Dear sir:

Sparkle is a metal particle that is burning, is moving at high speed through the ducts and cyclones. It is very similar to the sparks that come out when these metal polishing materials.

to extinguish must cool its surface, this is achieved by stirring the air around the spark. cyclones are supposed to do this, however in practice they are not very efficient (I speak of high efficiency cyclones, cylindrical bodies of small diameter and long cones). I tried to solve this problem using cyclones with metal chains inside, but did not work, the problem diminished but not eliminated. I decided to put a spark arrestor in the ducts before reaching the collector, that was the solution
