METHOD AND DEVICE FOR INDUCTION HEATING OF LIQUIDS (VERSIONS) Russian patent published in 2012 - IPC H05B6/06 

FIELD: electricity.

SUBSTANCE: in the proposed method and the device for heating of a reservoir with liquid that realises it a resonant self-oscillating mode of high-frequency electromagnetic mode f₀=1-100 kHz is developed in the inductance winding of the heater, and the material of heated reservoir and liquid is exposed to the produced electromagnetic field in the field of frequencies of maximum losses in the reservoir material, at the same time the temperature of heated liquid is measured at the output from the reservoir, it is compared to the specified value, and accordingly the heated liquid temperature is maintained within the specified parameters. In another version of the method and device the electromagnet energy is transmitted from the converter to the inductance winding with the help of a high-frequency resonant transformer along a single-wire waveguide line.

EFFECT: reduced losses of energy during heating of liquids, reduced losses in supply wires, higher efficiency factor and effectiveness of liquids heating.
