Apr 01, 2014 The mill model is running in parallel with the power plant coal mill operation the measured and predicted outputs are displayed on the computer screens in the power plant control room. When the measured and predicted mill outputs are over the pre-set threshold values, the system will raise alarm reports to give warning signals.
In a typical coal power plant, lignite soft coal and anthracite hard coal are stored temporarily in bins up to 15 meters high. To ensure that the coal belts are continuously loaded without interruption, a robust and reliable level measuring system is required. Additional point level detectors are used to prevent any overfilling of the bins.
