HERB recovery boilers - ANDRITZ

The Kraft recovery boiler air system consists of three levels of air ports: Primary, secondary, and tertiary that allow the heated air to enter the boiler for combustion. The strong black liquor is sprayed into the boiler between the secondary and tertiary ports through the liquor gun ports located at about 15 feet above the furnace bottom.
