D-HG 400
High energy ignition device
High energy ignition device with 90 J/s for direct and reliable ignition of gas and liquid fuels.
Functionality: Thyristor-controlled capacitor discharge, microcontroller-monitored ignition
Features
- Technology and design proven over more than 30 years
- Ignition power 90 J/s
- Microcontroller-monitored ignition
- Sustained short circuit-proof and electronic protection in the event of a defective ignition tip
- Relay contact for ignition feedback
- 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 and 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: Reliable direct ignition with well-prepared oil (steam-atomized)
- 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
