Description
Technical field
The present invention relates to Taiji gas flame stabilizing burner, particularly about a kind of under various adverse circumstances, as violent storm with extremely under the turbulent flow, burner that can both smooth combustion.
Background technology
In many practical applications, people need a kind of desirable stable stabilizer, to guarantee in various wind outside providing stable combustion flame under the situation of wind-force even violent storm and extreme turbulent flow.These application comprise the Olympic Games or other sports meet torch, celebration fire spot and picnic fire.Yet regrettably, the simple stabilizer of this ideal and structure lacks at present relatively.In general, the retention flame reaches by using bluff body generation backflow or strong eddy flow to form vortex structure, though these methods are applied in some industrial combustion system and have obtained success, be difficult to be applied in the general daily life but hydrocyclone structure is complicated, all depend on relevant mobile direction and velocity magnitude with size and can simple bluff body produce backflow and produce its shape of back that refluxes.So these methods of having known all have tangible limitation, can't be applied in that (instantaneous wind speed often surpasses 20 meter per seconds even reaches more than 100 meter per seconds) keeps flame not go out under the weather of blast brutality.In order to break through the limitation of conventional method, the present inventor thinks that novel burner must have a kind of structure, thereby it can both be created good burning situation in different wind outside and burning can both be stablized under various conditions carry out under changing with precipitate wind speed.
Summary of the invention
The purpose of this invention is to provide a kind of flame under various conditions and do not put out, and have a burner that can keep smooth combustion.
For achieving the above object, the present invention takes following technical scheme:
Taiji gas flame stabilizing burner, it is characterized in that: it comprises that a cup and puts the S shape shim in the cup, the central symmetry axis of described cup axis and shim overlaps fully, the rim of a cup of described cup is opened fully and the bottom of described cup is provided with two fuel nozzles, described fuel nozzle bottom is fuel inlet, offers air intlet around the described cup.
Described fuel jet nozzle the bottom surface that the position is higher than described cup is set, but be lower than described cup height half.
Described air inflow aperture be arranged on described cup wall of cup or the cup end on or the two combination.
Described mixed airflow outlet is exactly the outlet of described cup.
Described cup shape of cross section is the combination of a kind of and more than one shapes in circle, Long Circle, the polygon.
Described S type shim shape of cross section is that the broken line a kind of and above-mentioned curve in the Diagram of the Supreme Ultimate, two semicircles, Archimedes spiral, the cardioid approaches.
Described cup lateral section shape is vertically, curves inwardly, a kind of and more than one cooperations in outwardly-bent, the trapezoidal inclination.
The cross sectional shape of described fuel jet nozzle is a kind of in circle, Long Circle, the polygon.
Described shim can be higher than also can be lower than cup.
The present invention is owing to take above technical scheme, and it has the following advantages: 1, the present invention makes and has formed two cavitys in the cup owing to be provided with a S shape shim; When burning generation and low wind speed, after gaseous fuel enters cup by nozzle, overwhelming majority flame occurs in top, cup outside, and the flame in the cup only accounts for a very little part, the required oxygen material of cup internal combustion, therefore then provided in air intake enters cup by extraneous air, the flame in the cup can play the effect of the external firing that continues to ignite; When outer lateral when wind speed increases, little vortex keeps flame not extinguish in negative pressure wake flow and the chamber thereby form in inboard some position of rim of a cup.2, form the cavity of a shielding in the cup of the present invention, therefore make stabilizer its internal flow structure have autostability, in this case, local instantaneous velocity in the cavity under any circumstance all can be controlled in burning and extinguishes under the velocity amplitude of requirement, and then the flame of having avoided effectively lighting is blown out by swiftly flowing wind-force.3, because geometry provided by the invention design can be controlled extraneous air and enter flowing in the cup, make the mixing of air and fuel reach optimum state; Simultaneously because reasonable structural design, make the present invention have the path of igniting mutually of well inside and outside flame, this path both can make the external flame internal flame of igniting when being lighted for the first time, the also external flame that can make internal flame ignite and be put out, thereby guaranteed smooth combustion of the present invention effectively, and do not extinguished.
Description of drawings
