Product Specifications

Technical details and manufacturing context for Flame Scanner / Detector

Definition
A critical safety component within burner systems that continuously monitors flame status using optical or thermal sensors, ensuring safe operation by detecting flame presence, absence, or instability to prevent unburned fuel accumulation and potential explosions.
Working Principle
Operates by detecting specific wavelengths of light (typically ultraviolet or infrared) emitted by flames, or by sensing flame temperature through thermocouples or thermopiles, converting these signals into electrical outputs that indicate flame status to the burner control system.
Common Materials
Stainless steel housing, Quartz glass lens, Photodiode/UV sensor, Electronic circuitry
Technical Parameters
  • Spectral response range (typically 180-260nm for UV, 700-1100nm for IR) (nm) Per Request
Components / BOM
  • Optical Lens
    Focuses flame radiation onto the sensor element
    Material: Quartz glass
  • Sensor Element
    Converts flame radiation into electrical signals
    Material: UV/IR photodiode or thermopile
  • Signal Processor
    Amplifies and conditions sensor signals for output
    Material: Electronic components on PCB
  • Housing
    Protects internal components from environmental conditions
    Material: Stainless steel
Engineering Reasoning
0.5-5.0 m detection distance, 190-650 nm spectral response, -40°C to +85°C ambient temperature
Flame signal intensity drops below 1.0 μA at 2.0 m distance, UV sensor quantum efficiency falls below 15% at 300 nm, lens contamination reduces transmission below 70% at 400 nm
Design Rationale: UV photocathode poisoning from hydrocarbon deposition reduces photoelectric emission, quartz lens devitrification from prolonged >500°C exposure creates crystalline SiO₂ scattering centers, electromagnetic interference above 10 V/m at 50-500 MHz disrupts photomultiplier tube gain stability
Risk Mitigation (FMEA)
Trigger Silicone vapor deposition from gasket outgassing at 150°C
Mode: UV sensor quantum efficiency degradation from 25% to 8% over 2000 hours
Strategy: Install activated carbon breather filter with 0.3 μm particulate rating on enclosure ventilation
Trigger Thermal cycling between -30°C and +80°C at 5 cycles/hour
Mode: Fiber optic bundle fracture at epoxy-glass interface due to 0.02% CTE mismatch
Strategy: Replace epoxy with silicone gel encapsulation having 300% elongation at break

Cause: Thermal stress or aging of infrared/ultraviolet sensors, leading to reduced sensitivity or false readings from prolonged high-temperature operation.
Maintenance Indicators
  • Intermittent or false flame failure alarms during stable combustion conditions
  • Visible soot buildup or discoloration on the scanner lens or housing
Engineering Tips
  • Implement regular lens cleaning schedules using approved solvents and soft materials to prevent permanent contamination damage
  • Install protective air purge systems to maintain positive pressure and keep contaminants away from optical components
