crushing coal at thermal power plants. The design of the electromagnet presented in this paper was verified in the software package FEMM 4.2.
One of the goals of this project is the design of the power converter (AC/DC) which achieves continuous regulation the excitation force of the powerfull electromagnet.

The paper presents dimensioning and verification of the design of a powerful 22 kW electromagnet powered from a 220 V DC source. The application of the designed electromagnet refers to systems for electromagnetic separation of medium and large steel parts that may be found in the coal that is transported on the conveyor belts for the delivery of coal to thermal power plants. The application of the electromagnetic separator is directly related to the system for detecting the presence of metal steel parts (metal detector). In the case of inefficient operation of the system for separation of steel parts from coal, severe accidents can occur in the system for grinding and crushing coal at thermal power plants. The design of the electromagnet presented in this paper was verified in the software package FEMM 4.2. The model is defined as a 2D planar magnetostatic model. At the end of the paper, the final simulation results of this project are presented.
