up air burner

Abstract

The invention discloses an upper air inlet burner, which comprises an outer ring air mixing chamber and two outer ring injection pipes, the gas outlet ends of the two outer ring ejection pipes are connected to the outer ring air mixing chamber, and the two outlet The gas port ends are arranged opposite to each other in the outer ring gas mixing chamber, and the outer ring gas mixing chamber has a partition, and the extension direction of the partition between the two gas outlet ends is not perpendicular to the orientation direction of the two gas outlet ends, and the partition divides the outer ring The gas mixing chamber is divided into two chambers which are not connected to each other, and the gas outlet ports are respectively connected to the corresponding chambers. In this scheme, a baffle that is not perpendicular to the direction of the gas outlet is set between the two gas outlet ports connected to the outer ring air mixing chamber, and the outer ring air mixing chamber of the upper air inlet burner is divided into The two relatively independent chambers make the two gas outlet ports of the outer ring gas mixing chamber communicate with the two chambers respectively, so that the two gas outlet ports can deliver gas to the two chambers separated from each other.

Description

technical field [0001] The invention relates to an upward air intake burner. Background technique [0002] The traditional bottom-intake stove burner has the advantages of high heat load and large firepower. However, since the air replenishment of the bottom air-intake burner is carried out in the cabinet, it is easy to cause insufficient air replenishment, resulting in insufficient combustion, yellow flame and high carbon monoxide concentration. Therefore, an upward air intake type stove burner was created to solve the problem of insufficient air supplementation. [0003] However, due to the short ejector tube of the upward air-intake burner, there is no contraction section and expansion section in the traditional sense, resulting in insufficient ejection capacity, so at least two ejector tubes are generally installed to increase the combustion load of the burner. In order not to affect the normal use of the user and cause no danger, the outlets of the two injection pipes...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an upward air intake burner to overcome the defect that the ejector tube of the upward air intake burner in the prior art has an unstable combustion state at the fire hole due to the relative outlet.
