Abstract : during the heating of scrap with carbon or hydrocarbon contented substances in some process, it will bring problems like explosion of carbon monoxide, fume and smell from oil volatilization, etc. ， if incomplete combustion occurs. through laboratory experiments, the time related variation of gas contents and post combustion ratio of fume during the heating of oil - bearing scrap are studied. the results show that the restrictive chain of reaction procedure is the thermolysis of oil ; that temperature and ( co ) / ( co2 ) ratio influence transformation ratio and post - combustion ratio under lower temperature ; that 900 is the temperature above which the complete reaction can be ensured at all ( co ) / ( co2 ) ratios
文摘:在某些廢鋼熔煉過程中，當爐料中含碳及碳氫物質且燃燒不充分時，會帶來煙氣中一氧化碳的燃爆、油污揮發時造成的煙霧、臭味等問題.通過實驗室裝置研究含油廢鋼在加熱過程中煙氣成分隨時間的改變以及二次燃燒率的變化，試驗結果表明，反應過程的限制性環節是油分的熱分解；在較低的溫度下（ co ） / （ co2 ）比例影響轉化率和二次燃燒率；而在任意比例下保證充分反應的溫度為900以上The convective term is solved by ausm + ( a sequel to ausm which means " the advection upstream splitting method " ). the 7 species 8 steps model and 7 species 7 steps model of hydrogen / air is used in the hydrogen reacting flowfield, the 9 species 5 steps model of methane, the 10 species 10 steps model of ethane and the 10 species 13 steps model of kerosene are used in the hydrocarbon reacting flowfield, the results of the distributions of velocity, mach number, pressure, static temperature, total temperature, species mass fraction and the combustion efficiency are gained, and the numerical results of the pressure of hydrogen and methane are compared with those of the experiment
計算中通量項採用ausm +通量分裂格式，氫反應流場採用氫/空氣的七組元八方程模型和七組元七方程模型，碳氫反應流場採用甲烷的九組元五方程模型、乙烯的十組元十方程模型和煤油的十組元十三方程模型，得出了超燃發動機燃燒室流場的速度、馬赫數、壓力、靜溫、總溫和組元質量分數分佈及燃燒效率等性能參數，其中氫和甲烷的計算壓力分佈與實驗結果進行了比較。H c fuel hydrogen carbon ratio
