2017-1-16·fired boilers the primary air is only separated from the secondary air at the burners. In coal-fired boilers the required aircoal ratio of the mixture leaving the pulverizers ranges from 1.2:1 to about 2.2:1 and is generally near 2:1 for vertical spindle mills. Thus the amount of primary air is relatively low compared with the amount of
