P-HGPEIi] DURAG High energy ignition The high energy ignition devices of the D-HG 400 and D-HG 500 series are suitable for the ignition of gas or liquid fuels in industrial burners of any capacity Features • Reliable ignition of gaseous fuels • Ignition of liquid fuels, up to heavy oil grade 6 • Suitable as „Ignitor Class 3 Special” in accordance with NFPA 85 • Compact set-up with integrated ignition lance • Separated set-up of ignition device and ignition lance for safe and hazardous areas • Thyristor controlled and therefore nonwearing electronic • Ignition feedback signal via potential-free relay output • LED indication at device • Integrated protection and control functionalities Applications • Chemical industry • Refineries • Cement plants • Waste incinerators • Power plants • Steam generators • Claus plants Certifications • ATEX/ lECEx • EAC Function At the high energy igniters D-HG 400 and D-HG 500 a high-voltage capacitor is discharged and a spark is created at the ignition lance's tip. The spark discharge is triggered by a non-wearing switch (thyristor). Every spark produces -depending on the model - an energy of up to 5,6 Joule at a maximum ignition frequency of 20 sparks per second. Capacity types • D-HG 400 Ignition feedback signal via LED at the device and potential-free relay output to the control room, maximum ignition energy of 90 Joule at a maximum ignition frequency of 20 sparks per second D-HG 500 Ignition feedback and status signal via LEDs at the device and potential-free relay outputs to the control room, maximum ignition energy of 112 Joule at a maximum ignition frequency of 20 sparks per second • D-HG 550 As D-HG 500 but with the additional possibility for customizing of parameters and optional available control functionalities (via software D-ESI 100 by user or DURAG-Service) ©DURAG GROUP 08/2016 • Subject to change without notice Electrical connection ER[ DURAG GmbH Kollaustrasse 105 • 22453 Hamburg • Germany
