Energy-saving and high-efficiency lower air inlet gas burner and manufacturing method thereof

Abstract

The invention discloses an energy-saving and high-efficiency lower air inlet gas burner and a manufacturing method of the energy-saving and high-efficiency lower air inlet gas burner. The energy-saving and high-efficiency lower air inlet gas burner comprises an outer fire cover, an inner fire cover and a base, and further comprises an outer fire head part and a flame stabilizing fire ring. The outer fire head part and the flame stabilizing fire ring cooperate with each other to form a secondary air channel. The outer fire head part is provided with the inner fire head part. The secondary air channel faces the inner fire head part, so that the inner fire cover radially communicates with external air for air supplement. The method comprises the following steps of base processing, outer firecover and inner fire cover processing, flame stabilizing ring processing, outer fire head part processing and burner assembly. According to the energy-saving and high-efficiency lower air inlet gas burner and the manufacturing method of the energy-saving and high-efficiency lower air inlet gas burner, through the design of the secondary air channel, secondary air required for uniform pressure of the head portion of the burner and sufficient inner fire is ensured; an inner fire nozzle is convenient to replace by adopting a built-in vertical inner injection pipe; and the manufacturing method ofthe burner is simple, the processing efficiency and the processing quality of the burner are improved, disassembly and maintenance are convenient, and the manufacturing cost of a product is reduced.

Description

technical field [0001] The invention relates to an energy-saving and high-efficiency down-air intake gas burner and a manufacturing method thereof. Background technique [0002] The gas burners used in cookers are all premixed atmospheric burners. The primary air required for combustion is taken from the upper air intake burner above the cooker panel, and the lower air intake burner is taken from the bottom of the cooker panel. The bottom-inlet burner is the burner with the longest application history. It is widely used in household gas stoves due to its simple structure, low manufacturing cost, sufficient mixing of gas and air, and small thermal resistance of the nozzle. In recent years, with the gradual improvement of the design and manufacturing level, the combustion conditions, combustion stability, heat flow and energy-saving performance of the lower intake air burner have been improved compared with the early products. With new technologies, new materials, With the a...

AI Technical Summary

Problems solved by technology

The path of the mixed air flow in the injection tube is long, and the pressure loss along the way is relatively large, which has a significant impact on the internal fire combustion condition and heat flow

[0006] c. The structural design of the inner and outer fire covers and the parameter setting of the fire hole are unreasonable, and the diameter of the fire cover is blindly increased in order to increase the heat flow
