DURAG SPARK IGNITION SYSTEMS

DURAG electronic igniters ignite oil and gas burners of any capacity in industrial applications and power plants.

The energy required for ignition of the burner is stored in a high-voltage capacitor in the device. The energy is then switched to the igniter tip via a wear-resistant electronic switch. The resulting spark discharge at the igniter tip will ignite the fuel. For reliable ignition during the start phase, the igniter delivers 20 sparks/s for 60 seconds and then switches down to 5 sparks/s (D-HG 400). When the operating voltage is switched on, the igniter will automatically begin to spark. The ignition function of the igniter is signaled via an LED and the potential-free contacts of the igniter acknowledgment relay.

The ideal position of the igniter tip for igniting oil burners is generally at the edge of the atomizing cone directly in front of the swirler. The actual position is determined by adjusting the igniter tip axially by hand. If heavy oil is being fired, it is necessary to sufficiently preheat it to between 90°C and 130°C. In the case of gas burners, the position of the igniter tip is not of critical importance. There must, however, be a mixture of fuel and air present at this position. For a soft start, a low flow velocity (start-up position of the burner) should be set.
