چکیده
پژوهش حاضر، شبیه‌سازی CFD یک کورۀ صنعتی شرکت پتروشیمی شهید تندگویان (STPC) است که به‌منظور تحلیل شرایط بهره‌برداری بر تغییرات خواص حرارتی روغن و پدیده‌های انتقال حرارت در کوره‌ و داکت توزیع آن دارای 8 گذرگاه انجام‌شده‌است. وجود بیشتر ذرات کک در برخی گذرگاه‌ها بنابر سابقۀ تجربی کوره، گرفتگی آن‌ها را در پی‌ داشته که بنابر نتایج شبیه‌سازی، هندسۀ داکت ورودی روغن در آن، مؤثر بوده‌است. این داکت، توزیع متفاوتی از جریان و ذرات کک را در 8 گذرگاه موازی کوره ایجاد کرده که به‌جز توزیع بیشتر ذرات کک در برخی آن‌ها، موجب زمان ماند متفاوت روغن در گذرگاه‌ها شده‌است. شبیه‌سازی احتراق در کوره نیز نشان‌داد که نقاط داغ در نواحی کوره به‌خصوص در خروج گازهای احتراق از ناحیۀ تشعشع به ناحیۀ همرفت ایجادشده‌است که می‌تواند دلیل دیگری برای تخریب روغن باشد. هم‌چنین، مطابق نتایج شبیه‌سازی، با کاهش 3/6 کیلوگرم بر ثانیه در دبی یک گذرگاه روغن، دمای خروجی آن گذرگاه در بخش تشعشع، 1/1 درجۀ سلسیوس افزایش‌یافت.

چکیده English

The present research is CFD simulation of industrial furnace related to Shahid Tondgouyan Petrochemical Company (STPC) to analyze the impact of operating conditions on thermal properties changes of oil and heat transfer phenomenon in the furnace and its distribution manifold with 8 passes. According to the experimental history of the furnace, the presence of more coke particles in some passes has led to their clogging, which according to the simulation results, the geometry of the oil inlet manifold in it has been effective. This manifold has created a different distribution of flow and coke particles in the 8 parallel passes of the furnace, which, in addition to the greater distribution of coke particles in some of them, has caused different oil residence times in the passes. The combustion simulation in the furnace also showed that hot spots have been created in the furnace areas, especially in the exit of combustion gases from the radiation zone to the convection zone, which could be another reason for the destruction of the oil. Also, according to the simulation results, with a decrease of 3.6 kg/s in the flow rate of an oil pass, the outlet temperature of that pass in the radiation section increased by 1.1 degrees Celsius.
