Sažetak
High costs, irrational consumption of thermal energy and low efficiency are often characteristics of sawn timber drying by warm humid air in chamber drying kilns. A weak link between technological planning with the sawn timber mass dynamics in the systems with more drying kilns is the most common reason that influences considerably the economy of timber thermal processing and the heat source pre-dimensioning. Lack of experimental research and usage of general relations are common reasons for insufficient practical compliance and connection of drying thermal needs and the heat source capacity. Air heater thermal load has been researched during the sawn oak timber drying, 25 mm thick, as well as 32 mm and 50 mm thick beech, by applying of appropriate regimes during all the stages in more cycles of convective drying. Current thermal needs have been measured and registered in relation to maximal values during the characteristic intervals of each drying cycle. The exact values have been shown, while the defined correlation polynome has been used to describe a graphic and mathematical model of thermal load in all intervals of tested sawn timber drying cycles. An analytical procedure for determination of total maximal thermal needs of more drying kilns has been suggested based on timber moisture decreasing and technological drying planning. Using a characteristic example, its applicability and contribution to an optimal thermal source dimensioning has been shown.
