Oil Fired Igniters

Heat release max. 3600 kW

  • Compact design with integrated ignition module and ionisation flame monitor/burner control
  • Built-in flame rod, ideally located
  • No high-voltage cable required on site
  • Guaranteed electromagnetic compatibility
  • Rugged, low-maintenance design
  • Sizes ranging from 300 kW to 3.6 MW (1,000,000 BTU/hr to 12,000,000 BTU/hr)
  • Custom outer tube lengths available in 10-mm increments
  • For extra light fuel oil (diesel), dual fuel igniters can also handle either propane/butane or natural gas
  • Extremely tight and long pilot flame - no automatic retraction system typically required
  • Class 1, 2 or 3 oil fired igniters according to NFPA also available
  • Smoke free flame
  • Also available for marine diesel operation

Applications

  • Ignition of large coal or heavy fuel oil fired burners in utility boilers
