Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
文摘:應用計算機模擬的方法，在不考慮燃燒的冷態情況下，研究了熱風爐燃燒室內的氣流分佈規律.在此基礎上，比較了2種不同設計方案的氣流流動特徵，尤其是研究了燃燒器空氣通道內阻流板的設置與否對空氣和煤氣的流動和混合的影響.結果表明，阻流板的設計對加強空氣和煤氣的混合有著極為重要的作用，同時也增加了空氣管道的阻力損失，在同樣的工況條件下需要提高管道系統的總壓力Analysis of experimental data indicates that there exist several following problems during the whole operation : first, the emission is serious and the density of hc and co smoke is very high at on and off period. second, there is oil dripping from the dripping vitta as a result of the fault of ignition system and combustion structure. the last, there might be accidents of disabled ignition resulted from the improper operation at the beginning
通過對樣機的試驗分析和研究表明，汽車空氣燃油加熱器在整個工作過程中，其排放存在以下三個問題：一、開機和關機兩個階段的排放問題嚴重，廢氣中hc和co的濃度值及煙度測量值都很高；二、因點火系統和燃燒結構的缺陷而導致開機后一段時間內有油滴從滴油管滴落；三、在點火過程中，會出現因操作不當而點火失效的現象。Based on the coal burning mechanism in the precalcinator, by analysing all kinds of effect factors and according to the tga result of the anthracite, sinoma international ncdri developed the on - line spout pipe calciner for 5000 t / d production line of china resource cement ( guigang ) ltd., which composed an excellent - performance precalcining system combined with high - efficiency low - resistance and blockingproof cyclone preheater
基於分解爐煤粉燃燒機理，並通過分析影響爐內煤粉燃燒的各種因素及依據所用無煙煤的熱失重分析結果，中材國際南京水泥設計研究院開發設計出了用於華潤貴港5000t / d工程的噴旋管道式在線分解爐，並與高效、低阻、防堵的旋風預熱系統組成了性能優異的預分解系統。Mean while, the iouver concentrator structure principle is analyzed, the iouver puiverized coal concentrator is studied on the bases of both laboratory and production. lt is discovered from the experiments that the louver horizontai rich / lean combustion pulverized coal burner has advantages of simple in structure, low resistance and adjustment of pc concentration
同時，重點分析了百葉窗濃縮器的結構原理，並在試驗臺上和現場對百葉窗煤粉濃縮器進行了大量的試驗研究，結果表明：百葉窗式水平濃淡煤粉燃燒器具有結構簡單、阻力損失小、分離調節方便等一系列優點。This paper has analyzed and synthesized the problems of burning heavy viscosity petroleum about injecting steam boilers in liaohe oil field. the heat balance experiments on injecting steam boilers burning heavy viscosity petroleum is made first. the main causes of low thermal efficiency and heat lose of flue gas are the poor effect of atomization and burning with old - fashioned oil nozzles, worse ash gathered on. heat exchange surface and high temperature of flue gas
本論文在分析綜述了遼河油田注汽鍋爐燃用高粘度稠油時存在的問題的基礎上，首先對燃用稠油的注汽鍋爐進行了正、反熱平衡試驗，分析了注汽爐熱效率偏低、排煙熱損失偏高的主要原因是原噴油嘴改燒高粘度稠油時霧化和燃燒效果差、換熱面積灰嚴重、排煙溫度太高。The research indicated that, if the secondary combustion chamber was looked on as a controlled object, with the adjusting valve as a input, the pressure and the temperature of a selected point on the inside wall of the combustion chamber as outputs, then such controlled system would be a strongly non - linear, time varying system with number of random disturbances, which resulted in huge difficulty to build an analyzed mathematics model for the spray burning of the liquid fuel, so that classic control methods were all invalid
研究表明，若將rbcc發動機的二次燃燒室視為一個控制對象，同時以燃燒室內壁面取定點處的壓強、溫度和調節閥的開度為輸入輸出變量，則該系統將是輸入?輸出特性非線性很強、隨機干擾嚴重的復雜時變系統。這導致建立燃油噴霧燃燒具體模型的很大困難，從而宣告了經典控制方案的失效。Heat efficiency of power station boiler is an important research subject in which carbon loss is an important parameter to reflect combustion performance of boiler, however, there is no favorable means to estimate it definitely
電站鍋爐熱效率的研究是一個重要的課題。其中，機械未完全燃燒熱損失是反映鍋爐燃燒工況好壞的一個重要指標，目前卻缺乏非常有利的工具和手段來明確判斷。The combustion chamber outer casing and bearing chock are important parts of aero - engine. the fatigue failure of them is the most concerning problem in engineering. then, in this paper the strength and fatigue life of the outer casing and bearing chock including welding line have been analyzed
