Published By Publication Date Number of Pages
TAPPI 2018 3
]]> TAPPI TIP 0404-17 provides instructions for calculating the theoretical air volume requirements to achieve recommended average pocket humidity in two-tier dryer sections with conventional top and bottom dryer fabrics. Single-tier dryers do not have conventional dryer pockets, so ventilation requirements are different for these sections. This TIP does not provide information for designing pocket ventilation and runnability components. Rather, it specifies the minimum amount of air that must be delivered to dryer pockets to keep pocket humidities at acceptable levels. Some ventilation devices do a better job delivering ventilation air than other devices. This TIP simply specifies the minimum amount of air that should be delivered.
