Cómo determinar los productos adecuados para sus necesidades de monitorización de peligros relacionados con llamas.
Las llamas emiten radiación electromagnética en las longitudes de onda infrarroja (IR), de luz visible y ultravioleta (UV), según la fuente de combustible. Dado que algunas llamas son invisibles para el ojo humano, los detectores de llamas actuales utilizan tecnologías ópticas para detectar llamas. Se han desarrollado tecnologías ópticas de detección de llamas con UV, UV/IR e infrarrojo multiespectro para detectar llamas de diferentes fuentes de combustibles. Estos productos de detección de llamas se basan en la detección de línea visual de la radiación emitida en las bandas espectrales para determinar si una llama es real.
Tenga en cuenta si la potencial llama que intenta detectar estará basada en hidrocarburos o será inorgánica. Con las llamas de hidrocarburos, una combinación de metano y oxígeno produce dióxido de carbono y agua. Este tipo de fuego crea una lectura de señal UV a 0,2 y una lectura de señal infrarroja a 2,7 y 4,5 micrones. Las llamas de hidrógeno solo producen moléculas de agua y, por lo tanto, no vemos el mismo pico de CO2 que una llama de hidrocarburo puede producir.
Las condiciones ambientales como luz solar, rayos, objetos calientes y otras fuentes de calor que no son llamas pueden provocar falsas alarmas. Es crítico que el detector de llama pueda distinguir entre un incendio real y una fuente de radiación falsa.
Las tecnologías de detección de llamas reconocen de manera efectiva una llama a diferentes distancias. Es importante utilizar un detector que pueda operar en su rango de detección requerido.
Los detectores de llama ópticos incluyen un rango de “campo visual” similar al lente de una cámara. Tomar en cuenta el rango de campo visual ayuda a determinar cuántos detectores se necesitan para cubrir la instalación de un área específica dentro de la instalación.
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.
