Pulverizer Capacity is not simply “tons throughput per hour!” While throughput is large factor in pulverizer capacity, many other aspects can dramatically affect your mills’ performance. Often times, it is the smaller details such as critical tolerances and the condition of the grinding elements.
and classification in the pulverizer tends to reduce quartz survival, while staged firing, substochiometric conditions in the burner zone, for NOx control will increase the survival factor for quartz. In order to quantify fly ash erosion, Raask developed an index analogous to the abrasion index for coal.
