Oil burner spark ignition system
Abstract
Abstract AN OIL BURNER IGNITION SYSTEM PRODUCES A TONGUE-LIKE CONFIGURATION OF INDIVIDUAL SPARKS EXTENDING FROM A PAIR OF DISCHARGE ELECTRODES AND INTO THE SPRAY PATTERN OF OIL PARTICLES PRODUCED BY THE BURNER NOZZLE. THE SYSTEM INCLUDES A SPARK GENERATING RELAXATION OSCILLATOR CIRCUIT CAPABLE OF PRODUCING INDIVIDUAL SPARKS AT A FREQUENCY SUCH THAT SUBSEQUENT SPARKS ARE ABLE TO FOLLOW THE ELONGATING IONIZED AIR PATH ESTABLISHED BY PREVIOUS SPARKS. THE OSCILLATOR CIRCUIT INCLUDES A CAPACITOR CHARGED FROM AN AC POWER SOURCE AND REPTITIVELY DISCHARGED DURING ALTERNATE HALF CYCLES AT RAPID INTERVALS THROUGH THE PRIMARY WINDING OF A TRANSFORMER BY MEANS OF A CONTROLLED RECTIFIER GATED IN ACCORDANCE WITH THE CAPACITOR CHARGE LEVEL.
