<p>A steam generating apparatus includes a chamber defining structure for defining a heating chamber for heating a fluid medium such as liquid and/or air; an exciting coil mounted on the chamber defining structure so as to surround the heating chamber and operable, when electrically energized by application of an alternating current power thereto, to produce an alternating magnetic field; a porous heating element disposed within the heating chamber, said porous heating element having a high porosity and adapted to be heated by an induction current developed by the alternating magnetic field produced by the exciting coil; and a liquid supply system for supplying a liquid medium to the heating chamber to allow the liquid medium to be heated in contact with the porous heating element to thereby produce steam.</p> |
