立式炉热风室烤房试验初报

An Experiment of the Heated Air Chamber with a Vertical Stove

采用立式炉热风室烤房与旧式烤房进行性能对比 ,此外增设对立式炉膛规格尺寸作部分修改的处理 ,分别就腰叶和上二棚叶进行烘烤。试验结果表明 :处理 1、2烤房性能优于对照 ,烘烤烟叶鲜干比降低 ,单叶重提高 ,上等烟增加 8.0 5～ 15 .39个百分点 ,均价提高 0 .5 5～ 2 .5 1元 /kg,每 1kg干烟耗煤减少 0 .5 9～0 .78kg,节煤率达 35 .33%～ 4 8.5 5 %。处理 1与处理 2之间没有差异。

The comparison experimental results from the baking property of middle and upper tobacco leaf by using the heated air chamber with a vertical stove and old flue cured chamber, show that the property of the new type chamber is better than that of the old chamber, which is of decreasing fresh/dry weight ratio of baked tobacco leaf, increasing single leaf weight, improving superior tobacco leaf (8.05%~15.39%) and reducing coal consumption (0.59~0.78kg/baked tobacco leaf). There are no difference between treatment 1 and 2.
