Embodiment 1

[0032] Such as Figure 3-4 As shown, a positive pressure combustion low NOx burner, the burner includes a light gas introduction flow channel and a rich gas introduction flow channel, and the light gas introduction flow channel includes a light fire hole gas injection port connected in sequence 1. Light fire hole gas mixing chamber 3, light fire hole gas static pressure chamber 7 and fire hole assembly;

[0033] The described rich gas introduction circulation channel comprises the thick fire hole gas injection port 2, the thick fire hole gas mixing chamber 4 and the thick fire port gas balance chamber 5 connected in sequence, and also includes the thick fire hole gas coaming plate 8, the thick fire hole The gas coaming plate 8 surrounds the periphery of the fire hole assembly, and forms a thick fire hole gas outlet 21 between the fire hole assembly, and the thick fire hole gas outlet 21 is located on both sides of the semicircular fire hole 13 .

[0034] The gas injection por...

Abstract

The invention relates to a positive-pressure combustion low-NOx combustor. A fire hole module of the combustor comprises semicircular fire hole plates (11) and a linear fire hole plate (12); and the linear fire hole plate (12) is clamped between the two semicircular fire hole plates (11) to form a semicircular fire hole (13). Compared with the prior art, the positive-pressure combustion low-NOx combustor has the advantages of simple structure, full gas combustion, low nitric oxides, low noise and the like.

Description

technical field [0001] The invention relates to a burner, in particular to a low nitrogen oxide burner for a gas water heater. Background technique [0002] As the country continues to increase its efforts in environmental protection, there will be new standards for the emission of gas appliances, especially for NO x emissions, now gas appliances entering Europe and the United States must have low NO x requirements, while my country's gas appliances NO x Emissions requirements also started in 2012. Existing burners for ordinary wall-hung boilers will produce a large amount of NO during combustion x , which will pollute the environment, and even cause acid rain and endanger the human respiratory system. [0003] Now all gas appliance manufacturers are researching and exploring low-NOx burner products. The thick-lean combustion technology adopted for positive pressure combustion basically follows the burner structure of Japanese companies, especially in the design of the f...
