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 massive over - fishing of the largest predatory sharks in the coastal waters of the atlantic over the past 30 - some years has led to an explosion in the ray, skate and small shark species that they prey on, with devastating effects for one of the organisms at the bottom of the food chain
