空气热-煤混合能源烤房在烟叶烘烤中的应用效果

Application Effect of Air Heat-Coal Mixed Energy Barn in Tobacco Flue-curing

为空气热-煤混合能源烤房在烤烟生产上的推广应用提供科学依据,进行了空气热-煤混合能源烤房与普通燃煤烤房对考后烟叶质量及经济效益的对比试验。结果表明:空气热-煤混合能源烤房的最佳经济结合点为50℃转火,即在50℃前用热泵加热,达到50℃后改用煤炉加热。与普通燃煤烤房相比,空气热-煤混合能源烤房可以节约能源资源消耗46.8%;每烤房单次节省烘烤费用128.9元,节省率20.7%;烤后烟叶上等烟比例较高,低次等烟比例很低,烟叶外观质量最佳,农民销售收入增加28.4%;烤房耗煤量低,产生的粉尘和大气污染物排放量减少57.8%。

To provide a scientific basis for air heat-coal mixed energy barn popularization and application in the production of flue-cured tobacco, a contrast test of flue-cured tobacco quality and economic benefits was conducted between air heat-coal mixed energy barn and ordinary coal-fired barn. The results showed that it was best to heat the barn using heat pump before 50℃ and then using coal stove. Compared with ordinary coal-fired barn, air heat-coal mixed energy barn could save energy and resources consumption by 46.8%; Saved per barn baking costs 128.9 Yuan（saving rate 20.7%）; High- class flue-cured tobacco accounted for a higher proportion while low-class flue-cured tobacco accounted for a low proportion, the appearance quality was the best and peasants＇ incomes were enhanced by 28.4%; the dust and air pollutant emissions was reduced by 57.8% as the coal consumption decreased.
