The principle of electromagnetic steam generator is the use of electromagnetic induction heating, through the frequency converter power supply (electromagnetic heater) will be rectified AC inverter into DC and then DC into high-frequency alternating current, high-frequency alternating current role of the heating furnace outside the coil to produce alternating magnetic field, magnetic lines of force cutting the coil heating the furnace body to produce eddy current, through the collision of eddy currents to make the body of the furnace rapid heating, so as to achieve the purpose of heating the furnace body of water, water The water is heated to more than 100 degrees and vaporized to produce steam.
