Upper air inlet combustor

Abstract

The invention discloses an upper air inlet combustor. The upper air inlet combustor comprises an outer ring gas mixing chamber and two outer ring injection pipes, the gas outlet ends of the two outerring injection pipes both communicate with the outer ring gas mixing chamber, the two gas outlet ends are oppositely arranged in the outer ring gas mixing chamber, a partition plate is arranged in theouter ring gas mixing chamber, the extending direction of the partition plate between the two gas outlet ends is not perpendicular to the facing direction of the two gas outlet ends, the partition plate divides the outer ring gas mixing chamber into two cavities which do not communicate with each other, and the gas outlet ends communicate into the corresponding cavities respectively. According tothe scheme, the partition plate which is not perpendicular to the facing direction of the gas outlet ends is arranged between the two gas outlet ends communicating to the outer ring gas mixing chamber, and the outer ring gas mixing chamber of the upper air inlet combustor is divided into the two relatively independent cavities by the partition plate, so that the two gas outlet ends of the outer ring gas mixing chamber are respectively communicate into the two cavities, and the two gas outlet ends convey fuel gas to the two cavities which are 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.
