Marine Fuel Oil Recovery System with Induction Heating

This paper describes fundamental characteristics of high frequency induction heating applied for Marine Fuel Oil (MFO) recovery system. The system is analyzed for an induction heating load, related to operating frequency and input power. Frequency domain characteristics of load equivalent circuit parameters in induction heating are investigated to clarify an effective circuit design of the high frequency power supply. Furthermore, the effectiveness of a high permeability ferrite gum mat on the induction heating unit to improve the heating efficiency of the induction heating system is experimented and elucidated. The practical connection method of working coils is examined. On the basis of these fundamental characteristics, MFO filled in the large scale oil tank is simulated as the sunken ship is successfully heated up by the high frequency induction method.
