  • Boiler Performance and Mill Outlet Temperature Bright

    The mill outlet temperature of coalair mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal In the case of high volatile coal, while the lower limit generally remains as 65 degree centigrade, the upper limit is restricted to a lower level depending on percentage of volatile content in coal This is mainly done to avoid mill fire and mill explosionThe outlet temperature of the coal mill is maintained at desired point so that the coal delivered from the mill is completely dry and achieves the desired temperature Also, in case of high temperature at the mill outlet, cold air is blown in to reduce the risk of fire 5142 Discussion Normally, the entire requirement of PA flow necessary for a particular load at the mill is initiallyCoal Mill an overview | ScienceDirect Topics
