Pulverized Coal Pipe Testing and Balancing

Pulverized Coal Pipe Testing and Balancing

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.

Fineness an overview ScienceDirect Topics

Fineness an overview ScienceDirect Topics

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.

A Comparison of Three Types of Coal Pulverizers

The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

Pulverizer Vibration Issues

The end result is that pulverizer fineness at the lower loads increases. On pulverizers with 75% passing 200 Mesh fineness at full load, minimum load fineness can be as high as 85% or more. In some instances, an excessive quantity of finely ground coal particles on the bowl acts as a powder lubricant between the roll and bowl.
