摘　　要：热辐射强度计算对于高架火炬设计有着重要的指导意义,它是周边装置安全距离及火炬高度设置的重要参考。为了研究热辐射模拟计算在高架火炬升级改造中的应用,以某厂绿色转型发展项目的高架火炬改造工程为例,基于Flaresim软件,计算分析了实际项目中两套高架火炬火焰、热辐射及温度的相互影响,以指导高架火炬的完善设计。结果表明:新建火炬设计量排放对原有火炬无影响,无需对原有火炬改造。而原有火炬设计量排放对新建火炬影响较大,新建火炬塔架顶部20m需进行材质升级或设置防火措施,同时新建火炬应设计为可拆卸式,方便检修。Flaresim软件可为高架火炬升级改造及检修提供指导依据。The calculation of thermal radiation intensity is of great guiding significance for the design of elevated flares,and it is an important reference for the safety distance of surrounding devices and flare height setting.In order to study the application of thermal radiation simulation calculations in the upgrading and transformation of elevated torches,taking the elevated flare reconstruction project of a green transformation and development project of a factory as an example,based on Flaresim software,the flame,thermal radiation,and temperature interactions between the two sets of elevated flares in a real project are calculated and analyzed to guide the refined design of the elevated flares.The results show that the design emission of the new flare has no impact on the original flare,and there is no need to renovate the original flare.However,the design emission of the original flare has a greater influence on the new flare.The top twenty meters of the new flare tower need to be upgraded or set up with fire protection measures,and the new flare should be designed to be detachable to facilitate maintenance.Therefore,the Flaresim software can provide a basis for upgrading and maintaining the overhead flares system.
