Act, 2005: NO
Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by using energy stored in a capacitor at a breakdown for creating an
ignition arc at the electrodes of a resistive arc probe, having a semiconductor resistive film across spark electrodes of the resistive arc
probe, designed to preclude interference of contaminants with conduction of an ignition arc across an established current path between
the electrodes of the resistive arc probe. An air gap and a resistive arc probe are connected in series. A first high voltage power supply
develops a first direct current voltage across a capacitor, which is supplied as a voltage across the air gap and the resistive arc probe. A
second high voltage power supply supplies a second pulsed voltage across the air gap and the resistive arc probe, wherein the second
pulsed voltage is substantially higher than the first direct current voltage, aid the second pulsed voltage jumps the gap of the air gap and
thus initiates and ignition arc probe.
