ス３の２次巻線４に戻り、高圧放電閉回路を形成する。In the above configuration, the transistor 11 is QNed by a command from the combustion control circuit 2 to supply power to the high voltage transformer 3, and as a result, a high voltage is generated in the secondary winding 4 of the high voltage transformer. The generated high voltage is transferred from the spark plug 5 to the burner 6.
A spark is discharged between the burners, and if all of the multiple burners are currently receiving an ignition command, all of the multiple burners are ignited to develop combustion. The high voltage discharge current returns to the secondary winding 4 of the high voltage transformer 3 via the capacitor 7, forming a high voltage discharge closed circuit.

, and sends an ignition signal to the combustion control circuit 2. When the combustion control circuit 2 receives the ignition signal, it turns off the transistor 11 and stops supplying power to the high voltage transformer 3, completing the ignition detection operation. The combustion control circuit 2 stops the power supply to the high voltage transformer 3 when the ignition detection signals of all the burners are input, and when any burner misfires due to the influence of head wind etc. during combustion, the transistor 1 is turned on again.
