The utility model discloses a kind of burner external ring fire cover, comprise external ring fire cover body, the periphery wall of external ring fire cover body offers one and iris out fire hole one, the inner ring of described external ring fire cover body is provided with the scarf tilted to center position, the angle of inclination of scarf is 40 ~ 45 degree, scarf is furnished with multiple fire output hole two, the periphery wall of external ring fire cover body is inclined upwardly, and its angle of inclination is 22 ~ 26 degree.The advantages such as the utility model burner external ring fire cover has the thermal efficiency, and simultaneously firing rate is fast.
Description
Technical field
The utility model relates to technical field of burner, is specifically a kind of burner external ring fire cover.
Background technology
Existing a kind of burner external ring fire cover, comprises external ring fire cover body, the periphery wall of external ring fire cover body offers one and irises out fire hole.Adopt the burner external ring fire cover of this structural design, during use, thermal losses is large, and firing rate is slow.
Summary of the invention
The purpose of this utility model is: provide one to improve the thermal efficiency, accelerates the burner external ring fire cover of firing rate simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of burner external ring fire cover, comprise external ring fire cover body, the periphery wall of external ring fire cover body offers one and iris out fire hole one, the inner ring of described external ring fire cover body is provided with the scarf tilted to center position, the angle of inclination of scarf is 40 ~ 45 degree, scarf is furnished with multiple fire output hole two, the periphery wall of external ring fire cover body is inclined upwardly, and its angle of inclination is 22 ~ 26 degree.
The utility model compared with prior art, has the following advantages: the flame of the utility model burner external ring fire cover fire output hole two ejection is towards center, and firepower is more concentrated, effectively can reduce thermal losses, improves the thermal efficiency, can also improve firing rate simultaneously; The angle of inclination of scarf is designed to 40 ~ 45 degree, and the flame that under this angle of inclination, fire output hole two sprays is the most stable, and the bottom of a pan is heated evenly; The periphery wall of external ring fire cover body is inclined upwardly, the fire output hole one offered thereon is also inclined upwardly, flame sprays to the oblique upper of fire output hole one, so, greatly can increase the contact area in flame and the bottom of a pan, the flame of ejection can be fully used, and effectively improves firing rate and the thermal efficiency; Meanwhile, the angle of inclination of external ring fire cover body peripheral wall is designed to 22 ~ 26 degree, the flame that under this angle of inclination, fire output hole one sprays is the most stable, and the bottom of a pan is heated evenly.
Further, the below periphery wall of described external ring fire cover body being positioned at fire output hole one is provided with a circle stable flame hole, and stable flame hole and fire output hole one are crisscross arranged.Stable flame hole plays steady flame effect to the flame sprayed from fire output hole one, makes flame more stable, and heating effect is better, and meanwhile, stable flame hole and fire output hole one are designed to cross structure, and steady flame effect is better.
Further, the angle of inclination of described scarf is 42.5 degree.Through test of many times, when 42.5 degree, the angle of inclination of scarf, firepower localization effects is best, and heating effect is best.
Further, the angle of inclination of described periphery wall is 24 degree.Through test of many times, when the angle of inclination of periphery wall is 24, the flame of ejection is the most stable, and heating effect is best.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model burner external ring fire cover.
Fig. 2 be the utility model burner external ring fire cover face structural representation.
Shown in figure: 1, the angle of inclination δ of external ring fire cover body 2, fire output hole 1, fire output hole 24, stable flame hole ε, periphery wall, the angle of inclination of scarf.
Detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of burner external ring fire cover, comprises external ring fire cover body 1.The periphery wall of external ring fire cover body 1 offers one and iris out fire hole 1.The inner ring of external ring fire cover body 1 is provided with the scarf tilted to center position, the angle of inclination δ of scarf is 40 ~ 45 degree, scarf is furnished with multiple fire output hole 23.
The flame of the utility model burner external ring fire cover fire output hole 23 ejection is towards center, and firepower is more concentrated, effectively can reduce thermal losses, improves the thermal efficiency, can also improve firing rate simultaneously; The angle of inclination δ of scarf is designed to 40 ~ 45 degree, and the flame that under this angle of inclination, fire output hole 23 sprays is the most stable, and the bottom of a pan is heated evenly.
The periphery wall of external ring fire cover body 1 is inclined upwardly, and its angle of inclination ε is 22 ~ 26 degree.The periphery wall of external ring fire cover body 1 is inclined upwardly, the fire output hole 1 offered thereon is also inclined upwardly, flame sprays to the oblique upper of fire output hole 1, so, greatly can increase the contact area in flame and the bottom of a pan, the flame of ejection can be fully used, and effectively improves firing rate and the thermal efficiency; Meanwhile, the angle of inclination ε of external ring fire cover body peripheral wall is designed to 22 ~ 26 degree, the flame that under this angle of inclination, fire output hole 1 sprays is the most stable, and the bottom of a pan is heated evenly.
The below periphery wall of external ring fire cover body 1 being positioned at fire output hole 1 is provided with a circle stable flame hole 4, and stable flame hole 4 and fire output hole 1 are crisscross arranged.Stable flame hole 4 plays steady flame effect to the flame sprayed from fire output hole 1, makes flame more stable, and heating effect is better, and meanwhile, stable flame hole 4 and fire output hole 1 are designed to cross structure, and steady flame effect is better.
The angle of inclination δ of scarf is 42.5 degree.Through test of many times, when the angle of inclination δ of scarf is 42.5 degree, firepower localization effects is best, and heating effect is best.
The angle of inclination ε of periphery wall is 24 degree.Through test of many times, when the angle of inclination ε of periphery wall is 24, the flame of ejection is the most stable, and heating effect is best.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its scope protected according to right.
