[0004] In fact, the inventor found in the research that if the flue gas is directly sent to the burner for combustion (that is, the gas and the flue gas are not fully mixed and sent to the burner), not only will the burner burn unstable, but also cannot effectively burn. Reduce harmful gas emissions

Embodiment Construction
[0049] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0050] The inventors have found in multiple combustion tests that the mixture of gas, combustion-supporting air and flue gas can be burned in a flameless manner, and compared with flaming combustion, the harmful gases emitted by flameless combustion are greatly reduced.
[0051] The inventors further found that the degree of mixing of gas and flue gas is related to the amount of harmful gas emitted from the flue gas, and the more uniform the mixing of gas and flue gas, the less the amount of harmful gas emitted.

The invention discloses a burner and a gas water heater. The burner comprises a plurality of burning units connected in sequence, a burning face plate, and a smoke distributor, wherein each burning unit comprises a mixing cavity and a burning cavity which are interconnected; the burning cavity is located above the mixing cavity; the burning face plate is located above the burning cavity; a plurality of fire outlets are formed in the burning face plate; and the smoke distributor is used for conveying the gas mixture of gas and smoke to each burning unit. According to the burner of the embodiment, before the gas and smoke enter the burning units, the gas and smoke are mixed in the smoke distributor in advance, and then are sent to the burning units for burning, thus, the burning stability ofthe burner is ensured, and the emission of harmful gases is reduced.
Description
technical field [0001] The present invention relates to the technical field of water heaters, more specifically, to a burner and a gas water heater. Background technique [0002] During the combustion process of gas water heaters, harmful gases such as CO and NOx will be emitted to the outside world, which not only pollutes the environment but also easily brings danger to personal safety. [0003] Patent No. 201710314570.1 discloses a high-efficiency flue gas circulation system. In this patent document, the flue gas is directly sent into the burner for secondary combustion, the purpose of which is to reduce the emission of harmful gases. [0004] In fact, the inventor found in the research that if the flue gas is directly sent to the burner for combustion (that is, the gas and the flue gas are not fully mixed and sent to the burner), not only will the burner burn unstable, but also cannot effectively burn. Reduce harmful gas emissions. Contents of the invention [0005] ...
