COMBUSTIBLE WOOD FLOUR - "Factory fire causes $350000 damage"

Articles like this always catch my eye: "Factory fire causes $350000 damage"

Over the years I have helped protect many of these wood flour producers. 
This fire was likely caused by the dryer.  Although many are also started in the grinding process. 
For a wood flour composite extrusion process like this,  they will typically dry wood flour to just below combustion  point, creating a highly flammable combustible material 
and dust in the process.  

They will typically use pneumatic conveying of the dried wood flour from the dryer to the process.  
Depending on how the conveying, collection and storage systems are designed, this wood flour can also agglomerate and create stalactites and material build-up
within the ductwork at any joints, elbows and transitions, and also any joints or corners of the dust separator or collector. 
These stalactites can super heat in the hot air stream from the dryer, creating red-hot ignition points within the ductwork and collector.

This article written for Security Shredding and Storage News talks about Fire Safety for the Secure Shredding Industry.  If you have combustible dust - we can help.

I saw this posted on John Astad's (Combustible Dust Policy Institute) Facebook page:Tom Andel, columnist and blogger for Modern Materials Handling (mmh.com), and a contributor to Logistics Management, shares with readers preventing and mitigating fire potential in a shredding operation.
