煤氧枪是同时喷吹煤粉和氧气的一种新型燃料氧枪。目前国外已普遍使用燃料氧枪(主要为燃油氧枪)强化电炉冶炼,取得了降低电耗、缩短冶炼时间的显著效果。从我国能源状况出发,采用煤氧枪以强化电炉冶炼,对我国电炉的技术改造,将具有重大的现实意义。 采用水冷,内装旋流装置的煤氧枪,可使煤粉和氧气流出后具有一定的旋流强度,有利于点火和稳定燃烧。煤氧枪对准“冷区”,以一定倾角安装在电炉墙上。 从1982年12月起,北京钢铁学院在试验室着手进行了煤氧枪技术的开发,1985年4月1日已申请专利(专利申请号为85100842)。1985年6～8月,唐山钢铁公司与北京
Coal Oxygen Lance is a new fuel oxygen lance that injects pulverized coal and oxygen simultaneously. At present, foreign countries have widely used fuel oxygen lances (mainly fuel oxygen lances) to strengthen electric furnace smelting and achieved notable effects of reducing electricity consumption and shortening the smelting time. Starting from China’s energy situation, the use of coal-oxygen lance to strengthen the smelting furnace, the technical transformation of our electric furnace, will have great practical significance. The use of water-cooled, built-in rotary device coal oxygen lance, pulverized coal and oxygen can flow out of a certain degree of intensity, is conducive to ignition and combustion stability. Coal Oxygen gun aimed at the “cold zone” to a certain angle mounted on the furnace wall. From December 1982 onwards, Beijing Institute of Iron and Steel in the laboratory started the development of coal gas lance technology, April 1, 1985 has been patented (patent application No. 85100842). June ~ August 1985, Tangshan Iron and Steel Company and Beijing
