摘要: 为探索辐射传热型加热针对中心加热卷烟温度分布和气溶胶释放的影响,在低发射率加热针表面涂覆硅氧烷涂层制备高发射率发热针,测定了高/ 低发射率发热针的发射率,对高/ 低发射率发热针加热时烟支的温度场和实际温度进行了模拟和测量,同时检测和分析了加热过程中烟支的气溶胶释放情况。 结果表明:高/ 低发射率发热针的发射率分别为 90%和 10%;采用相同温度曲线加热 200 s 后,与低发射率加热针相比,高发射率发热针加热的烟支内部平均温度更高(154. 1 ℃ ),且与加热元件的温差更小,温度分布更均匀;使用高发射率发热针加热时,烟支气溶胶中总粒相物、烟碱和甘油释放量比低发射率加热针加热时分别提升了42. 8%、17. 6%和 44. 5%。 综上,辐射传热型高发射率发热针对提高中心加热卷烟的加热效率具有重要作用,相关研究数据可为中心加热烟具的设计和改进提供理论指导和数据支撑。Abstract: To explore the impact of radiative heat transfer on the temperature distribution and aerosol release in centrally heated cigarettes, a high-emissivity heating element was fabricated by coating a low-emissivity heating elementwith a silicone high-emissivity coating. The emissivity values of the high / low emissivity heating elements were measured, and simulations and measurements of the temperature distribution and actual temperatures at specific locationswithin the cigarette during heating with both types of elements were conducted. Additionally, the aerosol releaseof the heating device during the heating process were examined. The results showed that the emissivity values of the high / low emissivity heating elements were 90% and 10% respectively. After heating for 200 seconds using the same temperature curve setup, compared to the low-emissivity heating element, the internal average temperature of the cigarette heated by the high-emissivity heating element was higher (154. 1 ℃ ), with a smaller temperature difference from the heating element and a more uniform temperature distribution. When heated by the high-emissivityheating element, the total particulate matter, nicotine, and glycerol release in the cigarette aerosol increased by 42. 8%, 17. 6%, and 44. 5% respectively, compared to those heated by the low-emissivity heating element. These findings confirm that radiative heat transfer plays a crucial role in enhancing the heating efficiency of centrally heatedcigarettes, providing theoretical guidance and data support for the design and improvement of central heating tobaccodevices.
