    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

    Advanced Control Algorithm for Coal Mill - ScienceDirect

    Jul 01, 1999 The principal control of the coal mill is the raw coal in-feed according to the load variation, which is indicated by the variation of the main steam pressure. The quantity of the in-feed raw coal is therefore the control variable and the steadiness of main steam pressure is the control target. This papel deals mainly with the control of the fan-type coal mill for the direct firing system of the boiler
