几种燃烧器的试验研究

介绍了武钢自1994年以来对几种常用燃烧器(烧嘴)的试验研究情况，分析了烧嘴在设计和应用中应当关注的一些问题，最后提出有关烧嘴试验研究的几点看法。     

高速烧嘴退火炉炉温均匀性数值研究

利用数值模拟技术,对一座采用高速烧嘴的台车式退火炉的炉温均匀性进行了数学模型实验.研究得出的模型适合退火炉的设计分析,并表明合理选择烧嘴尺寸和数量可以有效解决炉温均匀性、减少投资,达到优化设计的目的.     

Effectiveness of using oxygen-gas burners in modern arc steelmaking furnaces

Oxygen-gas burners have become a standard component of modern electric-arc steelmaking furnaces worldwide as a means of increasing productivity and reducing electric power consumption. The use of such burners in these furnaces is expedient from both an economic and an energy standpoint. On the average, the use of 1 m³ of natural gas to heat the scrap in the furnace charge saves 0.6–0.8 m³ of natural gas for the refining operation. The amount of heat obtained from the combustion of natural gas can be increased significantly by equipping arc steelmaking furnaces with high-capacity rotary oxygen-gas burners that allow changes to be made to the direction of the flame.
