Title (EN) SOIL HEATING WITH A ROTATING ELECTROMAGNETIC FIELD
(FR) CHAUFFAGE D'UN SOL AU MOYEN D'UN CHAMP ELECTROMAGNETIQUE TOURNANT
Abstract:
(EN) A soil remediation system heats contaminated soil (34) by generating a rotating sub-surface electromagnetic field. The system includes three electrodes (12, 16, 24) disposed 120 degrees apart on a remediation circle. These electrodes (12, 16, 24) are excited by AC voltages with 120 degree phase differences relative to each other. This results in the generation of a sub-surface travelling wave that propagates in a circumferential direction.
(FR) Selon l'invention, un système de rénovation d'un sol s'effectue par chauffage du sol contaminé (34) au moyen d'un champ magnétique tournant généré sous la surface. Le système comprend trois électrodes (12, 16, 24) disposées à 120 degrés sur un cercle de rénovation. Ces électrodes (12, 16, 24) sont excitées à l'aide de tensions alternatives présentant un décalage de phase de 120 degrés entre elles, ce qui produit, sous la surface, une onde mouvante qui se propage dans une direction circonférentielle.
