Description
Technical field
The utility model is related to the burner arts of water heater, more particularly, to a kind of stable flame combusting device.
Background technology
In recent years, the increasingly attention with people to environmental protection, natural gas is as a kind of clean energy resource gradually by big
The favor of family.And gas heater, as the major product of gas utensil, the design optimization of its burner is also in widespread attention.
As the improvement of people's living standards, the demand to water heater gradually changes to Large Copacity direction, and with hot water
The increase of device capacity, certainly will will increase fire hole area, so the increase of combustion chamber volume can be caused to make water heater excessively huge.Such as
Fruit does not increase fire hole area, then the exit velocity of fire hole premixed gas can be too high, causes pre-mixing gas combustion outlet speed to be more than combustion gas
Burning velocity, produces de- fire and from flame.
In order that burning carries out in less combustion chamber and is unlikely to de- fire, be to the flame at the main fire hole of burner
Carry out steady flame.The steady flame measure typically taken all is that single aperture is beaten in primary combustor side walls, then in side wall external welding one
The steady flame plate of block, forms the cavity of one, so that the combustion gas flowed out from burner body side aperture shape at cavity outlet
Into the burning of one small fire, steady fireworks flame is used as.But due to steady flame plate and the cavity gas outlet sectional area of combustor sidewalls formation
It is too big, and side wall aperture perforate spacing is larger, and the gas flowing needed for causing steady flame burning is chaotic, and steady fireworks flame effect is poor,
Steady fireworks flame effect difference can then cause burner flame to occur de- fire.
Utility model content
In order to solve problems of the prior art, the utility model provides a kind of new stable flame combusting device, overcomes existing
There is gas heater flame stability in technology poor, the problem of combustion chamber volume is big.
The technical solution adopted in the utility model is：A kind of new stable flame combusting device, the burner assembly is included provided with combustion
Fire hole face is provided with the top of the burner body of gas passage, the burner body, burner body head both sides are provided with steady flame
Seam, one piece of stable flame piece of two side external welding of body, the steady flame chamber of formation one, steady flame chamber passes through steady flame seam and connected with blast tube
Logical, one end of each steady flame chamber correspondence gas outlet is provided with stable flame hole.
Preferably, fire hole face sets the non-burning region for having wide 3mm between three fire hole groups, fire hole group, pre- in this region
Mixed gas can be contacted with auxiliary air, make burning more abundant.The steady flame plate on burner body both sides, is connected by iron plate,
And steady flame chamber is divided into three parts, corresponded with three fire hole groups, three steady flame chambers pass through steady flame slot apertures and the combustion
Gas passage is connected.
Preferably, fire hole group in fire hole face is that size fire hole is spaced.Big fire hole ensure that the requirement of burner load；It is small
Fire hole middle part is separated, and is so reduced the internal flame of flame, is improved the stability of burning.
Preferably, the width of each fire hole is 0.6mm.
Preferably, steady vertical range of the flame seam away from fire hole face is 7mm described in the wall of side.
Preferably, the bar slit width degree of steady flame seam is 0.2mm.
Preferably, the ratio between bar seam area and the fire hole gross area of steady flame seam are 1:10.
The beneficial effects of the utility model are：Compared with traditional stable flame combusting device, stable flame combusting device of the present utility model
Traditional combustion gas via is instead of using steady flame seam on the wall of side, alleviates and the excessive steady flame gas brought of pitch of holes is crossed on the wall of side
Air turbulence, has steady flame air-flow and more stablizes upward speed, make steady fireworks flame more stable.Using two big fire hole,
The fuel element of one small fire hole composition, on the premise of both meeting burden requirement, improves the stability of burning again.Steady flame seam with
Being correspondingly arranged for fuel element, makes main flame and steady fireworks flame more stablize.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As Figure 1-Figure 5, the utility model includes burner body 1, and burner body 1 is provided with fire hole face 2, fire hole
Face 2 is provided with three groups of fire hole groups 3, and one piece of stable flame piece 4, stable flame piece 4 and this body sidewall formation one are welded in the both sides of burner body 1
Individual cavity, referred to as steady flame chamber 8, steady flame chamber 8 is connected by steady flame seam 6 with blast tube, and steady flame gas is stitched from main body 1 by steady flame
6 flow into steady flame chamber 8.Steady flame chamber 8 is exported is divided into three stable flame holes 7 by iron plate 5, each described stable flame hole 7 and a fire
The correspondence of hole group 3.So that the steady fireworks flame Relatively centralized sprayed from stable flame hole 7, is carried out more preferable to the flame at fire hole group 3
Steady flame.
The big fire hole small fire hole of every group of fire hole is spaced, and each fire hole group includes three fuel elements, and such as Fig. 5 each burns
Unit is spaced by two big fire hole 32 and a pair of small fire holes 31.Big fire hole 32 and small fire hole 31 spacing b is in fuel element
1.2mm.The spacing c of the setting small fire hole 31 between fuel element, fuel element and small fire hole 31 is 1.8mm.
It is using two big fire hole 32 and a pair of small fire holes 31 spaced, it is contemplated that fuel element internal flame is contacted with oxygen
Probability is relatively low, and internal flame can be reduced using small fire hole 31 in the middle part of fuel element, improves combustion stability, and fuel element both sides
It is higher with oxygen contact probability, using big fire hole 32, burner is had higher burning load.Because big fire hole 32 is deposited
, the width a of single fire hole is smaller than conventional burners, width a be 0.6mm, by reducing the width of single fire hole, make flame
Segmentation is more refined, and adds combustion gas and oxygen combination probability, is conducive to the progress of reaction, so as to improve combustion efficiency.
The utility model flows chaotic, the problem of steady fireworks flame is not concentrated, in the side wall of main body 1 to solve steady flame gas
On, steady flame seam 6 has been used as steady flame chamber 8 and the interface channel of main body 1.The quantity of steady flame seam 6 is also three, with three steady flames
Hole 7 and three fire hole groups 3 are corresponded.
Aperture is used as passage with traditional, and steady flame gas flows out steady flame and is sewed with more preferable flox condition, due to pressure
Uniformly, steady flame gas flow direction can preferably keep up without left and right skew, the so steady fireworks flame after burning also more
Concentrate stable.
Be not the main place of burning because steady fireworks hole mainly provides steady fireworks flame, thus steady flame seam 6 area not
It is preferably too big.Preferably, the ratio between bar seam area and the gross area of fire hole group 3 of steady flame seam 6 are 1:10.Preferably, steady flame described in the wall of side
The 6 vertical range d away from fire hole face 2 of seam are 7mm.Preferably, the slit width e of the steady flame seam is 0.2mm.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
