We imposed limits on the silos top layer which allows us to suspend fuel additives in case coal characteristics change dramatically. Accutrack is definitely a good solution that allowed us to track the coal from the pile to the mills. Like always, technical support is great as well as response time.
Aug 29, 2010· Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.
