中文拼音 [tànhuàwùjiārèlú]
碳化物加熱爐
英文
carbide furnace-
An analysis made from theory to practice of the three major contradictions, viz., blow gas and gas generation, upward blow and downward blow and coke addition and slag discharge, and the three major equilibria, viz., material and carbon equilibrium, thermal equilibrium and chemical equilibrium existing in coal gasifiers
摘要從理論到實際剖析了煤氣爐內存在的吹風與制氣、上吹與下吹、加炭與排渣三大矛盾和物料與碳平衡、熱平衡、化學平衡三大平衡。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Abstract : a preliminary investigation was made on hearth damage of a number of furnaces in china, and the analysis and discussion are presented for reasons of hearth damage in this paper. the main reasons of ring crack of the hearth are : 1. improper physical and chemical properties of baked carbon bricks. 2. the thermal stress existing in carbon bricks, alumina bricks and the furnace shell. the formation of the ring crack aggravates the abnormal erosion of the hearth
文摘:結合鞍鋼2號和7號等高爐和2號高爐的調查結果，對國內部分高爐爐缸破損情況進行初步調查，對爐缸破損原因做了初步分析和討論，認為造成我國高爐爐缸環形斷裂的主要原因是由於碳磚自身物化性能差以及爐缸碳磚和高爐爐殼之間的熱應力；環裂的出現加劇了爐缸的異常侵蝕。
