Analytical Method for Magnetic Field Calculation of Induction Heater for Heat Supply Systems

Abstract

This paper presents an analysis of the need and technical feasibility of using electric heaters for heat supply systems. The use of induction heating units in the design of individual heating systems is proposed. Electromagnetic systems for the conversion of electrical energy into heat are considered. The heater is made in the form of coaxial cylinders using ferromagnetic cores. The analysis is based on magnetic equivalent circuits. The ways of optimization of the considered devices used for heating liquids in multi-purpose water heaters are formulated.
