Flame Detection
Fire Detection

A flame detector is a sensor designed to detect and react to the presence of a flame. These sensors possess the capability to distinguish both smokeless liquids and smoke associated with open fires. These detectors can sense fire based on air temperature and movement. Utilizing Ultraviolet (UV) or Infra-Red (IR) technology, they swiftly identify flames, enabling near-instantaneous alerts

How does Flame Detection Work?

Flame detectors look for the specific frequencies of UV (Ultra Violet) and/or IR (Infra-Red) radiation to detect a flaming fire.

The radiation produced by flames fall within a unique range of frequencies/wavelengths – the detectors only operate within these ranges to help eliminate the risk of false alarms.

Types of Flame Detectors

There are four different types of flame detectors, including:

  • Ultraviolet (UV) Flame Detectors: These detectors work by sensing the ultraviolet radiation emitted by flames. They are effective in detecting flames that emit UV radiation, such as those from hydrocarbon fires.
  • Infrared (IR) Flame Detectors: IR flame detectors operate by sensing the infrared radiation emitted by flames. They are useful for detecting fires that produce significant amounts of infrared radiation, such as those fueled by hydrocarbons, but they may have limitations in detecting certain types of flames, like those from hydrogen fires.
  • UV/IR Flame Detectors: UV/IR flame detectors have sensors for ultraviolet (UV) and infrared (IR) radiation, which work separately. They use extra circuitry and wiring to handle both signals, reducing false alarms.
  • These detectors work well indoors and outdoors because they’re less likely to give false alarms. But they can only detect fires that give off both UV and IR radiation.Top of Form
  • Visual Light Flame Detectors: Visual flame imaging detectors use CCD image sensors to spot fires. They analyze live video from these sensors to figure out the shapes and growth of possible fire sources. This helps them tell if there’s a real fire hazard or not.
  • One good thing about these detectors is they don’t need carbon dioxide or other combustion products to find fires. But they can’t detect fires that the human eye can’t see, like hydrogen flames.

Flame Detection System Application

  • Waste recycling
  • Manufacturing plants
  • Power plants
  • Turbine rooms
  • Chemical production plants
  • Industrial warehouses

Flame Detectors important key points

  • UV-only detectors are prone to false activations. They are best suited to dark/enclosed areas.
  • IR2 or IR3 detectors are more versatile and more resistant to false alarms than UV detectors. They are also able to remain effective in high levels of obscuration.
  • UV/IR3 Flame detectors are very reliable in outdoor areas, or areas with a lot of natural light shining in.
  • A flame detector contains multiple sensors (e.g., a UV/IR2 has one UV sensor and two IR sensors).  All of these sensors must recognize the fire condition simultaneously to activate the detector.

Flame Detectors in Waste Recycling Fire Protection

  • Flame Detection is a reliable and cost-effective solution for protecting open risk areas at waste recycling facilities. They are commonly used for activating automatic fire suppression systems.
  • Flame Detection is not always suitable for the protection of waste recycling process lines. The speed that the material moves at through these areas means that the detector could be unable to spot the fire before it has passed – going on to cause more damage further down the line. Ember/Transit detectors are best for process areas.
  • We typically recommend IR3 Flame detectors for waste recycling applications. IR3 detectors offer very speedy (although very accurate) fire detection, and will not be accidentally triggered by activities such as arc welding and flashing lights etc.
  • However, if there is a lot of natural light entering the building, IR3 Flame detectors could be prone to false alarms. In this case, we would use UV/IR2 Flame Detectors which are resistant to sunlight.
