The inlet streams of most oxidizers contain a mixture of VOC's in differing proportions and concentrations, some even process streams of unknown content. These variations can have solvent loads that change rapidly in a matter of minutes; danger is present when the stream suddenly gets rich enough to ignite or explode. To stay safe and prevent this from happening a flammability analyzer is necessary.
NFPA 86, the National Fire Protection Association's Standard for the Safe Operation of Ovens and Furnaces, defines direct-fired thermal oxidizers as Class A Furnaces mandating the use of continuous Flammability Analyzers on inlet streams exceeding 25% LFL. The analyzer’s job is to activate warning and danger alarms before the inlet stream reaches 50% LFL (operation above 50% LFL is not permitted). This can save the oxidizer from destruction by fire or explosion.
- Measuring flammability by installing a PrevEx Analyzer at the inlet of the oxidizer will prevent fires, explosions, or catalyst destruction by monitoring the flammability of the incoming VOC stream.
