This paper analyses the four problems about the regenerator, air and gas orifice, ignition unit and switching style in practical application of regenerative combustion technology. 分析了蓄热式燃烧技术应用中蓄热体设计、空气和煤气喷口设计、点火装置设计和换向方式设计4个实际问题。
The diameter of the gas orifice has a great influence on the flame length, and the position of the top gas orifice and the cone angle of the burner tile have a little effect on the flame length. 燃气喷孔直径对火焰长度的影响非常显著,喷头顶部气孔位置和火盆锥口角对火焰长度影响较小。
