Abstract

The effect of various factors on the efficiency of infrared (IR) dryers has been studied by modeling and simulation of radiative heat transfer in these dryers. Generally, 20-35% of the radiation from electrical IR dryers becomes absorbed by the web, whereas in the case of a gas-fired dryer 30-50% of the energy becomes absorbed. The efficiency is strongly dependent on the dryer design, power, geometry, cleanness, and the material to be dried.
