Method and apparatus for treating fluid in a conduit with radio - frequencies

摘要

Apparatus for treating a fluid in a conduit by the application thereto of radio- frequency electro-magnetic signals, comprising a core element of magnetically-permeable material extending around the conduit, and one or more primary coils through which the core element extends and energised with radio frequency electrical signals by at least one signal generator; wherein the or at least one of the primary coils has an extent and/or disposition circumferentially of the core element and conduit such as to establish an effective magnetic field throughout the core element.
