摘要

本文研究了管式炉辐射传热

提出了焰墙黑度ε_gω新概念

从而导出了新的传热数学模型 q=4.96ε_0 F_c/(F_c)〔（T_g/100）~4-（T_c/100）~4〕+a_k（T_g-T_c）上述模型可以计算近代生产乙烯裂解管式炉。对于箱式加热管式炉和圆筒加热管式炉的传热计算

也提出了相应的数学模型。用本文提出的方法和另外两种通用的方法进行了6种裂解管式炉的计算。计算结果表明

此法计算简单

计算值与实际值符合得很好。

Abstract

The transmission of radiant heat in the tubular furnace has been studied. A new method of calculation is developed and a mathematical model is formulated. By means of this mathematical model

the heat of transmission for modern cracking tubular furnaces

heater of box type and cylindric heater can be solved more correctly. The new mathematical model for cracking tubular furnace is as follows.The mathematical model is derived from a new concept i. e. the flame-wall emissivity gw. Other types of mathematical models already in use are also discussed. As an example for illustration

six modern cracking tubular furnaces are calculated with the new method. The calculated and actual values are in agreement quite well. It is shown by these results that the proposed new model may be used in practical engineering calculations.
