Description
1. At-A-Glance Executive Brief
- Model: 261A1812P012
- Brand: General Electric (GE) / Industrial Combustion Systems
- Part Type: Ultraviolet (UV) Flame Detector / Sensor
- Lifecycle Status: Legacy / Plant Migration Supported
- Weight: ~4.0 kg
2. Technical Introduction
A failing optical flame detector on a heavy-duty industrial gas turbine or utility boiler trips safety interlocks, causing costly unscheduled shutdowns and lengthy purge cycles.
This ultraviolet flame sensor mounts directly to burner observation ports to monitor combustion dynamics by tracking high-frequency radiation emitted during fuel ignition and operation. Integrated into the turbine management or burner safety system, it converts optical signals into stable electronic feedback to confirm flame stability and prevent unburned fuel accumulation in the combustion chamber.
- Best Suited For: Heavy-duty gas turbine combustors, industrial power boilers, and multi-burner process furnaces.
3. Core Technical Specifications
- Manufacturer: General Electric (GE)
- Part Number: 261A1812P012
- Sensor Technology: Ultraviolet (UV) Optical Detection
- Application: Turbine and Boiler Combustion Monitoring
- Approximate Weight: 4.0 kg
- Please refer to the OEM datasheet for complete environmental tolerances.
4. Field Engineer’s Tech Notes
- Optical Lens Fouling: Combustion byproducts, soot, and oil mist rapidly coat the quartz viewing window. Establish a routine maintenance schedule to clean the lens with appropriate optical solvents; a clouded window attenuates UV radiation transfer and triggers false flame-out trips.
- Sighting Tube Alignment: Ensure the optical assembly aligns strictly with the primary combustion zone centerline. Misalignment or shifting due to thermal expansion of the turbine casing causes erratic signal strength variations under varying load conditions.
5. Adaptive QA & Testing Protocol
Each sensor undergoes rigorous optical benchmarking prior to warehouse dispatch. Testing includes regulated UV light source simulation across calibrated wavelengths to verify proper tube response and threshold switching. Signal output linearity and insulation resistance across the electrical connection pins are measured to ensure zero degradation. Detailed functional test logs and pre-shipment verification data can be provided upon request to satisfy plant safety audits.
6. Buyer’s FAQ
- What is the standard warranty coverage for this flame sensor?All units are backed by a comprehensive 12-month operational warranty from the invoice date.
