Gas Fired Igniters
Heat release max. 250 kW
- Compact design with integrated spark transformer 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 2 kW to 10 MW (7,000 BTU/hr to 35,000,000 BTU/hr)
- Custom outer tube lengths available in 10-mm increments
- Fuel types include natural gas, conditioned coke oven gas, propane/butane or process gas, according to customer preference and analysis
- Extremely tight and long pilot flame - no automatic retraction system typically required
- Class 1, 2 or 3 gas fired igniters according to NFPA also available
- Also available with flexible outer tube for tilting burners
Applications
- Ignition of large gas, oil or heavy fuel oil burners in utility boilers
