【目的】探明不同类型生物质新能源烤房的烘烤性能,筛选适宜的生物质新能源烤房,为生物质烤房在烤烟生产上推广应用,促进烤烟生产节能减排、减工降本及提质增效提供理论依据。【方法】对比分析生物质内置式烤房、生物质外置式烤房和普通烤房在用工成本、能耗成本、烟叶经济性状及烟气排放指标等方面的差异。【结果】生物质内置式烤房用工成本分别较生物质外置式烤房和普通烤房降低0.14元/kg和0.38元/kg,降幅分别为30.43%和54.29%;能耗成本分别降低0.86元/kg和0.42元/kg,降幅分别为34.26%和20.29%;烤后烟叶均价分别增加0.81元/kg和1.89元/kg,增幅分别为2.88%和6.99%;上等烟率分别增加1.59百分点和5.51百分点;综合经济效益分别提高7.57%和10.35%。2种生物质烤房SO_(2)和颗粒物的排放均较普通烤房降低70%以上。【结论】生物质内置式烤房在节能减排、减工降本及提质增效方面效果最好,具有较好的推广应用前景。

【Objective】The curing performance of different types of new biomass energy curing barn is explored and the suitable new biomass energy curing barn is screened to provide the theoretical basis for popularizing and applying biomass curing barn in the production of flue-cured tobacco,promoting energy saving and emission reduction,labor saving and cost reduction,and quality improvement in production of flue-cured tobacco.【Method】The variation in labor cost,energy consumption,tobacco economic traits and smoke emission index are studied by comparing and analyzing three curing barns(biomass built-in curing barn,biomass external curing barn and conventional curing barn).【Result】The labor cost of biomass built-in curing barn is decreased by 0.14 Yuan/kg and 0.38 Yuan/kg compared with that of biomass external curing barn and conventional curing barn,with a decrement of 30.43%and 54.29%;The energy consumption cost is decreased by 0.86 Yuan/kg and 0.42 Yuan/kg,with a decrement of 34.26%and 20.29%;The average price of cured tobacco is increased by 0.81 Yuan/kg and 1.89 Yuan/kg,with an increment of 2.88%and 6.99%;The proportion of superior-class tobacco is increased by 1.59 percentage and 5.51 percentage;The comprehensive economic benefits are increased by 7.57%and 10.35%.Compared with the conventional curing barn,the SO_(2),particulate matter and other emissions of the two biomass curing barns are reduced by more than 70%.【Conclusion】The biomass built-in curing barn has the best effect on energy saving and emission reduction,labor saving and cost reduction and quality improvement,which has better promoting and applying prospect.
