Abstract
The article discusses a new type of induction installations for heating and electrophysical treatment of liquids with ionic electrical conductivity in electromagnetic fields. Methods of their calculation and optimization are proposed due to creation of local areas with large gradients of strength of electric and magnetic fields. Mathematical dependencies describing processes of phase transformation and mass transfer of scale-forming agents in gap of magnetic apparatus and in heat exchange device are derived. Calculated and experimental dependencies on effect on anti- scale efficiency of magnetic devices are determined.
