a multiplexed system sampling six measurement points, or each point every 10 to 15 minutes, would be much too slow. The Millwatch system proved its value in 2013 when it showed rapidly rising CO levels in the outlet of one of the coal mills. It would have taken at least 15 minutes for the temperature and fire detection systems

In the mills, the solid fuel is pulverised and entrained by the preheated primary air stream to the burners [6]. The homogeneity of the fuel particle distribution between the burners fed by a given mill is generally checked during commissioning, using manual flow rate measurements based on isokinetic sampling of the particles in the feed lines.

Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coalfilled silos and in cyclones or bag houses that are not being used, while imprecise O2 levels in inert coal mills can also present a significant danger. In either situation, selfignition is a real possibility.
