To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
The advantages of ball and race mill are as follows: Lower capital cost. Lower electricity power consumption. Lower workspace required. Lower weight. However, in ball and race mill there is greater wear as compared to other coal pulverizers. The usage of pulverized coal as a fuel has now become the standard method of firing in many huge boilers.
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.
