Pre-mixing burner

Abstract

The present invention relates to a premixed burner, comprising a main fire device and an ignition device, characterized in that the main fire device includes an air mixing chamber with upper and lower openings, an air inlet opening connected to the lower end of the air mixing chamber and a side wall The air chamber, the air inlet pipe extending into the air chamber from the bottom, the main fire nozzle set at the end of the air inlet pipe located in the air chamber, the fire outlet plate covering the upper opening of the air mixing chamber, the mixing chamber The air chamber is provided with a porous plate which divides the air mixing chamber into multiple spaces, and the porous plate is provided with a plurality of air holes. The air mixing chamber is divided into multiple cavities by setting a perforated plate, so that the air entering from the air chamber and the gas injected by the main fire nozzle on the intake pipe are fully mixed in the multiple cavities separated by the perforated plate, and the combustion is complete and High thermal efficiency; by setting a fire orifice plate at the upper end of the gas mixing chamber, the flame is stable and the heat load is uniform during combustion.

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 ...
