Burner Combustion Safety Solution – Alstom DFI-100-340F | Diagnostic Flame Indicator Series
Where This Product Is Used
The Alstom DFI-100-340F Diagnostic Flame Indicator is engineered for continuous flame monitoring in demanding industrial combustion environments. Typical deployment sites include:
- Coal-fired & gas-fired power generation plants — burner management systems (BMS) requiring per-burner flame proof
- Industrial boilers — package boilers and utility boilers where flame loss detection is safety-critical
- Petrochemical & refinery process heaters — fired heaters, reformers, and cracking furnaces
- Cement & lime kilns — rotary kiln burner flame supervision
- Waste-to-energy (WtE) facilities — multi-burner grate systems requiring individual flame status
- Marine & offshore boiler systems — where compact, diagnostics-capable detectors are mandated

Why Engineers Specify This Model
- UV-specific 340 nm detection — discriminates true combustion flame from background infrared radiation, reducing nuisance trips in high-temperature furnace environments
- Integrated diagnostics — the DFI-100 series provides self-check and signal-strength readout, enabling predictive maintenance before detector degradation causes unplanned shutdowns
- Drop-in replacement — compatible with existing Alstom/GEC burner management panel wiring, minimizing retrofit engineering hours
- Compact form factor — 350 g unit fits tight scanner port arrangements on multi-burner boiler fronts
- Proven field reliability — widely specified in European and Asian power utility BMS upgrades and OEM panel builds
Complete System Bill of Materials
For a complete burner flame monitoring loop, engineers typically pair the DFI-100-340F with:
- Sight tube / purge air assembly (matched to burner throat diameter)
- Alstom BMS controller / flame amplifier card (DFI series compatible)
- 24 V DC regulated power supply (DIN-rail mount)
- Shielded signal cable (twisted pair, ≥0.5 mm²)
- Terminal block / marshalling panel for multi-burner arrays
- Spare detector unit (recommended 1:10 ratio for critical boiler applications)

Application-Specific FAQ
Q: Is the DFI-100-340F suitable for oil-fired burners?
A: Yes. UV detectors at 340 nm respond to the UV emission from both gas and oil flames. Confirm sight tube alignment and purge air flow rate for heavy fuel oil applications.
Q: Can this unit replace an older Alstom/GEC flame scanner directly?
A: In most cases yes — the DFI-100 series was designed as a form-fit-function upgrade for legacy GEC Alsthom BMS panels. Verify connector pinout against your panel drawing before installation.
Q: What is the recommended replacement interval?
A: Alstom recommends periodic sensitivity checks every 12 months. The integrated diagnostic output allows condition-based replacement rather than fixed-interval swap-out.
Q: Do you provide installation support?
A: We provide technical documentation and remote commissioning guidance. On-site support can be arranged through our partner network — contact us for details.
Q: Is export to my country permitted?
A: The DFI-100-340F is a standard industrial instrument with no ITAR/EAR restrictions. We ship globally. Import duties and local compliance are the buyer’s responsibility.
