Abstract: Based on the theory of electromagnetic field, the Marine heavy oil electromagnetic induction heater uses the principle of electromagnetic induction to realize the energy conversion and transfer, so as to heat the heavy oil to the inlet temperature to achieve the purpose of heating.By means of electromagnetic induction, eddy currents are generated on the tubing wall under the action of a magnetic field. The wall of the heated oil pipe conducts heat energy to the heavy oil in the pipe. In this heating mode, the coil is directly around the oil supply unit pipeline of the ship for heating, and the heating effect depends on the heating electromagnetic field.Therefore, to study the electromagnetic field and its influencing factors of heavy oil electromagnetic induction heating is the premise of designing heavy oil electromagnetic induction heater.In this paper, the magnetic induction intensity generated by the electromagnetic induction heater with different pitch is analyzed theoretically, and simulated and optimized by COMSOL Multiphysics software.
