Abstract: The purpose of this study was to improve fuel efficiency, reduce curing costs and reduce environmental pollution of flue-cured tobacco bulk curing. Compared with the bulk curing using common heating equipment, the comparative study of flue-cured tobacco baking performance with efficiency heating equipment was developed. The new heating equipment was the double monomer heating technology curing barn with positive and negative combustion way. The results showed that using a heating furnace with up and down hearth, forward and reverse burning at the same time to achieve the combustion of coal burning more fully. CO, CH4, carbon dust and other combustible materials of conventional flue gas contained can be fully, efficient combustion and utilization. The temperature raising speed of idling test was 60℃/h, it was 34℃ higher than that of ordinary curing barn. When the system baking real load, the match degree of measured temperature and humidity is high with the target temperature and humidity in different stages and it can completely meet the control requirements of baking technology. Double heating curing barn with the positive and negative combustion monomer average coal consumption, power consumption and comprehensive energy consumption costs of per kilogram dry tobacco reduce 0.31 kg, 0.05kWh and 0.33 yuan, and the decline was 17.73%, 14.36% and 17.46% than ordinary curing barn, respectively. The baking operation and other daily labor costs per kilogram dry tobacco was less than ordinary heating equipment such as 0.52 yuan, fell 43.93%, and no significant negative effect on the quality of tobacco curing. The double monomer heating technology with positive and negative combustion way can improve heating speed and plane temperature uniformity, the baking temperature and humidity control in the process was precision. This way can effectively reduce the energy consumption and labor costs of tobacco-curing system.
