卷烟燃烧参数、灰分外观和烟气成分相互关系研究

Study on the relationship among cigarette combustion parameters,ash appearance and smoke components

【目的】揭示卷烟燃烧三个维度之间相互关系。【方法】利用统计分析方法研究了卷烟燃烧参数(燃烧温度、耗氧量和燃烧速率)、灰分外观指标(灰色值、裂口率、缩灰率、炭线宽度、炭线整齐度和持灰力)和烟气成分(烟气常规成分和七种有害成分)之间的相关性。【结果】(1)烟丝静燃速率、卷烟吸燃速率和耗氧量之间呈极显著正相关,但均与燃烧温度和卷烟纸阴燃速率无显著相关性;卷烟静燃速率仅与耗氧量显著正相关,燃烧温度仅与卷烟纸阴燃速率呈极显著负相关。(2)燃烧速率参数不仅与多种烟气成分显著负相关,亦与灰分外观质量显著正相关,与燃烧温度和耗氧量相比,是调节卷烟烟气和灰分外观质量更为有效的燃烧参数。

This study aims to reveal the relationship among cigarette combustion parameters(combustion temperature,oxygen consumption and combustion rate),ash appearance indexes(grey value,crack rate,ash shrinking rate,burning line width,burning line uniformity and ash holding capacity)and smoke components(conventional components and seven harmful components).The results showed that:(1)There was a very significant positive correlation among static burning rate of cut tobacco,cigarette smoking burning rate and oxygen consumption,but they had no significant correlations with combustion temperature and cigarette paper smoldering rate;cigarette static burning rate was only significantly positively correlated with oxygen consumption,and there was a very significant negative correlation between combustion temperature and cigarette paper smoldering rate.(2)The cigarette combustion rate,which had a significantly negative correlation with various smoke components and a significantly positive correlation with ash appearance quality,is a more effective combustion parameter to adjust the smoke components and ash appearance quality in comparison with combustion temperature and oxygen consumption.
