Abstract
Induction type heat generators are widely used in technologies for drying materials of natural and artificial origin. This allows using non-contact action on the heat carrier, unlike traditional heat generators, where air heated by the products of combustion of mineral fuel acts as a drying agent, to exclude the impact of carcinogens on the final product, to ensure fire safety in the absence of an open flame, does not pollute the environment with combustion products in due to their absence. Despite the fairly wide industrial implementation of these technologies, the issue of creating new and improving known induction heating systems for drying technologies of natural and artificial origin remains relevant, and their design methods require further development and generalization. The purpose of this work is to develop, using the method of secondary sources, a mathematical model for the analysis of the three-dimensional magnetic field in a three-phase heat generator of the induction type, taking into account the symmetry of its geometry, powered by a three-phase voltage source. On the basis of the method of secondary sources, a three-dimensional mathematical model of an induction-type heat generator was developed when it is powered by a three-phase voltage source with a load in the form of unbonded ferromagnetic conductive tubes/rods, taking into account the symmetry of the density distribution of secondary sources of the electromagnetic field, which allows rational use of computing resources, conducting analysis influence of the geometrical, electrophysical, mode parameters of the induction type heat generator on heat losses in the loaded, which are heat sources for heating the coolant.
