摘要
为了研究卷烟纸助燃剂(柠檬酸钾)含量对烟支燃烧状态的影响,采用改变卷烟纸助燃剂含量与定量的方法制备试验卷烟样品,利用微细热电偶,对卷烟燃吸过程的温度变化进行检测,通过改进Rosin-Rammler(R-R)颗粒尺寸分布模型,建立了以燃烧锥体积V0、特征温度Ts和分布参数N为特征量的卷烟燃吸温度分布表征方法,并利用该方法考察了卷烟纸助燃剂含量和定量对卷烟燃吸温度分布特征(静燃、抽吸和阴燃)的影响。结果表明:①在整个卷烟燃吸过程中,燃烧锥最高温随卷烟纸助燃剂含量与定量的增加而降低;②随卷烟纸助燃剂含量和卷烟纸定量的增加,燃吸过程中各时刻点(静燃、抽吸及抽吸后阴燃)的燃烧锥体积呈增加趋势,并在抽吸结束后达到最大值;③静燃时,随卷烟纸助燃剂含量和定量的增加,燃烧锥特征温度Ts逐步增加,温度分布分散程度降低,而在抽吸时,特征温度Ts呈先增加后降低的趋势。
In order to study the influence of combustion improver （potassium citrate ） content in cigarette paper on cigarette burning state, the cigarette samples with cigarette paper of different grammages and containing different rates of combustion improver were prepared. The temperature in cigarette was detected with fine-thermocouples. By revising Rosin-Rammler （R-R） particle size distribution model, a method for characterizing temperature distribution in cigarette burning cone was developed, where, burning cone volume Vo, characteristic temperature T,, and distribution parameter N were taken as characteristic variables. The effects of combustion improver content and grammage of cigarette paper on temperature distribution characteristics in cigarette during static burning, puffing, and smouldering stages were investigated. The results showed that ： With the increase of combustion improver content and grammage of cigarette paper, 1） The highest temperature in burning cone decreased during the whole process of cigarette smoking. 2） The volume of burning cone increased in all of the three burning stages, and reached its maximum value at the end of a puffing. 3） The characteristic temperature Ts of burning cone raised gradually and the range of temperature distribution decreased during static burning; however during puffing, T, raised and then dropped.
