Experimental evaluation of electric infrared dryers

Petterson, Magnus and Stenström, Stig LU (2000) In Tappi Journal 81(8). p.89-107
Abstract
Infrared (IR) dryers are widely used in the paper industry for drying coated paper grades.

However, there is limited knowledge regarding the efficiency of IR dryers. This study was

undertaken to investigate the radiation efficiency and the total efficiency of electric IR dryers.

Radiation efficiency was measured in the laboratory and on an industrial machine. The results

indicate that radiation efficiency increases with increasing power and is just above 60% at full

power. Total efficiency—the fraction of supplied power that ends up in the paper web—was

measured on a small off-machine coater. The results indicate a total efficiency of approximately

40%. Problems and... (More)
