【摘要】：油田加熱爐這一裝置在油田中轉(zhuǎn)站、聯(lián)合站中扮演著非常重要的角色。特別是類似于大慶油田這樣處在氣候比較寒冷地區(qū)的油田,其正常的生產(chǎn)需要用到更多、質(zhì)量更好的加熱爐。在過去很長一段時(shí)間內(nèi),人們主要通過工程計(jì)算、現(xiàn)場試驗(yàn)的方法,尋找性能表現(xiàn)更佳的加熱爐設(shè)備,這種方法的主要缺陷是人工、時(shí)間成本高。采用全新的數(shù)值方法,不但能夠提高研究效率,而且能夠使研究參數(shù)波動(dòng)范圍進(jìn)一步拓展,促進(jìn)研究的深入。本文通過數(shù)據(jù)模擬工具PHOENICS針對加熱爐爐膛中的燃?xì)馊紵归_數(shù)值模擬研究,針對加熱爐內(nèi)部不同部位的溫度進(jìn)行分析,創(chuàng)建燃燒、幅射換熱、對流換熱和熱流體流動(dòng)的模型;創(chuàng)建能夠反映出爐膛中各種變化的數(shù)學(xué)模型,應(yīng)用恰當(dāng)?shù)臄?shù)值模擬方法,監(jiān)測油田加熱爐試驗(yàn)臺并采集相關(guān)的數(shù)據(jù),根據(jù)這些數(shù)據(jù)繪制實(shí)際溫度、速度及壓力分布曲線圖,可由定性與定量兩個(gè)角度反映爐膛的實(shí)情。檢測結(jié)果和數(shù)值模擬情況展開對比,以便確定其是否精準(zhǔn)。結(jié)果顯示:加熱爐數(shù)值模擬結(jié)果和試驗(yàn)站測量結(jié)果基本吻合,計(jì)算模擬結(jié)果較為準(zhǔn)確。燃燒器1.5MW、爐膛直徑1m的條件下,20%、40%、60%、工況下爐膛過粗過長,80%工況時(shí)爐膛過長,加熱爐100%工況下,加熱爐殼體局部呈現(xiàn)太高的溫度,表現(xiàn)較大的熱應(yīng)力,極在可能產(chǎn)生燒窗事故。因此,要求縮短加熱爐長,增加直徑,在保障安全運(yùn)營的基礎(chǔ)下,達(dá)到降低耗鋼量的目的。
[Abstract]:The oil field heating furnace plays a very important role in the oil field transfer station and the combined station. Especially in the colder climate areas such as Yu Daqing oil field, its normal production needs more heating furnace with better quality. In the past a long time, people mainly through engineering calculation, field test method, to find better performance of heating furnace equipment, the main defect of this method is labor, high time cost. The new numerical method can not only improve the efficiency of the research, but also further expand the range of the fluctuation of the research parameters, and promote the further study. In this paper, the numerical simulation of gas combustion in furnace is carried out by the data simulation tool PHOENICS, and the models of combustion, radiation heat transfer, convection heat transfer and heat fluid flow are established by analyzing the temperature in different parts of the furnace. A mathematical model which can reflect all kinds of changes in the furnace is created, and the appropriate numerical simulation method is used to monitor the oil field heating furnace test-bed and collect the relevant data. According to these data, the curves of actual temperature, velocity and pressure distribution are plotted. The facts of furnace can be reflected from both qualitative and quantitative angles. The test results are compared with the numerical simulation to determine whether they are accurate or not. The results show that the numerical simulation results of the furnace are in good agreement with the measured results of the test station, and the simulation results are more accurate. When the burner is 1.5MW, the furnace diameter is 1m m, the temperature of the shell is too high, and the thermal stress is high, and the window burning accident is likely to occur under the condition that the furnace is 80% too thick and 80% too thick. Therefore, it is necessary to shorten the heating furnace length, increase the diameter, and achieve the purpose of reducing steel consumption on the basis of ensuring safe operation.
