Aug 31, 2020 · Abstract: The coalpulveriser/coalmill is an important subsystem upstream of boilers in coalbased thermal power plants. The efficient boiler operations demand optimum combustionair to coalfuel ratio (AFR). In fact, portion of (preheated) combustionair called primaryair, passes through coalmill and carries pulverised coal to the boiler.

To summarize the coal mill controls, they may be divided basically into two major egories:. 1. To control the quality of coal being sent to the burners loed 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.
