Method and circuit for igniting a gas flow

Process for igniting a gas stream, characterised by the fact that by means of an electronic control unit and after activating it to ignite the gas stream

• a. a transverter is activated, which generates a higher voltage from a direct current supplied from an electricity source (10),
• b. a storage capacitor (C1) and an ignition capacitor (C2), serving to provide the ignition voltage (C2) by means of the higher voltage, are charged.
• c. an essentially familiar ignition locking magnet (6) activated by a holding current provided by the electricity source (10), while at the same time an electric circuit that exists between the ignition locking magnet (6) and a thermocouple (4) that can be influenced by the gas flame is interrupted via a relay (17).
• d. the storage capacitor (C1) is abruptly discharged via a circuit element, generating a surge of current, which briefly energises an electromagnet (5), to open an essentially familiar ignition locking valve (2) and at the same time attach anchor (3) of the ignition locking magnet (6), while the anchor (3) is held in this position after attachment because of the ignition locking magnet (6) activated by the holding current,
• e. a pilot light is generated in a familiar fashion to ignite the outflowing gas via an ignition electrode (9) connected with the ignition capacitor (C2) via an ignition transformer,
• f. further ignition procedures are initiated, whereby the ignition capacitor (C2) is re-charged, after charging a new pilot light is generated,
• g. after a prescribed period of time ignition is terminated.
• h. the holding current flowing from the electricity source (10) to the ignition locking magnet (6) is interrupted and the circuit between the ignition locking magnet (6) and the thermocouple is closed via the relay (17).
