3.12.Solar timber kilns
Numerical simulation and experimental measurement were used byTaylor and Weir, to examine the performance of aglasshouse-type solar timber dries about 5 m3 of timber from green to equilibrium in about 3 weeks.It was found that fastest drying is obtained from a design with low heat capacity but good(forced) circulation of air through the timber stack. Analysis of the evolution in solar heated drying kilns in recent decades shows that there have been a series of modifications to optimize their thermal and drying efficiency.Using an analysis method based on product design,Luna et al. reported on existing solar timber kilns ; the different dryers and their component units were studied ; developments were noted, focusing on changing trends in technological systems and as a result of this analysis some future adaptations were suggested.
