The configuration of the coal mills of boiler units is in two rows on either side of the boiler with one stream of three mills and another stream of four mills on the other side of boiler.there are seven mills in each unit i.e. total 14 mills in two units. each mill is provided with collection and conveying equipment as defined above.
Coal and the high temperature inside the mill lead to rapid oxidation of the coal. this results in further heat buildup and the potential forire. if the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to.
Dent detection in this area would give the operator additional knowledge of changes in mill conditions. another area for infrared detector application is the coal feed inlet connection toill. operators would be informed of fires entering the mill from storage. plants utilizing this knowledge would be able to eliminate the risk.
