Abstract (en)
[origin: WO2019219037A1] A distributor (100), and a combustor (10) and a water heater having same, the distributor (100) comprising: a first housing (100A) and a second housing (100B) symmetrically provided; ejection tubes (110), each comprising the first housing (100A), the second housing (100B) and an inlet end (113), the ejection tubes (110) ejecting gas upward from the inlet ends (113); and pitch positioning structures (150) provided outside the ejection tubes (110), each pitch positioning structure comprising a first protrusion (151) and a second protrusion (152) provided symmetrically, the first protrusion (151) being formed by the portion of the first housing (100A) protruding toward the outside of the ejection tube (110), and the second protrusion (152) being formed by the portion of the second housing (100B) protruding toward the outside of the ejection tube (110), side walls of the inlet ends (113) of the two adjacent distributors (100) abutting, and the pitch positioning structures (150) of the two adjacent distributors (100) abutting. The combustor (10) can better secure the fixation between the distributors (100) and reduce shaking or vibration, thereby reducing the working noise of the combustor (10).
