Energies Free Full-Text Modeling of Coal Mill

Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional data-driven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the analysis of primary air system

In practice, when the coal feed rate to a direct-firing system is varied, the rates of air flow though the mill is varied proportionally between 70 percent and 100 percent. Tests have shown that continuous adjustment of the airflow rate over the mill loading control range considerably improves the control behavior of roller grinding mills.
