The primary air flow rate is specified as a constraint that specifies the primary air to coal flow ratio as a function of coal feed rate (mill curve). In other words, the primary and secondary air flow rates is controlled in proportion to the coal feed rate as in a typical ratio control loop. Figure 3: Coordinated Control
