Claims

[Scope of utility model registration request]

A first memory that is set by detecting that the shutoff means is normal when a start signal is given, and a pre-purge that is started in response to the output when this first memory is set. A prepurge shift register that measures a period and outputs a prepurge end signal at the end of the prepurge period, a second memory that is set in response to the prepurge end signal, and a state in which the second memory is set. A drive circuit that operates to ignite the pilot burner upon receiving the output signal, and a drive circuit that is activated upon receiving the pre-purge end signal to measure a predetermined ignition trial period, and generates an ignition trial end signal at the end of this ignition trial period. and a third memory that is set in response to a flame detection signal indicating ignition of the pilot burner or the trial end signal and outputs a signal for igniting the main burner, The drive circuit is charged with a transistor that is driven by a pulse signal of a predetermined frequency when the second memory is set, and a current that is supplied through the first diode when the transistor is off. A first capacitor is connected via a second diode between the first capacitor and the emitter side of the transistor, and when the transistor is turned on, a second diode is connected between the first capacitor and the emitter side of the transistor. A relay energized by a discharge current flowing through a diode and a second relay connected in parallel with this relay.
A digital combustion control device characterized by comprising a capacitor and a capacitor.
