Abstract
The utility model discloses a natural return flow combustion stabilizer, belonging to an inflamer part, in particular to a combustion stabilizer which can stabilize combustion flames and solves the technical issues of worse stability of the combustion flames in the atomizing enforcement combustion system and being difficult to form a stable columnar flame, comprising a trumpet cylinder and a retainer ring, wherein, the retainer ring with holes opened in the center is fixed with the minorcaliber end of the trumpet cylinder, thus a natural low speed return flow area is formed between the retainer ring and the trumpet cylinder, which is easy to realize the ignition flame and enable the principal flame to burn steadily, more particularly is suitable for use in the combustion system consisting of free-jet-type atomization devices.
Description
Technical field
The utility model belongs to a kind of combustor component, particularly a kind of can smooth combustion flame burning stabilizer.
Background technology
In atomizing forced burning system, because compressed-air actuated flow at high speed, the atomization process strength of turbulence is big, flame holding is poor, thereby is difficult for realizing reliable and stable burning.Chief reason is to be difficult for forming stable igniting burning things which may cause a fire disaster, so be difficult to realize practical application.And there is complex structure in more existing flameholders, are difficult for forming a difficult problem of stablizing column flame.
The utility model content
The purpose of this utility model is: solve flame poor stability in the existing atomizing forced burning system, be difficult for forming the technical problem of stablize column flame, provide a kind of simple in structure, dependence natural back flow mode to form the natural back flow formula combustion stabilizer of stablizing column flame.
In order to realize the purpose of this utility model, the small-bore end of horn-like cylindrical shell of the burning of igniting originally add load onto in the middle of the back-up ring of perforate, so that form the low speed recirculating zone of nature between this back-up ring and the horn-like cylindrical shell, be easy to realize ignition flame, and can make main flame be able to smooth combustion.
Concrete technical scheme is as follows:
Natural back flow formula combustion stabilizer comprises that horn-like cylindrical shell reaches the back-up ring of the fixing center drilling of an end small-bore with it.
Furthermore, described back-up ring is fixedly mounted on the small-bore end outside of horn-like cylindrical shell.
Or described back-up ring (2) is fixedly mounted on a small-bore end inboard of horn-like cylindrical shell (1).
Again furthermore, a small-bore end of described back-up ring and horn-like cylindrical shell welds together.
The back-up ring of the utility model perforate in the middle of the small-bore end of horn-like cylindrical shell installs additional, inject from the stabilizer center at gas-liquid mixed stream at a high speed, naturally the reason that flows owing to air forms secondary gas flow (low speed relatively) in the high-speed jet periphery, and realizes mixing with liquid; And because the effect of stabilizer back-up ring, the mixed combustible gas body of low speed forms comparatively stable backflow at the stabilizer afterbody relatively, realizes igniting back smooth combustion and combustion system is carried out reliable and stable igniting, guarantees combustion system smooth combustion.
As seen, the utility model only on trumpet-shaped cylindrical shell the back-up ring of a center drilling of fixed installation just realized the smooth combustion of fighting of dependence natural back flow mode point of safes, compared with prior art, have simple in structure, burning is reliable, advantage that can smooth combustion, be specially adapted in the combustion system that the jetting type atomizer forms.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1;
Fig. 3 is a use principle schematic diagram of the present utility model;
Number in the figure, the 1st, horn-like cylindrical shell, the 2nd, back-up ring, the 3rd, natural back flow district, the 4th, peripheral flame root area.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Embodiment 1: as shown in Figure 1 and Figure 2, natural back flow formula combustion stabilizer comprises horn-like cylindrical shell 1 and back-up ring 2, and the middle part of back-up ring 2 has the hole.Back-up ring 2 is welded on the small-bore end outside of horn-like cylindrical shell 1, and weld reaches the air-tightness requirement.
During use, this combustion stabilizer is connected with the jetting type atomizer, inject in the stabilizer from the centre bore of back-up ring 2 from the high-speed gas-liquid fluid-mixing that atomizer penetrates, owing to the mobile naturally reason of air, secondary gas flow in the high-speed jet periphery forms as Fig. 3 shown in " secondary air inlet ", the flow velocity of this secondary gas flow is relatively low, and realizes mixing with liquid.
Because the effect of back-up ring 2, the mixed combustible gas body of peripheral low speed relatively forms comparatively stable eddy current at 3 places, natural back flow district of stabilizer afterbody, realize igniting back smooth combustion and the fuel of the peripheral flame root area 4 of combustion system is carried out reliable and stable igniting, determine combustion system smooth combustion, form in the exit of horn-like cylindrical shell 1 and stablize column flame.
In the burning that this device and jetting type atomizer are formed, play critical effect, realized and provide environmental protection stable igniter with simple structure, thereby guaranteed the reliable and stable burning of whole combustion system.
