ABSTRACT:
In a pilot light igniter for a burner, an inner tube for receiving fuel gas is concentrically positioned within an outer tube for receiving air in the annular space between the inner tube and the outer tube. Apertures are formed in the inner tube to impart angular momentum to the fuel gas as it flows from the inner tube into the annular space so that the mixture of air and gas swirls as it flows to the open distal end of the outer tube. A spark disk is provided on the end of the inner tube and a flame rod extends axially from the spark disk. The air and fuel mixture is ignited by a spark produced by high voltage applied between the spark disk and the outer tube. A low voltage source applied between the flame rod and the outer tube causing current pulses provides an indication of the presence of a flame.
