摘要
在理论分析的基础上 ,设计了一种新型陶瓷燃烧器 ,并进行了冷态模型实验研究 ,实验结果表明 :( 1 )空、煤气通道联吹的阻力系数分别为 4 8～ 5 0和 1 8～ 2 0 ;( 2 )煤气通道的配气均匀度达到了 92 4 6 % ;( 3)一、二次风出口配气均匀度达到了 90 6 6 %和 94 57%。现场使用情况表明 ,本陶瓷燃烧器在纯烧高炉煤气的情况下 ,风温可稳定在 1 1 0
Based on the theoretical analysis,a new type ceramic burner is invented and the cold state model experiment is carried out.It is shown that the pressure loss factor of air and gas piping is 4\^8～5\^0 and 1\^8～2\^0;the homogeneous rate of gas piping system is 92\^46%;the homogeneous rate of the first and secondary air is 90\^66% and 94\^57%.The result of the field experiment proves that preheated air temperature achieves 1100℃ under the condition of burning blast furnace gas.
