密集烤房使用不同类型燃煤烘烤效果研究

Intensive Curing Barn with Different Type Coal Baking Effect Research

[目的]结合大理州烟叶烘烤使用燃料的现状,研究密集烤房使用不同类型燃煤的烘烤效果。[方法]以普通蜂窝煤为对照,自制蜂窝煤、生物质燃料、褐煤、贫煤、无烟煤5种在用燃料为处理,试验重复5次,研究标准密集烤房烘烤过程中各种燃煤的烘烤效果。[结果]试验表明,高发热值无烟块煤烘烤效果最好,相比对照1 kg干烟降低烘烤成本0.26元,提高均价1.62元,减少硫排放52%;褐煤虽然烘烤成本最低,但均价也最低,比对照少2.81元/kg,温湿度控制也最不准确,是所有参试燃料中最差的一种;除生物质燃料外,烘烤过程中随着燃料燃烧值的提高,烘烤燃料成本逐步降低,温湿度控制准确性逐步提高。[结论]研究可为大理州地区烘烤燃料科学使用提供借鉴依据。

[ Objective ] Combined with fuel utilizing status in tobacco curing process in Dali State, the baking effect of various coals in intensive curing barn was studied. [Method] With ordinary honeycomb briquette as control, homemade honeycomb briquette, biomass fuel, lignite, lean coal, anthracite as treatment, repeating 5 times, the baking effect of various coals in standard intensive curing barn was studied. [ Result] The test results showed that the higher calorific smoke-free lump coal has the best baking effect, compared with controls reduce the baking cost 0.26 yuan per kilogram of dry smoke, improve the average price of 1.62 yuan, reduce sulfur emissions by 52% ; Lignite, while the lowest cost of baking, average price is the lowest, less than 2.81 yuan per kilogram, control temperature and humidity control is also the least accurate, is one of the worst of all the volunteers＇fuel; In addition to the biomass fuel, with the improvement of fuel combustion value during the process of baking, baking gradually reduce fuel costs, temperature and humidity control accuracy improved. [ Conclusion] The study can provide reference basis for scientific use of baking fuel in Dali State area.
