    • A lean-rich burner is provided, in which an air-rich flame and a fuel-rich flame are formed by a simple structure, thereby reducing the emission of noxious gas and enabling stable combustion. The lean-rich burner includes: a main flame part (110) for burning a fuel-rich mixture in which primary air, which is some of air supplied by a blower, and fuel are mixed; auxiliary flame parts (120) installed on left and right sides of the main flame part (110) to burn an air-rich mixture; a main mixture channel (130) for supplying the fuel-rich mixture to the main flame part (110); a mixture distribution hole (140) formed along the main mixture channel (130) to supply some of the mixture flowing along the main mixture channel (130) to the auxiliary flame parts (120); and a Venturi part (150) having a Venturi structure in which secondary air inflow holes (151) are formed to mix secondary air, which is some of the air supplied by the blower, with the mixture introduced through the mixture distribution hole (140).
    • 提供了一种富稀燃燃烧器,其中通过简单的结构形成富含空气的火焰和富燃料的火焰,从而减少有害气体的排放并实现稳定的燃烧。 富稀燃烧器包括:用于燃烧富燃料混合物的主火焰部分(110),其中混合由鼓风机供应的一些空气的一次空气和燃料; 辅助火焰部件(120)安装在主火焰部分(110)的左侧和右侧以燃烧富含空气的混合物; 用于将富燃料混合物供应到主火焰部分(110)的主混合物通道(130); 沿着主混合物通道(130)形成的混合物分配孔(140),以将沿着主混合物通道(130)流动的一些混合物供应到辅助火焰部分(120); 和具有文氏管结构的文氏管部分(150),其中形成有二次空气流入孔(151),以将由鼓风机供应的一些空气的二次空气与通过混合物分配孔(140)引入的混合物混合, 。
