Auswahl der richtigen Technologie für frühzeitige Erkennung von Flammen
Abhängig von der Brennstoffquelle senden Flammen elektromagnetische Strahlung mit den Wellenlängen des Infrarotbereichs (IR), des sichtbaren Lichts und des ultravioletten Bereichs (UV) aus. Da einige Flammen für das menschliche Auge unsichtbar sind, werden in modernen Flammendetektoren zur Erkennung von Flammen optische Technologien eingesetzt. Die entwickelten optischen Flammensensortechnologien verwenden UV-, UV/IR- und Multispektrum-Infrarotstrahlen, um Flammen unterschiedlicher Brennstoffquellen zu erkennen. Diese Flammendetektionssysteme basieren auf der Erkennung – mittels Sichtlinie – der in Spektralbändern ausgesendeten Strahlung, um zu bestimmen, ob es sich tatsächlich um eine Flamme handelt.
Überlegen Sie, ob die potenzielle Flamme, die Sie erkennen möchten, auf Kohlenwasserstoff basiert oder anorganisch ist. Bei Kohlenwasserstoffflammen werden durch eine Kombination aus Methan und Sauerstoff Kohlendioxid und Wasser erzeugt. Diese Art von Feuer erzeugt einen UV-Signalmesswert bei 0,2 Mikron und einen IR-Signalmesswert bei 2,7 Mikron und 4,5 Mikron. Wasserstoffflammen erzeugen nur Wassermoleküle. Deshalb sehen wir nicht den gleichen CO2-Spitzenwert, der bekannterweise eine Kohlenwasserstoffflamme erzeugen kann.
Umweltbedingungen, wie z. B. Sonnenlicht, Blitzschläge, heiße Objekte und andere Quellen, die keine Flammen umfassen, können Fehlalarme auslösen. Es ist äußerst wichtig, dass der Flammendetektor zwischen einem tatsächlichen Feuer und einer falschen Strahlenquelle unterscheiden kann.
Technologien für die Flammenerkennung erkennen wirksam eine Flamme aus unterschiedlichen Entfernungen. Es ist wichtig, einen Detektor einzusetzen, der innerhalb Ihres erforderlichen Erkennungsbereichs arbeitet.
Optische Flammendetektoren werden mit einem „Sichtfeld“-Bereich geliefert, welcher dem Objektiv einer Kamera gleicht. Unter Berücksichtigung des Sichtfeld-Bereichs kann bestimmt werden, wie viele Detektoren benötigt werden, um eine Installation oder einen spezifischen Bereich innerhalb der Installation abzudecken.
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.
