炎検知技術について
引火の危険性を監視するニーズに対応した適切な製品を決定する方法
引火の危険性を監視するニーズに対応した適切な製品を決定する方法
炎は、燃料源によって、赤外線（IR） 波長、可視光線波長、紫外線（UV）波長の電磁放射を放出します。炎によっては人間の目に見えないため、今日の炎検知器には、炎の検知に光学技術が採用されています。さまざまな燃料源を検知するために、UV、UV/IR、およびマルチスペクトル赤外線を活用して光学炎検知技術が開発されました。これらの炎検知製品は、本物の炎かどうかを判断する際、スペクトル帯域で放出される放射の見通し検知に依存しています。
検出しようとしている可能性のある火炎が炭化水素ベースか、または非有機かどうかを考慮してください。 炭化水素の火炎では、メタンと酸素の組み合わせが二酸化炭素と水を生み出します。 この種の火災では、UV 信号の読み取りが 0.2 ミクロン、IR 信号の読み取りが 2.7 ミクロンと 4.5 ミクロンとなります。 水素の火炎では、水分子のみが生じるので、炭化水素の火炎で生み出されることが知られているのと同じ CO2 ピーク値を見ることはありません。
太陽光、落雷、高熱物体、その他の非火炎源などの環境の状況が誤報を発する場合があります。 炎検知器で、実際の火災と偽の放射源との区別できることが非常に重要です。
炎検知の技術は効果的に異なる距離の炎を認識します。 必要とする検出範囲内で作動できる検出器を活用することが重要です。
光学的フレイム検出装置には、カメラのレンズと同様な「視野」の範囲が付いています。 この「視野」の範囲を考慮に入れると、設置場所、または設置場所内の特定の領域を網羅するのに何台の検出装置が必要であるかを決める際に役立ちます。
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.
