Abstract

In the work, experimental thermal imaging studies were carried out at an industrial enterprise of the temperature regimes of operation of large-sized continuous convective dryers. Photographic surveys and scanning of the distribution of the temperature field in a pile of lumber during the period of unloading from the chamber of the drying plant were carried out using thermal imaging equipment. According to the results of the analysis of the data obtained, an increased temperature background is noted in the lower part of the stack, which is obviously associated with a more significant energy supply in this part of the lumber stack. The experimental data obtained indicate an uneven field of energy carrier velocities, and hence temperatures in the block of distribution of physical quantities for heat treatment of the material along the height of the drying chamber.
