An innovative approach to condition-based maintenance of coal grinding subsystems at thermoelectric power plants is proposed in the paper.
Coal mill grinding tables become worn over time and need to be replaced through time-based maintenance, after a certain number of service hours.
At times such replacement is necessary earlier or later than prescribed, depending on the quality of the coal and of the grinding table itself.
Considerable financial losses are incurred when the entire coal grinding subsystem is shut down and the grinding table found to not actually require replacement.
The only way to determine whether replacement is necessary is to shut down and open the entire subsystem for visual inspection.
The proposed algorithm supports condition-based maintenance and involves the application of T 2 control charts to distinct acoustic signal parameters in the frequency domain and the construction of Hidden Markov Models whose observations are coded samples from the control charts.
In the present research, the acoustic signals were collected by coal mill monitoring at the thermoelectric power plant “Kostolac” in Serbia.
The proposed approach provides information about the current condition of the grinding table.
