Dual-mixture dual-oxygen-supplementation combustor with positioning ignition and flame stabilizing structure and manufacturing method thereof

Abstract

A dual-mixture dual-oxygen-supplementation combustor with a positioning ignition and flame stabilizing structure comprises a liquid bearing plate, a cooker support and an inner / outer ring flame cover, wherein the outer side of the top of the inner ring flame cover is provided with a protruding edge, the outer ring flame cover is arranged on an upper gas mixing plate, a lower gas mixing cavity is further arranged at the bottom of the upper gas mixing plate, and the upper gas mixing plate is provided with a first oxygen-supplementation channel. A second oxygen-supplementation channel is arranged on the outer side of the inner ring flame cover. Optimization is performed by combining with the respectively advantages and shortcomings of side ignition and upper ignition, so that the flame cover meet the efficient ignition rate, and the combustion performance of an ignition hole is not also influenced. In addition, the protruding edge convenient to machine is further added at a thermocouple flame stabilizing hole, so that the gas outlet speed of the flame stabilizing hole is reduced, and accordingly floating flames are not likely to produce. The dual oxygen-supplementation channels can supplement oxygen and can also reduce the internal temperature of the combustor and a cooker product through air flowing, and accordingly the high-temperature environment of internal parts is improved.

Description

technical field [0001] The invention relates to a burner, in particular to a double-mixing double-oxygenation burner with a positioning ignition and flame-stabilizing structure and a manufacturing method thereof, belonging to the technical field of burners. Background technique [0002] The ignition structure of the fire cover is divided into two types. The first is the side ignition structure, that is, the ignition needle ignites on the edge of the fire cover to the eaves of the fire cover. As a result, the ignition position is a place that is not easy to ignite, which affects the success rate of ignition; the second is the upper ignition structure, which can greatly reduce the requirements for the size of parts and assembly errors, thereby ensuring the success rate of ignition, but this type of ignition Because the cover plate of the ignition position is abrupt, the parts are not easy to process, and the fire hole is not convenient to drill. If it is made into a separate p...

AI Technical Summary

Problems solved by technology

The lack of one of the three elements or poor design will lead to a decline in its combustion performance

The disadvantage is that the cost is higher; the pin part of the fire cover is not resistant to impact, so that the pin needs to be specially protected during the manufacturing and transportation process to avoid deformation and affect the use
