Abstract: The paper aims to explore the utilization of biomass fuels in tobacco leaf curing, and achieve energy saving, environmental protection, cost reduction and efficiency increase. The lower leaves and the middle leaves of‘Xiangyan 5’were taken as experimental materials, we compared the application effect of biomass particle combustion furnace with corresponding heat exchanger, direct docking metal heating equipment and direct docking non- metal heating equipment with the effect of a one- time coal non- metallic heating equipment, to study the application of biomass particle combustion furnace. The results showed that: the use of biomass particle combustion furnace for tobacco leaf curing was beneficial to the control of dry bulb temperature during the process, dry bulb temperature control precision was within ±0.5℃, ensuring that the curing process was in place and beneficial to improve the quality of tobacco leaf baking. The energy cost was lower than coal curing, and the operation, including fuel feeding, ignition, control and removal of slag, was much easier and labor saving than traditional coal-fired way. The biomass particle combustion furnace showed good application effect with the corresponding heat exchanger, followed by that with the direct docking metal heating equipment, and the application effect of the direct docking non-metal heating equipment was relatively poor.
