Abstract
An adiabatic saturator receives a sample of exhaust air exiting a yankee dryer hood to determine the humidity of the exhaust air. The humidity is determined by temperature readings of the exhaust air, saturated air exiting the interior of a saturator cell, and water supplied to the saturator cell interior. An air distributor in the saturator cell interior promotes saturation of the exhaust air and a backflush mechanism backflushes the saturator cell interior to keep the water in the cell interior clean.
