Device for the inductive flow-heating of an electrically conductive, pumpable medium

摘要

Device for the inductive flow-heating of an electrically conductive pumpable medium, whereby there are provided in the device pipeline windings, through which the medium flows, on a magnetic yoke in which with the aid of an inductive alternating current energy transfer in accordance with the transformer principle electric voltages are induced. At least two such pipeline windings are connected with each other via supply distributor and mixer pieces in such a way that a short-circuit current flows in a closed path of the medium in the pipeline windings, fed by the induced voltages, which heats the medium. A further development provides that there are provided heating elements connected with the pipeline windings and adapted in dimensions to these windings, in which heating elements a rapid local heating can be obtained through current density concentration.
