本文在大量地实测了烟囱日照温度的基础上,应用统计方法,对实测温度进行了回归分析,揭示出日照温度沿烟囱筒体高度、环向及随时间的分布规律;应用热传导理论,推导出非稳态温度(日照温度)沿烟囱筒体径向的分布规律。最后建立了烟囱筒体日照温度场的数学表达式。 In this paper, on the basis of a large number of measurements of the sunlight temperature of the chimney, a statistical method was used to perform a regression analysis of the measured temperature, revealing the distribution law of the sunlight temperature along the chimney height, the hoop direction and the time; applying the heat conduction theory, deducing The distribution of non-steady-state temperature (solar temperature) along the chimney tube radial direction. Finally, the mathematical expression of the sunlight temperature field of the chimney shell was established.
