Как выбрать подходящие решения для мониторинга воспламеняющихся веществ.
Современные извещатели пламени используют оптические технологии для обнаружения пламени. Известно, что пламя излучает электромагнитные волны в виде инфракрасных волн (IR), видимого света и ультрафиолетовых волн (UV) в зависимости от источника топлива. Поэтому оптические технологии обнаружения пламени были разработаны c учетом UV, UV/IR и многоспектрального инфракрасного излучения. Данная продукция основана на обнаружении излучения, испускаемого в спектральных полосах, чтобы определить, является ли пламя реальным.
Учитывайте тип горючего, от которого потенциально возможно возгорание, для обнаружения важно, будет ли это углеводородное или неорганическое пламя. При обнаружении углеводородного пламени сочетание метана и кислорода образует углекислый газ и воду. Этот тип пламени создает УФ-сигнал с показаниями 0,2 мкм и ИК-сигнал с показанием 2,7 мкм и 4,5 мкм. Водородное пламя производит только молекулы воды, и поэтому мы не видим того же пика CO2, который, как известно, производит углеводородное пламя.
Условия окружающей среды, такие как солнечный свет, молния, горячие объекты и другие источники без пламени могут вызывать ложные тревоги. Очень важно, чтобы детектор пламени мог различать фактический огонь и источник ложного излучения.
Технологии обнаружения пламени эффективно распознают пламя на различных дистанциях. Важно использовать детектор, который может работать в пределах необходимого диапазона обнаружения.
Оптические датчики пламени поставляются с диапазоном «зоны обзора», аналогичным линзе на камере. Принимая во внимание диапазон зоны обзора, вы сможете определить, сколько детекторов необходимо для покрытия установки или конкретной области в рамках установки.
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.
