D-HG 500
High energy ignition device
High energy ignition device with max. 112 J/s for direct and reliable ignition of gas and liquid fuels. The ignition frequency and duration are variable.
Functionality: Thyristor-controlled capacitor discharge, microcontroller-monitored ignition
Features
- 25% more ignition energy than the D-HG 400
- Ignition power 112 J/s
- Ignition frequency adjustable on site
- 1 … 20 sparks/s
- Modern electronic design: Microcontroller-monitored ignition, sustained short-circuit-proof, electronic protection in the event of a defective ignition tip
- Wide temperature range: -40 … +80 °C
- Relay contacts for ignition feedback and ignition readiness
- Optional retraction unit for retracting the ignition tip from the hot area
Benefits
- Reliable and safe ignition: High ignition power for direct ignition of gas and prepared oil
- Cost savings due to wear-free igniter (thyristor-controlled)
- Flexible system design: Exchangeable electronics module for compact and separate design, standardized ignition lances, ignition tips and high-voltage cables
- Certified for the applications ATEX, IECEx, Ex d IIC and Ex de IIC
Applications
- Coal-fired power plants with oil pilot burners
- Marine: Ignition of auxiliary and special boilers on ships using gas and/or oil as fuel
- Refineries: Use in potentially explosive atmospheres for ignition of gas, oil or other liquid fuels
