  • Automatic flame-out detector and reignition system and method of ignition
    Patent number: 6729873
    Abstract: An automatic flame-out detector and reignition system for a fuel burning apparatus comprises at least one spark generator. The spark generator comprises a spark gap and a transformer. The transformer has a primary winding and a secondary winding. The spark gap is connected across the secondary winding of the transformer. A switch is in electrical communication with the primary winding such that when the switch is in a first state, electrical current may flow through the primary winding and when the switch is in a second state, electrical current may not flow through the primary winding. The system comprises at least one flame detector having an output indicating the presence of a flame. A programmable circuit having an input for receiving the output of the flame detector and an output for triggering the spark generator is provided. A method of ignition is also provided.
