Heating and Melting of Paraffin in a Coaxial System under the Effect of High-Frequency Electromagnetic Radiation

The impact of a microwave electromagnetic field on the melting of paraffin in a coaxial system simulating an oil well is investigated. The schematic diagram is presented of the experimental facility for the investigation of melting of paraffin in a system consisting of an internal pipe and a coaxially arranged external pipe. In the interelectrode space of these two pipes, an electromagnetic field is induced with a frequency of $2400$ MHz. It is shown that the distribution of temperature in the pipes is nonuniform, corresponding to the standing electromagnetic wave in the interelectrode space. The presence of paraffin in the interpipe space substantially accelerates the melting process in the entire coaxial system.
