摘 要：烟叶烘烤过程中，装烟室大量的高温湿气随气流交换被排放到密集烤房之外，造成热量的大量流失。基于空气源热泵热量转运的特点，在原有生物质燃料供热设备的基础上，添加一套空气源热泵余热回收装置，在烟叶烘烤原有生物质燃料供热方式下进行辅助供热。结果表明：双制式烤烟供热系统烘烤下部叶干烟成本降低18.1%;烘烤中部叶干烟成本降低22.9%;烘烤上部叶干烟成本降低19%，节能效果明显。本设备每年使用成本为500元，每年可节约烘烤成本1 470元。该系统在不改变原有烘烤工艺的基础上实现了烤房余热回收，对于多途径丰富烤烟供热的方式具有参考意义。

Abstract： In the process of tobacco leaf curing， a large amount of high temperature moisture in the tobacco leaf loading chamber was discharged out of the bulk curing barn with the exchange of airflow， resulting in a large amount of heat loss. Based on the characteristics of heat transfer with the air source heat pump， a set of waste heat recovery device of air source heat pump was added on the basis of the original biomass fuel heating equipment， and then the auxiliary heating was carried out under the heating mode of curing the original biomass fuel with tobacco leaves. The results showed that by using the double-system flue-cured tobacco heating supply system， the cost of curing the lower leaf dry tobacco was reduced by 18.1%， and the cost of curing the middle leaf dry tobacco was reduced by 22.9%， while the cost of curing the upper leaf dry tobacco was reduced by 19%， showing obvious energy-saving effect. The usage cost of this equipment was 500 yuan per year， and the cost of curing could be saved 1 470 yuan per year. The system realized the waste heat recovery of the curing barn without changing the original curing technology， which had reference significance to enrich the heat supply of flue-cured tobacco in multiple ways.

煙叶烘烤是烤烟生产的重要环节。密集烤房有装烟量大，温湿度控制自动化程度高的特点，是当前国内烟叶烘烤使用的主要烤房类型。国内大部分的密集烤房是按照国烟办综（2009）418号文件的技术规范建造的[1]。目前，我国密集式烤房仍以煤炭为主要燃料，生物质燃料、空气源热泵、天然气等能源为辅[2]。

近年来，随着新能源产业的发展，国内对新能源密集烤房也开展了广泛的研究[3-5]。研究表明[6-9]，在烟叶烘烤成本上，空气源热泵烤房<生物质燃料烤房<燃煤烤房，并初步形成了空气源热泵和生物质燃料替代燃煤的趋势。在烤后烟叶质量上，热泵烤房烘烤的烟叶颜色鲜亮、成熟度好、组织结构疏松，内在品质有所改善，上等烟及产值均有所提高[10]。……
