The invention discloses a combustor for a gas water heater. The combustor comprises a plurality of flame rows and a gas pipeline, wherein each group of flame rows mainly comprise a plurality of flame hole groups; each flame hole group comprises a plurality of flame holes; two outer sides of the flame hole group of each flame row are respectively provided with a lateral plate respectively, and gaps are reserved between the two outer sides of the flame hole group and lateral plates; the gaps are only communicated with the outside at the end openings of the lateral plates and the flame holes, and are sealed on the other parts; the gas pipeline comprises a light flame gas pipeline and a thick flame gas pipeline; the light flame gas pipeline is communicated with the flame holes hermetically; and the thick flame gas pipeline is communicated with the gaps between the lateral plates and the outer sides of the flame holes hermetically. The combustor has a simple structure, the discharge of nitrogen oxides can be controlled by thick and light combustion, and flame also can be transferred to the integral flame rows quickly to solve the problem of ignition deflagration due to slower flame transfer in the conventional flame rows effectively.
Description
technical field [0001] The invention relates to a burner, in particular to a burner for a gas water heater. Background technique [0002] The policy of energy saving and emission reduction has gradually deepened, and the state strongly advocates consumers to use gas water heaters. How to improve the comfort of gas water heaters and reduce the emission of nitrogen oxides is the main direction of the development of water heaters. [0003] The water heaters currently on the market often fail to transmit the flame in time and ignite the rest of the fire row when ignited, resulting in an increase in gas in the combustion chamber, which is likely to cause ignition and deflagration, which is extremely harmful. Contents of the invention [0004] In order to overcome the above-mentioned defects, the present invention provides a burner for gas water heaters, which can control the emission of nitrogen oxides within 50ppm by using thick-lean combustion to meet the requirements of the ...
