Let's break down our discussion from last week, specifically, how we can Be Safe while operating an oxidizer.
An UNPROTECTED regenerative thermal oxidizer (RTO) is ripe for an explosion. A process exhaust stream that goes into this type of incinerator is often of varying energy content and can have solvent loads that change rapidly in a matter of minutes. Danger is present when the inlet stream to the incinerator suddenly gets rich enough to ignite or explode. To 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. This can save the oxidizer from destruction by fire or explosion.
So in order to Be Safe & withstand this particularly harsh environment, the analyzer should:
- Measure a wide range of chemicals
- Have a very fast response time
- Be fully heated
- Constructed of Strong Materials (hard-coat aluminum)
Being Safe has an added perk... it can help you protect your investment.
