Abstract
An electromagnetic induction steam generator is compact or ultra-compact and highly efficient, and capable of continuous operation, intermittent operation and empty-heating operation. Magnetic flux passes through a closed magnetic circuit of two leg iron cores, a heater, and a yoke iron core after a low-frequency alternating current is supplied from a power supply to electric wire coils. Joule heat is generated inside the heater by the permeation of magnetic flux. When fluid such as water, is supplied from the fluid supply port, it is heated and becomes steam within the heating chamber. The steam then emerges from the steam output port.
Claims9
An electromagnetic induction steam generator comprising:
- at least two leg iron cores wrapped by electric wires to form a coil around each core, said coil receiving a low-frequency alternating current from a power supply connected to said electric wires;
- and a closed magnetic circuit directly connecting the inner side of each said leg iron core, at least one part of said closed magnetic circuit being a heater made of a metallic material to permit flux permeation and to resist corrosion which can be heated by Joule heat,
- wherein said heater has a fluid supply port and a steam output port, and said heater has a hollow chamber in its central portion and uses a gas-liquid separator, wherein said heater is capable of producing steam from fluid supplied to said hollow chamber through said fluid supply port.
