High Energy Spark Ignitor D-HG 400 The Durag High Spark Igniter ignites oil and gas burners of any capacity, In its standard version, the ignition lance and the control unit form a compact module. Depending on the ignition device model, ignition can be triggered either through a push button or automatically by feeding the supply voltage. After fuel ignition, the igniter tip must be retracted from the flame area as a protection against heat overload.

The Durag High Spark Igniter ignites oil and gas burners of any capacity, In its standard version, the ignition lance and the control unit form a compact module.
Depending on the ignition device model, ignition can be triggered either through a push button or automatically by feeding the supply voltage.
After fuel ignition, the igniter tip must be retracted from the fl ame area as a protection against heat overload. This can be done manually or automatically, (automatically by way of a Durag D-VE 500 Pneumatic Retraction Unit. With special burner types (e.g. torch systems), no retraction is required if after ignition the fl ame wanders off so far that the thermal load stays within the permissible working temperature.
The length of the ignition lance is manufactured to suit the furnance plants requirements.
Inside the ignition unit, the energy equivalent of 4.5 Ws is loaded into a high-voltage capaciter. With the help of a wear-proof switching element, this energy is released to the ignition tip, where through an arc discharge is converted to heat. It is this arc discharge that ignites the fuel.
