摘  要：
燃煤供热调制烟叶存在控制粗放、热效率低和污染环境等问题。为了尝试清洁能源烘烤烟叶,介绍了一种以醇基燃料为能源的新型烟叶烘烤供热设备,主要由改装的燃烧机、梭形炉膛联体散热器和自动控制仪等组成。试验验证表明,燃烧机配备0.8 gal/h和2.0 gal/h两个喷油嘴能够满足密集烤房烘烤烟叶的燃料供给;结合配装功率45 W的离心型风机和进风口开启2/3提供助燃空气,燃料可以取得最佳的燃烧效果。与传统燃煤密集烤房烘烤对比,醇基燃料密集烤房具有80%~82%系统热效率,高于燃煤密集烤房;烘烤费用干烟高出燃煤密集烤房0.64元/kg,但提高了烤后烟叶的外观质量,而且明显地降低了中部烟叶感官评吸中的杂气。在烘烤过程中,醇基燃料供热设备受自动化控制,升温灵敏,控温的精确度好于燃煤密集烤房,可以实现全程无人值守烘烤烟叶。

摘  要：
Coal-fired heating for flue curing tobacco has many negative results including extensive control,low thermal efficiency and environmental pollution,etc.In order to clean energy for tobacco flue-curing,this paper introduced an energy-heating system using alcohol-based liquid fuels for tobacco curing,which was constituted by a modified burner,spindle-shape furnace conjoined radiator,and automatic control instrument.Experimental verification indicated that 2 nozzles supplying 0.8 gal/h and 2.0 gal/h could provide enough fuel for tobacco curing.Incorporating a centrifugal-type fan of 45 W with opening the burner outlet by 2/3,the best burning result could be achieved.Compared with the traditional heating system of bulk curing barn heating system,the heat efficiency of new device was increased by 80% ~ 82%,higher than that of the conventional using coal.Although the total fuel cost of tobacco curing was 0.64 yuan/kg than that of the control,the appearance quality of tobacco after curing was improved,and the offensive oral sensation in the middle tobacco leaves was significantly reduced when evaluated by smoking.The new device could automatically and sensitively control the temperature of the loading chamber during the curing process.The precision of temperature control was better than that of the conventional coal barn.Unattended operation could be achieved during the entire curing process.
