Abstract (en)
[origin: EP3584499A1] The present disclosure relates to a distributor and a burner and a water heater having the same. The distributor includes at least three injection pipes, a gas mixing cavity, a splitter and a first through hole. Each injection pipe is provided with a flow guiding inclined surface, and the flow guiding inclined surface is formed by inclining an end surface of a gas outlet section of the injection pipe to two sides. The gas mixing cavity is communicated with each injection pipe. The splitter is disposed at the gas outlet section of the injection pipe and recessed to an interior of the gas mixing cavity to split gas to two sides. The first through hole is disposed beside the injection pipe for the cooling water pipe to pass through and is in close contact with the cooling water pipe. The present disclosure can increase the ejector coefficient, make the gas combustion more complete, and reduce generation of nitrogen oxides.
