Comment choisir les bons appareils pour surveiller le risque d’incendie.
Les flammes émettent des rayonnements électromagnétiques dans les longueurs d’ondes infrarouges (IR), la lumière visible et les longueurs d’ondes ultraviolettes (UV), en fonction de la source de combustible. Certaines flammes étant invisibles à l’œil humain, les détecteurs de flamme actuels utilisent des technologies optiques pour remplir leur fonction de détection. Des technologies optiques de détection de flamme ont été mises au point et utilisent les UV, les UV/IR et les infrarouges multispectres pour détecter les flammes de différentes sources de combustibles. Ces produits de détection de flamme s’appuient sur la portée optique du rayonnement émis dans les bandes spectrales pour déterminer s’il s’agit véritablement d’une flamme.
Déterminez si la flamme potentielle que vous cherchez à détecter sera à base d'hydrocarbure ou non organique. Avec des flammes d'hydrocarbures, une combinaison de méthane et d'oxygène produit du dioxyde de carbone et de l'eau. Ce type de feu crée un signal UV à une longueur d'onde de 0,2 micron et un signal IR à 2,7 microns et 4,5 microns. Les flammes d'hydrogène ne produisent que des molécules d'eau, de sorte que nous ne pouvons pas observer le même pic de CO2 qu'une flamme d'hydrocarbure est censée produire.
Les conditions ambiantes telles que la lumière du soleil, la foudre, les objets chauds et d'autres sources non inflammables peuvent provoquer de fausses alertes. Il est essentiel que le détecteur de flamme soit capable de faire la distinction entre un incendie réel et une fausse source de rayonnement.
Les technologies de détection de flamme sont efficaces pour reconnaître une flamme à différentes distances. Il est important d'utiliser un détecteur qui puisse fonctionner à l'intérieur de la plage de détection requise.
Les détecteurs optiques de flamme sont équipés d'un champ de vision similaire à celui de l'objectif d'une caméra. La prise en compte du champ de vision permet de déterminer le nombre de détecteurs nécessaires pour couvrir une installation ou une zone spécifique de l'installation.
Optical Flame Detection for the Process Industry
There's no such thing as "too safe" when operating storage tank farms, especially when these tank farms are located near urban areas. Next generation Rosemount 975 Flame Detectors help detect fires in tank farms to keep your operation running smoothly and safely. A full fire prevention solution helps ensure more uptime, extended asset life and minimized operating costs. Avoid devastating results of personnel injuries and equipment damage.
Oil wells have the potential to create flammable vapors and gases, increasing the risk of fire or explosions which can occur without warning. Next generation Rosemount 975 Flame Detectors provide continuous flame detection even in extreme temperatures and harsh winds to keep personnel and equipment safe.
Various hazards are associated with loading and unloading flammable and toxic products, including accidental release and potential of ignition. Next generation Rosemount 975 Flame Detectors continuously provide ultra-fast flame detection response speeds - as low as 20 ms – to help protect personnel and equipment
Due to the constant high stress on compressor machinery and potential for fires, compressor stations require continuous flame monitoring. Next generation Rosemount 975 Flame Detectors detect fires with ultra-fast response speeds as low as 20 milliseconds.
Aircraft hangars come with unique challenges as highly combustible aviation fuel leaks can occur. Next generation Rosemount 975 Flame Detectors help protect personnel and costly equipment, by detecting fuel and gas fires at long distances and over wide areas. Flame detectors are installed at the structure's corner and at ground level to help ensure the detectors' field of view covers any area where fire may occur.
Food and beverage processing and storage facilities present unique safety risks. Next generation Rosemount 975 Flame Detectors protect personnel and equipment, detecting fires with a high immunity to false alarms. With a durable stainless steel body and heated optics to eliminate condensation and icing, operating temperatures range from -76 °F to +185 °F (-60 °C to +85 °C) and cover areas up to 300 ft. (90 m).
Fire is a constant possibility at waste management sites as many types of waste are readily combustible. Next generation Rosemount 975 Flame Detectors continuously monitor and quickly detect fires, while protecting personnel and equipment. Rosemount 975 Flame Detectors detect fires at long distances and over wide areas with a high immunity to false alarms and ultra-fast response speeds - as low as 20 milliseconds. Flame detectors are strategically installed in multiple locations, ensuring the detectors' field of view covers any area where a fire may occur.
