采用陶瓷燃烧器已成为热风炉强化燃烧,提高风温的必不可少的手段。首钢从1974年开始,对陶瓷燃烧器的研究、设计和应用做了系统的工作,目前已在全公司的高炉上推广。1975年由首钢、北京钢铁设计院、武汉钢铁设计院以及清华大学组成的试验组,在实验室对陶瓷燃烧器进行了系统的冷态模拟试验。用模型比较了不同种类陶瓷燃烧器的阻力系数、出口火焰形状、火焰长度和气流速度分
The use of ceramic burners has become an indispensable means to enhance the combustion of hot blast stoves and increase the air temperature. Since 1974, Shougang has systematically worked on the research, design and application of ceramic burners and has now been promoting the company-wide blast furnace. In 1975 by Shougang, Beijing Iron and Steel Design Institute, Wuhan Iron and Steel Institute of Design and Tsinghua University, the experimental group of ceramic burners in the laboratory conducted a cold simulation test. The drag coefficient, outlet flame shape, flame length and air flow velocity of different kinds of ceramic burners were compared with the model
