Abstract

Abstract:

The tubular heating furnace is a key heating unit and a major energy consumer in refinery and chemical plants.Improving fuel combustion efficiency and the thermal efficiency of the heating furnace is of practical significance for energy conservation and emission reduction in these facilities. In this paper, the tubular heating furnace of aviation kerosene hydrofining unit is studied. The computational fluid dynamics (CFD) simulation method is adopted, and the standard k?ε turbulence model, component transport combustion model and P?1 radiation model are used. The temperature of the furnace, the average temperature of the surface of the furnace tube and the temperature distribution of the burner were investigated by changing the oxygen content of the combustion air. The results indicate that when the oxygen volume fraction changes in the range of 18.55%-26.00%, the oxygen volume fraction change has a significant impact on the temperature field and combustion efficiency in the furnace, and the existing radiation chamber, furnace tube and burner fully meet the needs of oxygen?rich combustion..

Key words: Tubular heating furnace, Radiant chamber temperature, Oxygen?enriched combustion, CFD simulation, Oxygen volume fraction

摘要：

管式加热炉是炼油化工装置的关键供热单元和能耗大户。改善燃料的燃烧效果，提高加热炉的热效率，对炼油化工装置的节能减排具有一定的现实意义。以航空煤油加氢精制装置的管式加热炉为研究对象，采用计算流体动力学（CFD）模拟方法，基于标准k?ε湍流模型、组分输运燃烧模型以及P?1辐射模型，通过改变助燃空气中氧体积分数，分析了氧体积分数对现有加热炉的辐射室温度、炉管表面平均温度以及燃烧器炉嘴温度分布的影响。结果表明，当氧体积分数在18.55%～26.00%的范围内变化时，氧体积分数对炉内温度场和燃烧效率有显著影响，现有的加热炉辐射室、炉管和火嘴能完全满足富氧燃烧的需要。
