Fig. 2 is second of embodiment of the steady flame device of the utility model；
Fig. 3 is the main view of Fig. 2, illustrates that the axis of groove favours the axis of bluff body emphatically.
Specific embodiment
By the technology contents of the utility model are described in detail, construction feature, are reached purpose and efficacy, below in conjunction with reality
It applies example and attached drawing is cooperated to be described in detail.
Fig. 1 and Fig. 3 are please referred to, referring to Fig. 1, the steady flame device of the first embodiment includes the steady flame bluff body 1 in center, it should
The groove 12 extended from bluff body center to bluff body edge 11 is provided on bluff body 1, the groove 12 through the bluff body 1 and relative to
The axis of the bluff body tilts.The quantity of groove 12 is 6-18, and in the present embodiment, groove 12 has 9.In this embodiment party
In formula, the groove 12 is dovetail groove, and the upper bottom of the dovetail groove 12 is gone to the bottom towards the edge 11 of the bluff body 1 towards bluff body
Center.The long 20-160mm of the skewed slot of the dovetail groove, upper bottom 3-10mm, bottom 4.5-15mm.The groove 12 favours bluff body 1
25 ° -50 ° of axis, especially as shown in figure 3, dotted portion indicates that groove 12 is located at the part inside bluff body 1 in Fig. 3, groove 12 around
The axis is uniformly distributed, and in the case where bluff body 1 is rounded, the groove 12 extends along radial direction.
Please continue to refer to Fig. 1, the steady flame device further includes that flaring conducting element 2 is provided with around the edge 11 of the bluff body 1,
The axis of the taper of the flaring conducting element 2 and the bluff body forms 55 ° -75 ° of angle.The direction and the injection of gas of flaring 21
Direction is consistent, and in the case where keeping out the wind pipe, the direction of the flaring 21 is with the position for the pipe that keeps out the wind on the contrary, as shown in Figure 2.It is described
The height (i.e. the vertical ranges of both ends of the surface) for being flared conducting element 2 is 10-25mm.At center, the center of steady flame bluff body 1 is connected with gear
The axis of air hose 3, this pipe that keeps out the wind is overlapped with the axis of the steady flame bluff body in center, certainly, it will be understood by those skilled in the art that this is heavy
Conjunction, which can be the two axial lines, certain deviation, even if there is this deviation, can also reach said effect.It uses in 4 holes 14 in Fig. 1
In fixation and install other accessory (burning torch and ion probe).
Fig. 2 and Fig. 3 are please referred to, the steady flame device of second embodiment is compared with the steady flame device of first embodiment, institute
State at least ring through hole 13 being additionally provided on bluff body 1 through the bluff body 1.The circle number of through-hole is 1 to 3 circle and is evenly distributed on institute
It states on bluff body 1,2 circles is illustrated in present embodiment.The axis of each through-hole 13 is parallel to the axis of the bluff body and is formed
Straight hole.The diameter in each hole is 5mm-19mm.In the case where through-hole has multi-turn, difference circle through-holes 13 diameter or
The diameter of through-hole 13 in the same circle of person is unrestricted, can be equal or unequal.In the feelings for being provided with flaring conducting element 2
Under condition, the through-hole 13 from the conducting element 2 to the center arrangement of the bluff body 1, as shown,
Based on above structure, the steady flame device of the utility model is at least had the following beneficial effects:
1, since the steady flame bluff body in center is provided with groove, the axis of the groove is tilted relative to the axis of bluff body, in this way, to few
Amount combustion air makees micro disturbance, generates Whirl deposite tank, promotes the mixing of combustion air and combustion gas, while reducing a large amount of wind centerings
Flame is stablized in the interference of heart burning torch.
2, since the groove is dovetail groove or parallelogram or quadrangle, the upper bottom of the dovetail groove is towards described blunt
The edge of body is gone to the bottom towards the center of bluff body, thus it is possible to the difference of the Zhu Ran air capacity of different locals is controlled, it is further steady
Determine flame.
3, due to the long 20-160mm of the waist of the dovetail groove, upper bottom 3-10mm, bottom 4.5-15mm；The parallelogram
Short side 3-15mm, long side 20-160mm, so, further stable flame.
4, since the groove slant is in 25 ° -50 ° of axis of bluff body, so, the swirl strength of combustion air is controlled,
Stablize flame.
5, since the groove is 6-18, so, the effect for stablizing flame is good.
6, the axis for being parallel to the bluff body due to being evenly arranged with the axis of through-hole and through-hole on the bluff body, in this way,
Groove generates Whirl deposite tank, and through-hole generates axis stream wind, promotes the mixing of combustion gas and combustion air, further decreases the row of nitrogen oxides
It puts, and can guarantee the stability of flame.
7, since the through-hole is 1-4 circle, alternatively, the diameter due to the through-hole is 5mm-19mm, thus it is possible to control
The combustion-supporting air quantity of entire bluff body, stablizes flame, avoids hole circle number too many, causes combustion-supporting air quantity at center excessive, flame is not
It asks.
9, due to being provided with flaring conducting element around the edge of the bluff body, the taper of the flaring conducting element and the bluff body
Axis forms 55 ° -75 ° of angle, in this way, the conducting element carries out water conservancy diversion to combustion air, changes its direction, make combustion air to
The diffusion of outside border, reaches combustion air and preferably mixes with combustion gas.
10, due to being connected with the pipe that keeps out the wind at the center of the steady flame bluff body in center, the axis and the steady flame bluff body in center of this pipe that keeps out the wind
Axis be overlapped, so, which prevents a large amount of combustion air from passing through the installation of the central point firelock at steady flame device center
