冶金部钢铁研究总院与攀钢在消化引进国外设备技术的基础上,结合国情,设计了一种新型高炉炉顶点火器(电动单梁燃烧器插入式),并在攀钢2号高炉上使用。一般每次点火过程仅需15min(人工点火过程需耗时50～60min),做到了迅速、安全、可靠。该高炉炉顶点火器主要由燃烧器、移动小车、小车轨道、驱动装置、气控系统、电气控制系统、引火器等组成。燃烧器采用有焰燃烧技术,设计为套筒式焊接结构,使煤气与空气平行流动,离开烧嘴才开始混合,以利放慢混合速度,拉长火焰,并降低所需空气压力。另一方面,考虑到有焰燃烧可能会出
On the basis of digesting the technology of foreign equipment and combining with the national conditions, a new type of blast furnace top igniter (electric single-beam combustor plug-in type) was designed and used on the No. 2 blast furnace of Panzhihua Iron and Steel . Generally only 15min each ignition process (artificial ignition process takes 50 ~ 60min), so that the rapid, safe and reliable. The blast furnace top igniter is mainly composed of a burner, a moving trolley, a trolley track, a driving device, a gas control system, an electric control system, a firearm and the like. Flame-fired burner technology, designed as a sleeve welded structure, the gas flowing parallel to the air, leaving the burner began mixing, in order to slow down the mixing speed, flame and reduce the required air pressure. On the other hand, considering flaming combustion may be out
