Alksnių džiovinimas aktyviąja ventiliacija

Abstract

The aim of this study was to investigate the alder as a renewable energy crop for bioluel pre paration, drying process. For the proper use of wood should dry it to 8-15% moisture. Researc conducted at the A. Stulginskis university, Heat and Biotechnological Engineering laboratory, wi two different drying variants: active ventilation (wood chips) and drying oven (whole wood). The Experimental studies have established that the most cheapest way is drying alder wit active ventilation. 50% of the moisture content of dried wood is best used when air flow not le~ than 0.113m/s. Drying is fastest, when the temperature is about 100 °C. Reducing the temperature by 30 °C degrees drying time increases by 1.6 times. Most likely to dry about 12 millimete diameter alder samples
