摘要
吸烟与多种疾病相关,卷烟燃吸中烟气化学成分主要来源于烟丝的不完全燃烧和热解,深入理解卷烟燃吸中热物理条件对烟气有害成分的释放水平是非常重要的,许多研究者通过调控卷烟燃烧状态降低危害性化学成分的释放。点燃卷烟在未抽吸时为静燃状态,抽吸过程中,气流迅速改变了卷烟内部气相与固相温度。在此过程中,燃烧锥内部形成两个独立区域——燃烧和热解区,燃烧锥温度动态变化是分析卷烟燃烧内部热物理和热化学的重要参数。因此,深入理解卷烟燃烧状态有助于调控卷烟烟气化学成分释放水平。本论文研究了标准抽吸和加拿大抽吸模式下卷烟燃烧锥气相温度场分布。测量不同温度范围内燃烧锥体积动态分布和不同体积百分数分布计算,获得温度和温度梯度的二维图,并依据温度及温度梯度特征,讨论了燃烧过程中的热解、燃烧区域分布的可能性,并对比分析烟丝在两种抽吸模式下的瞬态变化特征,为研究卷烟烟气前驱体释放之间的关系和烟用添加剂热解过程提供理论参考。
Cigarette smoking is associated with a number of fatal diseases. Chemical emissions from a burning cigarette are mainly produced from incomplete combustion and pyrolysis of tobacco. Understanding the thermal conditions inside a burning cigarette is important in controlling emission levels. This study examined gas-phase temperatures of a burning cigarette coal under the International Organization for Standardization(ISO) and the Health Canada intensive(HCI) smoking conditions. The dynamic distributions of coal volumes associated with different temperature ranges were measured and a mathematical equation was used to model the distributions of different volume fractions. 2-D temperature and temperature gradient contours were constructed and compared to highlight the heterogeneous heating of cut tobacco under two different smoking regimens. The information may be useful to guide analytical pyrolysis studies aimed at assessing precursor-smoke emission relationships and the fate of tobacco ingredients added to cigarettes.
