Abstract
A flame ignition and control system includes at least one gas burner, which is connected to a gas source via a flame control system, and a safety valve controlled by a flame sensor consisting of a thermocouple. The safety valve has an open state, in which the source supplies gas to the burner, and a closed state, in which gas flow is obstructed, the switching from the open state to the closed state and vice versa being controlled by the electric signal generated by the thermocouple. An igniter device is provided, which consists of an ignition electrode and a power supply unit thereof. Furthermore, at least the operation of the igniter device is controlled according to the current strength of the electric signal generated by the thermocouple.
