摘要:

基于耗散极值原理,综合考虑高温烟气和高温固体壁面间的辐射对流耦合传热过程,推导出适用于伴有参与性介质的等温漫射灰体开口系统传热分析的平衡方程,并验证该方程的正确性,拓展了理论应用范围.将该方程应用于现代燃烧单元结构分析,通过Matlab软件编程,理论计算得到再辐射壁面开口宽度、燃烧筒到烟气出口垂直距离、炉灶开口宽度等参数对热效率、锅底和燃烧筒传热量、再辐射壁面温度的影响规律,指出炉灶开口宽度是影响现代燃烧单元传热性能的关键结构参数.

Abstract:

The entransy balance equation on isothermal diffused gray body opening system with participating mediums was obtained based on the extremum entransy dissipation principle (EEDP) and coupled heat transfer of radiation and convection between high temperature gas and solid surface. The validity of the equation was proved and the application field of entransy theory was expanded. For the structural analysis of modern burning unit, some parameters’ (reradiation surface opening width, vertical distance between burning tube and gas outlet and stove opening width) influencing laws on thermal efficiency, heat transfer quantity of pan and burning tube and reradiation surface temperature were obtained by theoretical calculation with application of the equation through the software Matlab. The stove opening width was the key structural parameter of affecting heat transfer performance of modern burning unit.
