High energy ignition device

June 2014 Operator Interfaces, Switches & Relays

Durag’s D-HG 400 high energy ignition device is suitable for the ignition of gas or liquid fuels in industrial burners of any capacity. In its standard version, the ignition lance and the control unit form a compact module. Depending on the device, ignition can be triggered either through a pushbutton or automatically by feeding the supply voltage.

After fuel ignition, the ignitor tip should be retracted from the flame area as a protection against heat overload and switched off. This can be done manually or automatically, in the latter case by way of a DURAG D-VE 500 pneumatic retraction unit. With special burner types such as torch systems, no retraction is required if after ignition the flame wanders so far off that the thermal load stays within the permissible working temperature. The length of the ignition lance is manufactured to suit the furnace plant’s requirements.

Inside the ignition unit, the energy equivalent of 4,5 W is loaded into a high-voltage capacitor. With the help of a robust switching element, this energy is released to the ignition tip, where, through an arc discharge it is converted to heat. It is this arc discharge that ignites the fuel.

For ensured ignition in the start-up phase, the unit generates 20 ignition sparks during the first 60 seconds and then reduces to 5 ignition sparks/second. When the ignition device is switched to the supply voltage, the ignition function message will be issued via the built-in LED and through the ignition signal relay’s output contact. The high energy spark ignitor is also available as an explosion-proof version. Typical applications include the chemical industry, refineries, cement plants, waste incinerators and steam generators.
