Abstract: The coal-pulveriser/coal mill is an important subsystem upstream of boilers in coal-based thermal power plants. The efficient boiler operations demand optimum combustion-air to coal-fuel ratio (AFR). In fact, a portion of (preheated) combustion air, called primary air, passes through the coal mill and carries pulverised coal to the ...
