The waste heat recovery device with forced centralized exchange air of wood drying chamber was studied, and the energy-saving effect was tested and analyzed. The temperature of the wet-heat and fresh air was tested in different drying phases. Results show that the wet-heat air temperature decreases 13℃to 16. 3℃and the fresh air temperature increases 9℃ to 11.9℃ after they pass through the equipment. The heat recovery rate of this device is 18.6% to 28%, and the average rate is 22%. In theory calculation, the total exhaust energy, after drying Manchurian ash per 1m^3 with 47mm thickness, is 1.4 × 10^6 kJ. Application of this device can save energy 2. 88 × 10^5kJ, which is the same as saving normal coal 9. 84kg.
