中文拼音 [tànqīngyǎngbǐlì]
碳氫氧比例
英文
c-h-o ratio-
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Quality problem is a significant strategy problem. quality management in work site is the important link of the overall quality managment. the paper summarizes the missions of quality management in situ in four aspects, i. e. the prevention of quality defects, control of quality working procedure. improvement of quality, inspection and evaluation of quality. the specific requirements and implement measures for quality management which should be performed strictly by managing staff, technicians and workers are also proposed in this paper
乙醇,俗稱酒精.乙醇汽油是一種由糧食及各種植物纖維加工而成的燃料乙醇和普通汽油按一定比例混配的替代能源.按照現行國家標準,乙醇汽油是用90 ?的普通汽油與10 ?的燃料乙醇調合而成,它可有效地改善油品的性能和質量,降低一氧化碳、碳氫化合物、氮氧化物等主要污染物的排放,有著巨大的環保效應,而且它對機動車的行駛性能也沒有影響
