Fire Detection Methods for Coal Pulverizer Systems

The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table, and at the fan exit for exhauster systems. These are the prime locations of fires.
