Monitoring of coal pulverizers

The mill module monitors the operating conditions of the mill itself, along with the influence of the mill assembly operation on the incomplete combustion loss in the boiler.

Operators can observe the following parameters:

 

• The working point as regards the unit power consumption for coal pulverising, as presented in the graph that has the following coordinates: unit ventilation and classifier position. The operator can see the actual working point in the form of the current value of unit power consumption, and also a series of statistically averaged characteristics of mill ventilation (the working point for the reference conditions). It results in a deviation from the standard which may be caused either by the deterioration of the pulverising component condi-tion, or the fuel quality.
• The working point as regards the unburned parts content in fly ash is presented in the graph that has the following coordinates: unit ventilation and classifier position. In this case, these coordinates mean the weighted averages for the assembly of mills in operation. As in the first example, there are two working points: the actual working point (Cp laboratory measurement), and the working point for the averaged (standard) conditions).
