Simply put, the Dräger Flame 5000 discriminates between a genuine fire and other radiant sources that cause  conventional detectors to produce unwanted false alarms, such as solar radiation, flare radiation, electrical arc welding, hot CO2 emissions, and black body radiation.

The Dräger Flame 5000 is a visual flame detector and a closed circuit television camera (CCTV) in one. It is engineered to combine these two technologies into the best flame detector that money can buy. It’s the safest and most advanced flame detection system available, and is proven reliable and robust, even in the harshest environment.

Superior flame detection technology is able to mask “friendly fires” without having to desensitize its fire detection capabilities. The Dräger Flame 5000 is one of the only units on the market today that has this ability.

The Anatomy of a Fire - A fire is a chemical reaction between atoms resulting in the release of heat energy. This heat energy, for the most part, is released as infrared radiation. This transfer of this energy is normally by three methods:

• Conduction
• Convection
• Radiation

During combustion, fire particles ranging in size from 0.001 to 10,000 microns are also released. Gases are also produced, the nature of which are dependent upon the combustion materials. These combustion gases generally exhibit a combination of characteristics - hot, flammable and/or toxic.

Based on the material, the flame may vary in size and color. To detect an actual fire becomes a challenge in today’s industry.

The Challenge: How to detect a fire - Many flame detectors use infrared detectors to monitor specific wave lengths characteristic of a fire. If these wave lengths are challenged, then the detector will respond indicating a fire. In practice, this is a standard way to detect a fire. However, these detectors work off the principal of infrared light source. Therefore, they’re NOT immune to false alarms from other sources of light, reflection or radiation.

The industry responded to this by producing and incorporating ultraviolet (UV) radiation detection with infrared detection to help minimize false alarms. This type of unit would respond when both the UV and IR detectors were challenged. But, the industry quickly learned that false alarms were possible due to interference from welding torches, lightening, etc. For years, both Infrared and UV / IR detectors became the standard flame detectors for many industries.

However, they were susceptible to one growing problem - false alarms. The units had no way to distinguish between black body radiation, light reflections, lightening, or welding torches. The number of false alarms continue to grow. This brought up one very practical question; “How do you safely and economically detect a fire ?”

Draeger's Answer - The Dräger Flame 5000 detector uses highly sophisticated Digital Signal Processing and Software Algorithms to process the live video image and interpret flame characteristics. These unique software algorithms are capable of discriminating between genuine fire conditions and other radiant sources that may cause conventional detectors to become desensitized or produce unwanted alarms.

Superior Design - The Flame 5000 has been designed for all types of industry. It’s heavy duty construction meets ATEX, CSA, and UL specifications making this an easy choice for the everyday warehouse or the oil rig stationed hundreds of miles offshore.

The detector’s optical self-test facility checks the window for contamination to ensure the detector’s field of view is not restricted by any obstruction.

Video images are recorded for post incident analysis and for investigation purposes, training, and to assist with future accident prevention. This surveillance system sets the Flame 5000 above the competition; it allows suitable action to take place before personnel can access the area.

Benefits of Visual Flame Detection - The Flame 5000 is designed to detect a one (1) square foot hydrocarbon fire from 144ft within a 90o cone of vision in both indoor and outdoor applications. Furthermore the Flame 5000:

• Detects radiation in the visible and near IR range
• Sensitivity IS NOT affected by water on the optics
• Not blinded by contamination from salt air, water droplets, or oil mist
• Longer detection range than conventional flame detectors

Applications

Offshore Drilling & Platforms

• Not affected by ice and water
• No sunshield or weather protector required
• Does not alarm to flare reflections from process relief flares
• Not affected by sunlight or water reflection FPSO’s
• Due to the close proximity of the process flare to the production module and decks, the Flame 5000 is immune to false alarms typical of IR based flame detectors
