Abstract

The utility model relates to a rotary flame burner which is characterized in that the upper surfaces of an inner fire cover and an outer fire cover are both in the shape of a circular ring which is inclined inwards, strip-shaped fire outlets from interior to exterior are arranged on the circumference in the upper surfaces of the fire covers, the fire outlets are arranged in a rotary type, and the fire outlet is communicated with a lower air chamber through an inclined air passage in the interior of the fire cover; the flame generated by the utility model is the rotary type flame which rotates inwards to the center of a boiler bottom part from outer circumference, the flame temperature at the center of the bottom part of a boiler is enhanced, the flame is collected in a limited range of the boiler bottom, the flame is prevented from largely dispersing outwards, the temperature distribution on the fire cover is improved, the heat loss is reduced, and the heat efficiency is enhanced.

Description

The swirl flame burner

The utility model relates to a kind of gas stove burner, particularly a kind of swirl flame burner.

The burner of the present gas furnace that generally uses, its fire hole all adopts the perforation formula, and this perforation all outwards is radially distributed in around the inside and outside fire lid.This burning structure, make flame to around disperse, cause the heat loss of stove and accessory very big, the thermal efficiency is low, and the flame distribution at the bottom of the whole cooker is unreasonable, temperature height around the centre temperature is low is unfavorable for heating up water and cooking.

The purpose of this utility model is to provide a kind of flame distribution reasonable, and heat loss is few, the steam stove burner that the thermal efficiency is high.

The purpose of this utility model is achieved in that the swirl flame burner, the upper surface that it is characterized in that inside and outside fire lid is intilted garden annular shape, its surface and horizontal plane angle are between 20 °～40 °, fire lid the inclination position of upper surface respectively have circle bar shaped crater from inside to outside, crater is rotary distribution, between the radius of its direction and fire lid certain angle is arranged, wherein the crater of inner fire cover and radius angle are between 25 °～35 °, and the crater of outer fire cover and radius angle are between 10 °～20 °.The bar shaped crater communicates with following air chamber by the strip airway that tilts in the fire lid, airway and hard Nogata to angle between 40 °～50 °.

The utility model has adopted the bar shaped airway air guide of tilting, revolving bar shaped crater flame, thereby cover at fire and to have formed rotary flame, adopted introversion formula fire to cover the surface, made swirl flame when rotated, the lid that warms oneself in front of a fire is centroclinal, centre flame is more concentrated, flame temperature is higher thereby make, thereby improved the distribution of flame, it is the strongest to form the center firepower, all around the relatively more uniform layout of all directions flame.The flame of inward turning, controlled effectively flame to external diffusion, reduced outwards scattering and disappearing of heat, thereby reached the raising thermal efficiency, save the purpose of combustion gas.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the cutaway view of swirl flame burner

Fig. 2 is in the swirl flame burner, the vertical view of outer fire cover upper surface.

Below in conjunction with embodiment the utility model is done further statement.

Swirl flame burner of the present utility model as shown in Figure 1, interior ring fire lid (1) is an introversion formula garden annular shape with the upper surface of external ring fire cover (2), its inclination angle becomes 30 ° of angles with horizontal plane.Bar shaped crater (3) is the surface that pivotably is distributed in the fire lid.Shown in figure (2), the crater of inner fire cover is 30 ° with fire lid radius angle, and the crater of outer fire cover is 15 ° with fire lid radius angle.Crater (3) communicates with air chamber (4) by the bar shaped airway that tilts, and bar shaped airway and hard Nogata are to 45 ° of angles.When combustion gas from air chamber after airway crater ejection, just formed the intilted rotary flame of two circles.

Claims

1, swirl flame burner, the upper surface that it is characterized in that inside and outside two fire lids is intilted garden annular shape, in the upper surface of fire lid, respectively have circle bar shaped crater (3) from inside to outside, crater (3) is rotary distribution, between the radius of its direction and fire lid certain angle is arranged.

2, according to the described swirl flame burner of claim 1, it is characterized in that the upper surface of inside and outside fire lid, its gradient and horizontal plane angle are between 20 °～40 °.

3, according to the described swirl flame burner of claim 1, it is characterized in that between crater (3) and the fiery radius that covers certain angle being arranged, the crater of inner fire cover and radius angle are between 25 °～35 °, and the crater of outer fire cover and radius angle are between 10 °～25 °.
