1982年江西运城市木器厂设计并建成了一座装材量为7米~3的双递流周期式强制循环型太阳能远红外木材干燥窑。该干燥窑年烘干木材量500米~3,烘干周期4天左右,干燥成本低于6元/米~3。鉴于太阳能利用受季节、气候和昼夜变化的影响,具有间歇性的特点,就利用锯末作为太阳能的远红外木材干燥窑的辅助能源,从而保证了木材干燥过程的充足用热和生产工艺的连续性。该窑主 In 1982, Yuncheng Woodworking Plant of Jiangxi Province designed and built a double-circulation cycle type forced-circulation solar far-infrared wood drying kiln with the installed capacity of 7m ~ 3. The drying kiln drying wood volume 500 m ~ 3, the drying cycle of about 4 days, the drying cost of less than 6 yuan / m ~ 3. Given the intermittent nature of solar energy use due to seasonal, climatic and diurnal variations, the use of sawdust as an auxiliary source of solar far-infrared wood kilns ensures adequate heat use and continuity of the production process for the wood drying process .
