不同供热能源烤烟经济效益对比分析

为发展绿色烘烤,提高烤烟烘烤经济效益,选择当前烤烟供热新出现的生物质成型颗粒燃料、空气源热泵、燃气和醇基液体燃料清洁能源,通过2年间采集5个重点种烟省份8个大型烟叶烘烤工厂的烘烤数据,统计分析其各项经济效益指标。结合前人研究方法、收集现有报道的文献进行综合经济效益分析,结果显示,空气源热泵单炕的烘烤成本略高于燃煤,可作为烤烟供热最佳的后备热源;燃气和醇基燃料使用成本较高,当前不适合大面积推广;生物质成型颗粒燃料能够实现烟草废弃物的循环利用,是现阶段烟叶烘烤最佳的燃煤替代能源。

Economic Benefits of Different Heating Sources for Tobacco Curing: A Comparative Analysis

Applying clean energy heating for curing tobacco is the best way to realize greening tobacco production. To change the current situation of coal-fired heating for tobacco curing, the curing data of clean energy, including a biomass briquette fuel, air-source heating pump, gas fuel and alcohol-based fuel, collected from 8 large tobacco curing factories in 5 key tobacco-planting provinces for 2 years were analyzed comparing with coal combustion. And combined with the existing literature, the comprehensive economic benefits of different heating sources were studied. The results show that the curing cost of the air-source heating pump per batch each barn is slightly higher than that of coal-fired heating, which could be used as the best backup heating source for tobacco curing. And the gas fuel and alcohol-based fuel are not suitable for large-scale promotion at present because of their relatively high curing cost. The biomass pellet fuel could realize the recycling of tobacco wastes, which is the best alternative energy to coal fuel for tobacco curing at the present stage.
