通过冷态模拟试验，研究了多火孔无焰陶瓷燃烧器的阻尼特性、喷口流体的均匀性、燃烧室以及扩张段的流场特性, 开发和设计了一种顶燃式热风炉用多火孔无焰陶瓷燃烧器，实践表明，在单烧高炉煤气的情况下，使用该燃烧器的热风炉可稳定提供1200 ℃风温，热效率达到78.95％,节能效果明显。

A Multiport annular flameless ceramic burner for hot blast stove is introduced. The damp characteristics uniformity of fluid field at port,flow patterns in the chamber and expansion section were studied by cold model experiment. This ceramic burner was used on No.6 blast furnace at Liuzhou Iron & Steel Corporation Ltd. It was proved that this ceramic burner could be used on hot blast stove for higher efficiency and heating blast to 1200 ℃.
