余热共享密集烤房的开发

Development of Bulk Curing-barn with Pooling Surplus Heat

摘要: 为合理利用烘烤过程中产生的余热，设计开发了新型余热共享密集烤房。其建造方法是：并排建造4 个装烟室，在各装烟室内靠近加热炉一侧，横向建造余热共享通道，每个烤烟室通道上方的中间位置设一个进（出）风口。对比试验结果表明，该新型烤房可提高热能利用率20%，烘烤成本降低0.57 元/kg，烤后橘黄烟叶比例提高，烟叶均价提高0.66 元/kg。

Abstract: In order to make reasonable use of the surplus heat in the course of tobacco curing, a new type bulk curing-barn was developed in this study. Four curing barn was built side by side and the chunnel pooling surplus heat was built crossly on the side near the furnace. In the middle location above the chunnel in each barn the heat gas inlet (or outlet) was set up. The results showed that the new type of barn could save 20% of heat source, reduce the cuing cost 0.57 yuan per kilogram tobacco leaves, enhance the proportion of orange leaves and the average price of the cured leaves increased by 0.66 yuan/kg.
