The low temperature waste heat recovery in drying process of pine wood using micro-jet heat exchanger
Journal Title: Annals of WULS, Forestry and Wood Technology; Zeszyty naukowe SGGW - Year 2016, Vol 95, Issue 1
Abstract
The article presents the influence of the drying medium temperature changes for the relative and absolute moisture content values during pine wood (Pinus sylvestris L.) drying. The drying process was conducted at constant atmospheric pressure and with different drying medium (air) temperature levels, respectively: 40o C, 60o C, 80o C, 100o C, and 120o C. In order to develop a method that would enable low temperature drying of solid materials the experiments were performed in an innovative experimental rig equipped with micro-jet heat exchanger. It was noticed that the moisture content of drying solid material achieved at a temperature not exceeding 60o C gave satisfactory results. Low temperature drying method using micro-jet air can contribute to improve its efficiency, with appropriate selection of drying time. Keywords:
