Problems solved by technology

[0002] Existing swirling flow external mixing burners used in hotels, restaurants, restaurants or canteens generally include casings, gas nozzles, air chambers and butterfly covers, etc., after the gas ejected from the gas nozzles is mixed with the air ejected from the air chamber Combustion at the butterfly cover, in order to fully mix the gas and air, the air enters the combustion chamber in a high-speed swirling manner, generating a vortex, which makes the combustion noise louder
There is also a premixed burner in which gas is injected into air, and there are problems of fire power dispersion, combustion efficiency, and heat load that cannot meet the requirements for use.

Abstract

The pre-mixing burner includes one burning unit and one ignition unit, and features the burning unit including one gas mixing chamber with upper and lower openings, one air chamber connected to the lower end of the gas mixing chamber and with side opening, one gas inlet pipe stretched into the air chamber from the bottom, one main burning nozzle in the end of the gas inlet pipe, one perforated flame plate in the upper opening of the gas mixing chamber, and porous plates inside the gas mixing chamber to separate the gas mixing chamber into several cavities. The pre-mixing burner has well mixing between the fuel gas and air, complete combustion, high heat efficiency, stable flame and homogeneous heat load.

Description

technical field [0001] The present invention relates to a kitchen burner, more specifically, to a low-noise premixed gas burner. Background technique [0002] Existing swirling flow external mixing burners used in hotels, restaurants, restaurants or canteens generally include casings, gas nozzles, air chambers and butterfly covers, etc., after the gas ejected from the gas nozzles is mixed with the air ejected from the air chamber Combustion at the butterfly cover, in order to fully mix the gas and air, the air enters the combustion chamber in a high-speed swirling manner, generating a vortex, which makes the combustion noise louder. There is also a premixed burner in which gas is injected into air, which has the problems of firepower dispersion, combustion efficiency, and heat load not meeting the requirements for use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a premixed burner with complete pre-mixing of ...
