Product Description

Scope of application

• • Flame detection detection optical fibers are widely used in industrial fields that require real - time monitoring of flame status. Typical scenarios include:
  • Power industry: Flame detection for power plant boilers (coal - fired, gas - fired, and oil - fired boilers).
  • Petrochemical industry: Combustion monitoring for industrial kilns, heating furnaces, and cracking furnaces.
  • Metallurgical industry: Flame status monitoring for steel - making converters and steel - rolling heating furnaces.
  • Energy industry: Flame safety monitoring for equipment such as gas turbines and biomass boilers.

 

How it works

 

Flame detection optical fiber is a key component in flame detection systems, mainly used for monitoring the flame status of industrial combustion equipment (such as boilers, kilns, gas turbines, etc.). Its core function is to efficiently and stably transmit the flame light signals generated by combustion to the flame detector, providing the original light signal basis for the system to judge whether the flame is burning normally. The following is a detailed explanation from the aspects of structure, working principle, application scenarios and characteristics.

 

A flame detection optical fiber usually consists of the following components:

 

• Optical fiber core: As the core transmission component, it is mostly made of high - purity quartz material. It utilizes the principle of total reflection of light to achieve long - distance transmission of flame light signals.
• Cladding: It wraps around the outside of the optical fiber core, and its refractive index is lower than that of the fiber core. It ensures the stable reflective transmission of light signals within the fiber core and reduces signal loss.

 

 

 

 

• Protective layer: It is a protective structure on the outer layer, usually metal armoring (such as stainless steel) or high - temperature - resistant plastic. It is used to withstand high temperatures, vibrations, mechanical impacts, and chemical corrosion in the industrial environment, and to protect the optical fiber core and cladding from damage.
• Connector: It is an interface component at both ends and needs to be matched with devices such as flame detectors and probes (such as standard interfaces like SMA, ST). It ensures the tightness and stability of optical signal transmission.

 

Technical features

 

1. Optical signal collection: One end (probe end) of the flame detection optical fiber is installed at the observation hole of the combustion equipment, directly aligned with the flame area, to collect visible light, infrared light or ultraviolet light signals generated during flame combustion.
2. Signal transmission: The collected optical signals are transmitted to the other end (connected to the flame detector) with low loss along the inside of the optical fiber through the total reflection effect of the optical fiber core.
3. Signal processing: After receiving the optical signals transmitted by the optical fiber, the flame detector analyzes parameters such as light intensity, frequency, and flicker characteristics to determine whether the flame exists and whether the combustion is stable (such as flameout, flame deviation, etc.). It then feeds back the results to the control system to promptly trigger an alarm or adjust the combustion state (such as cutting off fuel supply, adjusting air dampers, etc.).

 

 

 

• High temperature resistance: It can work in high-temperature environments of several hundred degrees Celsius (the specific temperature resistance value depends on the material of the protective layer; metal-armored models can usually withstand temperatures above 300°C), making it suitable for the high-temperature environment of combustion equipment.
• Anti-interference: It is not affected by common interference factors in industrial environments such as electromagnetic interference and high-voltage electric fields, ensuring the accuracy of optical signal transmission.
• Flexibility: The optical fiber itself is soft and can be routed flexibly according to the installation space of the equipment, which is especially suitable for scenarios with complex structures and limited observation point positions.
• Long-distance transmission: The optical signal transmission loss is low, enabling long-distance transmission of several meters to tens of meters, which meets the monitoring needs of large industrial equipment.
• Safety: The transmission of optical signals through optical fibers avoids potential safety hazards of electrical signals in high-temperature environments and improves the safety of the system.

 

 

• During installation, ensure that the optical fiber probe is aligned with the core area of the flame to avoid being blocked by soot or water vapor, which may affect optical signal collection. Clean the optical fiber end face and probe regularly to prevent signal attenuation caused by dust accumulation and oil stains. Avoid excessive bending of the optical fiber or severe mechanical impact to prevent damage to the fiber core and impairment of transmission function. Select a model with a matching protection level (such as high-temperature resistant type, anti-corrosion type) according to the temperature, corrosiveness and other conditions of the use environment.
