Optimization and research of coil based on marine heavy oil electromagnetic heater

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