不同替代能源密集烤房烟叶烘烤效能对比研究

目的]探索烟叶烘烤燃煤的替代能源。方法]对生物质压块、生物质颗粒和醇基3类燃料与常规燃料(褐煤)的烟叶烘烤效能进行对比研究。结果]3种替代能源在燃烧烟气中主要污染物的排放明显低于常规燃料,烘烤过程中升温速度、稳温性能明显提高(除生物质压块外),整个烘烤工艺时间可缩短6~14 h,对初烤烟叶外观质量无明显影响;醇基燃料成本较高,烘烤综合成本约是褐煤成本的2.4倍,经济效益较差。结论]生物质颗粒燃料可作为常规燃料(褐煤)的替代能源应用于烟叶实际烘烤工艺中。

Effectiveness Comparative Study of Tobacco Curing on Different Alternative Energy Intensive Barn

Objective] The aim was to explore alternative energy of coal for baking.Method] The baking efficiency of biomass briquetting, biomass particles, alcohol and conventional fuel (lignite) was comparatively studied.Result] The results showed that alternative energy dur-ing combustion flue gas emissions of major pollutants were significantly lower than conventional fuel, heating speed, stable temperature per-formance was improved significantly (except fot biomass briquetting), baking process could be shorten 6-14 hours, no significant effect on the appearance quality of cured tobacco leaves, alcohol baking overall costs were increased by approximately 2.4-fold compared with lignite. Conclusion] Biomass particles can be used as alternative energy of conventional fuel(lignite).
