Flame stabilizing burner

Abstract

The invention relates to a flame stable burner, characterized in that it comprises a circle or rectangle cup body, a rectangle tube set in the cup body and a taper ring body set at the middle-upper part of the tube; the top edge of said tube is higher than the top edge of said cup body; a distance is stayed between the bottom edge of said tube and the bottom face of said cup body; multiple air inlets are set at the bottom face of said cup body; a fuel nozzle connected with the fuel air source passes through the center of bottom face of said cup body; axes of said cup body, said tube, said ring body and the nozzle are the same. The invention is provided with reasonable design and has a very good path for mutually burning internal and external flame. The path can make external flame burn internal flame when it is burned at the first time and make internal flame burn external flame blown out so that stable burning in the invention can be insured effectively and it is not quenching. The invention can be used in torch in Olympic game or other sports meeting, celebration fire altars and picnic fire.

Description

technical field [0001] The present invention relates to a flame-stabilizing burner, in particular to a flame-stabilizing burner under various harsh environments, such as strong wind, strong shear and extreme turbulence. Background technique [0002] In many practical applications, people need an ideal flame stabilizer to ensure a stable combustion flame under various external wind directions and even hurricanes, strong shear and extreme turbulence. These applications include Olympic or other sporting event torches, ceremonial fire altars and picnic fires. Unfortunately, however, this ideal and simple-structure burner is relatively lacking at present. Generally speaking, a stable flame is achieved by using a blunt body to generate backflow or a strong swirl to form a vortex structure. Although these methods have been successfully applied in some industrial combustion systems, the structure of the swirl is more complicated and difficult to apply to general In daily life, whe...

Yet regrettably, this ideal and simple structure stable burner relatively lacks at present

Generally speaking, a stable flame is achieved by using a blunt body to generate backflow or a strong swirl to form a vortex structure. Although these methods have been successfully applied in some industrial combustion systems, the structure of the swirl is more complicated and difficult to apply to general In daily life, whether a simple blunt body can produce backflow and its shape and size after backflow all depend on the direction and speed of the flow

So these known methods all have obvious limitation, can't be applied under the climate of violent wind (instantaneous wind speed often exceeds 20 m / s even reaches more than 100 m / s) keep flame not extinguished
