Experimental and Theoretical Study of heating/Drying of Moist Paper Sheet With a Gas-Fired Infrared Emitter

摘要

Infrared (IR) radiation is used for heating/drying of moist paper in the paper making process owing to its penetration characteristic inside porous media and a high absorp- tivity of water in the IR wavelength range. However, there is a lack of fundamental understanding of the transport phenomena occurring within moist paper during IR heating/drying. A series of experiments has been conducted along with the development of a theoretical model to fundamentally understand IR heating/drying of moist paper.
