摘要: 为探索辐射传热对中心加热卷烟温度分布和气溶胶释放的影响,在不锈钢外壳发热针表面涂覆硅氧烷涂层制备辐射传热型发热针,测定两种发热针的发射率,对两种发热针加热时烟支的温度场和实际温度进行模拟和测量,同时检测和分析加热过程中烟支的气溶胶释放情况。结果表明:硅氧烷涂层发热针和不锈钢外壳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,与不锈钢外壳发热针相比,硅氧烷涂层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;使用硅氧烷涂层发热针加热时,烟支气溶胶中总粒相物、烟碱和甘油释放量比不锈钢外壳发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,相关研究数据可为加热卷烟器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 pin was fabricated by coating a low-emissivity heating element with a silicone high-emissivity coating. The emissivity values of the high/low emissivity heating pins were measured, and simulations and measurements of the temperature distribution and actual temperatures at specific locations within the cigarette during heating with both types of pins were conducted. Additionally, the aerosol release from the tobacco rod during the heating process was examined. The results showed that the emissivity values of the high/low emissivity heating pins were 90% and 10% respectively. After heating for 200 s 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 pin was higher (154.1 ℃), with a smaller temperature difference from the heating element and a more uniform temperature distribution. When heated by the high-emissivity heating pin, 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 pin. In conclusion,high-emissivity heating pins utilizing radiative heat transfer plays a crucial role in enhancing the heating efficiency of centrally heated cigarettes, providing theoretical guidance and data support for the design and improvement of central heating tobacco devices.
