ABSTRACT:
An electric arc plasma steam generator includes a pair of electrodes for generating the arc plasma, and a housing for enclosing the arc plasma. Jets of water are directed into the arc plasma to convert the water into steam and to ionize the hydrogen and oxygen components of the steam. Arrangements including coils and water jackets are provided for circulating water in proximity to the arc plasma and for super-heating the water contained in the water jacket and/or the coils, which are preferably mounted within the housing. An expansion chamber is connected to receive both the super-heated water, and also the superheated steam from the arc plasma, as the hydrogen and oxygen recombine to form steam once again. The arc plasma in one embodiment may be formed by electrical conduction through a spray of water containing an electrolyte; and in another embodiment electrodes may initially form the arc plasma in air or other gas, and as the electrodes are consumed, they may be advanced by a suitable mechanical arrangements including threads on the electrodes, keyway slots on the electrodes, and stepping motors which serves to advance the electrodes as needed.
