SUMMARY

The discussion focuses on the search for an intrinsically safe combustible dust monitor specifically for wood dust from pellets, capable of handling concentrations of 50g/m³ in a coal bunker environment. Participants suggest various solutions, including the use of a Davis lamp for gas monitoring and optical monitoring techniques, but emphasize the lack of suitable products that meet the safety requirements. A potential candidate, the Ducon MIP 3188AZL, was identified, though its specifications initially caused confusion regarding its dust monitoring capacity.

PREREQUISITES
  • Understanding of combustible dust monitoring standards
  • Familiarity with intrinsic safety requirements in hazardous environments
  • Knowledge of optical monitoring techniques for particulate matter
  • Experience with dust concentration measurement units (g/m³)
NEXT STEPS
  • Research intrinsic safety standards for combustible dust monitors
  • Investigate optical monitoring technologies for particulate density measurement
  • Explore the specifications and applications of the Ducon MIP 3188AZL monitor
  • Learn about the Davis lamp and its potential adaptations for dust monitoring
USEFUL FOR

Safety engineers, industrial hygienists, and facility managers involved in monitoring combustible dust in industrial settings, particularly those working with wood pellets and coal dust.

I have been tasked with what seems an almost impossible feat. It sounds simple but for some reason it is not.

I am looking for a device that can monitor combustible dust, in this case wood dust from pellets. It must be able to handle concentrations of 50g/m^3. The area to be monitored is a coal bunker, roughly 80’ tall and 20’x50’.

And most important it must be intrinsically safe! This has been my biggest problem. I have found a handful of suitable monitors yet they are not intrinsically safe. Who designs a combustible dust monitor that could end up being the source of an explosion?!

Any help would be greatly appreciated.

unfortunately they don't deal with dust monitors.
 
Would the old Davis lamp perhaps work for you?
It was admittedly used for combustible gas, rather than dust, but I would think that fine dust would be pretty equally diffused in a factory setting and would pass pretty reliably through the screen mesh of a Davis lamp.
 
If the coal dust is the only particulate matter in the air in that enclosure, maybe think about using a scanning laser beam and optical monitoring to figure out the density of dust in the air... Very intrinsically safe.

Yes it would work, But I can't find a product that exists.

That monitor was looking ideal for the application, until I noticed in the specifications: "Maximum dust = 2g per cubic liter. The OP is asking to monitor up to 50g per cubic liter.

No, per cubic meter! That's 0.05 g/L.

OOPS! Sorry. Thanks for catching my mistake.
