Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1 to Figure 3 As shown, the burner for a gas water heater includes at least one fire row communicated with the injector 1 . The structure of the ejector 1 can be selected from any one of the prior art as required.

[0021] Fire steak includes:

[0022] The mixing chamber 2 is a closed structure, and its inlet is connected with the outlet of the ejector 1, and is used for uniform flow and primary mixing of the premixed gas and primary air mixture sent from the ejector 1; A plurality of air outlet holes 21 are arranged at intervals on the side wall of the uniform chamber 2 .

[0023] The sleeve 3 is sleeved outside the mixing chamber 2, and the space between the side wall of the sleeve 3 and the mixing chamber 2 forms a remixing chamber 31 for premixing the introduced secondary air and primary mixed gas current sharing...

Abstract

The invention relates to a combustor used for a gas water heater. The combustor comprises flame tunnels communicating with an ejector. The combustor is characterized in that each flame tunnel comprises a blending chamber communicating with the ejector, and multiple gas outlet holes are formed in the side wall of the blending chamber at intervals; the blending chamber is sleeved with a sleeve; a once-again gas mixing cavity is formed by the space between the sleeve and the blending chamber; a flame plate is arranged on an outlet of the sleeve, and multiple flame holes are formed in the flame plate at intervals; a diversion plate is further arranged on the portion, between the blending chamber and the flame plate, in the sleeve; and the space between the blending chamber and the flame plate is divided into a diversion cavity and a blending cavity by the diversion plate, the diversion cavity and the blending cavity communicate with each other, and the blending cavity communicates with all the flame holes. By means of the combustor, secondary air can be supplemented multiple times, meanwhile, mixed gas is subjected to blending multiple times, it is ensured that gas is sufficiently combusted, the combustion efficiency of the gas is improved, NOx is effectively reduced, and the combustor is environment-friendly.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a burner for a gas water heater. Background technique [0002] Existing gas-fired water heaters are all ordinary row-shaped burners. Usually, when these burners are working, the combustion temperature is very high, and the combustion is often insufficient. During the combustion process, more CO and NOx are produced, which is very harmful to the human body. gas. With the advent of the world's energy crisis and the improvement of people's awareness of environmental protection, there are higher and higher requirements for the efficiency and emission of gas appliances, and the current burners that can achieve low NOx combustion are almost all using premixed combustion. The technology of similar burners is difficult and the cost is also high. [0003] CN201620116980.6 discloses a "gas water heater and its thick-thin burner". Two thick flame flow channels are formed between the outer pl...
