ANALYSIS OF DIFFERENT WOOD DRYING METHODS FROM ENERGY USAGE POINT OF VIEW

Abstract

The goal of work is to present several different methods of wood drying and to analyse their performance on the example of two wood species (beech and pine). The emphasis of the analysis is energy aspect of performance, along with economy analysis also done.Comparatively is analysed drying of both wood species using: conventional kiln with 3 different fuel types, heat-pump assisted kiln, with and without natural pre-drying. The results have shown that better energy usage performance of drying does not necessary imply more profitable drying.
