Described burner noz(zle) seat 2 is provided with the axial burner noz(zle) 4 (being provided with a plurality of axial burner noz(zle)s 4 in Fig. 4) that at least one is communicated with described burner noz(zle) seat 2 fluids along its central axis X-X in its downstream, the opening of described axial burner noz(zle) 4 is towards the downstream direction of described burner noz(zle) seat 2.
In addition, described burner noz(zle) seat 2 therein axle line X-X around also be provided with at least two radial combustion nozzles 5 that are communicated with described burner noz(zle) seat 2 fluids, the opening direction of described radial combustion nozzle 5 is roughly along the radial direction of described burner noz(zle) seat 2.
With the opening of described radial combustion nozzle over against the position on, the described shade 3 that keeps out the wind is provided with the flame that the combustion flame 5f for described radial combustion nozzle 5 passes and sprays window 31.
Around the described shade 3 that keeps out the wind, be provided with the kuppe 6 of a general cylindrical shape, be provided with a blower fan (not shown) in the updrift side of described burner noz(zle) seat 2, described blower fan to described downstream direction air feed so that the combustion heat is sent.
As shown in Figure 1, kuppe 6 is sat the exit of putting at blower fan by the adpting flange of its configuration, and this flange links to each other with the outlet that is connected extension set by for example bolt.
The inwall of kuppe 6 is connected with the shade 3 that keeps out the wind by the setting element (not shown), thereby the shade 3 that will keep out the wind is fixed therein, and makes the shade that keeps out the wind roughly overlap (this axis that is X-X) with the axis of kuppe.
Because adopt said structure, the principal advantages that the burner of fuel gas provided by the present invention has is as follows:
The setting of shade 3 owing to keep out the wind, the air-flow (shown in the arrow among Fig. 1) that blower fan produces can not impact (that is, flame blow-off) to the burning of fuel gas.This is that the air-flow that blower fan produces blows the root less than combustion flame 5f because the outlet of radial combustion nozzle 5 is positioned at shade 3 inside of keeping out the wind.And the flame of the flame envelope of combustion flame 5f by relative set on the shade 3 that keeps out the wind sprays window 31 and is positioned at outside the shade 3 that keeps out the wind, thereby the air-flow that blower fan produces can blow to the flame envelope of this flame 5f and by the direct-fired air of this flame 5f.Therefore, thus the burner of fuel gas provided by the invention can the combustion heat of fuel gas be forced to send the combustion space by blower fan the combustion heat is used.
Above-mentioned principal advantages is particularly favourable for the burning passage of heat of the hydrogen fuel energy sources of hydrogen and oxygen mixture (its burning velocity is fast, and flame is very concentrated, and the caloradiance that is produced is very little, and heat distance is very short) especially.This is because the air-flow that blower fan produces can blow to the flame envelope of combustion flame, thereby can directly and be to greatest extent the combustion heat to be sent and be used.
The quantity of described radial combustion nozzle 5 can be 2～36; More preferably, the quantity of described radial combustion nozzle is 3～60.
The quantity of the radial combustion nozzle 5 shown in Fig. 1 is two.And the quantity of the radial combustion nozzle 5 shown in Fig. 2 is six.These quantity all are exemplary.In concrete the use, this quantity can change as required.
As shown in Figure 1, the angle α of the central axis X-X of the central axis of described radial combustion nozzle 5 and described burner noz(zle) seat 2 is 5～95 °, more preferably 5～30 ° of this angles.
The setting of this angle makes air-flow be an acute angle with the angle of combustion flame 5f in the circular passage of keeping out the wind between shade 3 and the kuppe 6, thereby helps sending heat, and alleviates the interference that burning is caused.
As shown in Figure 1, the top of described axial burner noz(zle) 4 protrudes in the top edge of the described shade 3 that keeps out the wind.
So, axially the combustion flame 4f of burner noz(zle) 4 ejections protrudes in the shade that keeps out the wind, thereby thermal current is played certain guiding and centering effect.
As Fig. 1 and shown in Figure 2, be less than or equal to 5 millimeters apart from d between the inwall of the top of described radial combustion nozzle 5 and the described shade 3 that keeps out the wind.
If described too little apart from d, the burning difficulty then can take place; And if too big apart from d, then combustion flame 5f descends with the degree of accuracy that cooperates that flame sprays window 31, the efficient of device will be influenced.
As Fig. 2 and shown in Figure 3, also be provided with a plurality of gases rotation water conservancy diversion fins 7 on the outer wall of the described shade 3 that keeps out the wind, described a plurality of gases rotation water conservancy diversion fins 7 can be separately positioned on each described flame relative with each described radial combustion nozzle 5 and spray between window 31.
In addition, described a plurality of gas rotation water conservancy diversion fin 7 also can be separately positioned on top or the below (not shown) that each described flame relative with each described radial combustion nozzle 5 sprays window 31.
The quantity of described gas rotation water conservancy diversion fin 7 can be less than or equal the quantity of described radial combustion nozzle 5 and the quantity that described flame sprays window 31.
As shown in Figure 3, the layout track of described a plurality of gas rotation water conservancy diversion fins 7 on the annular outer wall of the described shade 3 that the keeps out the wind shape that rises in the shape of a spiral, in other words, this layout track both had been not parallel to central axis X-X, also be not parallel to the diametral plane vertical with this central axis X-X, but between between the two.
As shown in Figure 3, the central axis (that is X-X) of more any tangent line in this track and the described shade 3 that keeps out the wind forms 5～85 ° angle β.More preferably 5-30 ° of this angle β.
The shape because the layout track of described a plurality of gas rotation water conservancy diversion fins 7 on the annular outer wall of the described shade 3 that keeps out the wind rises in the shape of a spiral, the ascending air that blower fan is produced produces spirally-guided, thus it is more even that air-flow is mixed, and heat transfer effect is better.In addition, described a plurality of gas rotation water conservancy diversion fins 7 also have a function, that is, and and " damping effect " of indirect.
If gas rotation water conservancy diversion fin is not set, be difficult in circumferencial direction from the hot blast of kuppe 6 outlets and form the average temperature effect of Denging, particularly nozzle is particularly evident after a little while.For example, when from overlook direction (that is, direction from Fig. 2) if 4 intervals, 90 degree just is set when seeing when the uniform axial burner noz(zle) 5 of circumferencial direction, if gas rotation water conservancy diversion fin is not set, then be starkly lower than leaving air temp corresponding to the leaving air temp in the zone outside the position of 4 axial burner noz(zle)s 5 corresponding to the position of 4 axial burner noz(zle)s 5 in the exit of kuppe 6.So cause leaving air temp inhomogeneous.And being provided with gas rotation water conservancy diversion fin (quantity that perhaps increases axial burner noz(zle) acquires a certain degree) afterwards, leaving air temp is just even.Here it is above-mentioned " damping effect ".
Shown in Fig. 4 and Fig. 5 is the of the present invention second basic embodiment.In this second basic embodiment, be with the main difference part of above-mentioned first basic technical scheme: described burner noz(zle) seat 2 therein axle line X-X around also be provided with two-layer at least (in other words, multilayer) the radial combustion nozzle 5 that is communicated with described burner noz(zle) seat 5 fluids.The quantity of each layer radial combustion nozzle 5 is 2～15, and each layer arranged on the central axis X-directions X of described burner noz(zle) seat 2 at each interval.
