    • The object is to provide a burner capable of taking in sufficient primary air even though the size thereof is compact, and capable of being properly used as an all-primary air burner.
      A burner 1 includes a mixing pipe 4 to which a fuel gas and air for combustion are supplied, a burner main body 2 having a mixing chamber 6 at a top end on a downstream side of the mixing pipe 4, and a burner head 3 which is provided at an upper part of the burner main body 2 while communicating with the mixing chamber 6 and has first and second burner ports 15 and 16 for jetting mixed gas of the fuel gas and combustion air mixed in the mixing chamber 6. The burner further includes an extension pipe 8 in the burner main body 2 protruding inside the mixing chamber 6 being formed by extending of the mixing pipe 4.
    • 本发明的目的是提供即使其尺寸紧凑也能够获得充足的一次空气并且能够适当地用作全空气一次燃烧器的燃烧器。 燃烧器1包括供应燃料气体和用于燃烧的空气的混合管4,在混合管4的下游侧的顶端处具有混合室6的燃烧器主体2以及燃烧器头3 在与混合室6连通的同时设置在燃烧器主体2的上部,并具有用于喷射在混合室6中混合的燃料气体和燃烧空气的混合气体的第一和第二燃烧器口15和16。 在混合室6内突出的燃烧器主体2的延长管8通过混合管4的延长而形成。
