The air preheater (APH) temperature control system comprises at least a first APH or combustion / secondary air bypass duct in metered communication with a combustion air inlet duct and a secondary air duct, the first APH or combustion / secondary air bypass duct adapted in use to bleed a portion of the combustion air from the air inlet duct upstream of the APH 100 as a secondary air bypass and reintroduce it into the downstream secondary air duct, and a flow control device for metering or controlling the volumetric flow rate of the secondary air bypass and regulating the primary air flow, the flow control device being adapted in use alone or in combination with other regulating means to regulate the T10 MIN ~T10 MAX and a flow control device operable to maintain the flue gas outlet temperature at or above a desired minimum predetermined temperature for the incoming flue gas volumetric flow rate exiting the APH to maintain the mill outlet temperature within a safe range of .
