Abstract
An electrode arrangement for establishing a sustained electrical arc with a low voltage in which a pair of electrodes are initially brought together and then separated while a current is applied. The sustained arc is adapted to activate fuel flowing past the arc, and the flow is vortical so that the arc is caused to migrate around an annular arc gap space. Several geometric configurations of the electrodes include opposing cylindrical shapes having endwise alligned cavities and a generally tapered portions of one electrode received in a generally tapered opening in the other electrode.
