Oil Fired Igniters
Heat release max. 2800 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
