For the burner according to the embodiment of the present application, connected in one one end with incinerator burner hearth.As shown in figure 1, combustion
The right-hand member of burner 100 is connected with incinerator 13, it is, the right-hand member of burner 100 is one end towards incinerator 13.
Exemplarily, for burner 100, the first dividing plate 20 is compared with second partition 22 closer to housing 5, combustion chamber
10th, one end towards incinerator 13 of middle cylinder body 11 and inner barrel 12.
Exemplarily, as shown in figure 1, burner 100 can also be provided with refractory material 15 in the inwall of inner barrel 12, from
And form the refractory liner around combustion chamber 10.
Exemplarily, as shown in figure 1, burner 100 can also include one-level combustion air distributor 4, it is arranged on one
In level combustion air runner, for causing one-level combustion air to be uniformly distributed.
Exemplarily, for the burner 100 shown in Fig. 1, housing 5, combustion chamber 10, middle cylinder body 11 and inner barrel 12 it is logical
Toward the one end open of incinerator 13, the second annular channel, for example, the outlet of tail gas runner 19 is ring exit 16, it is first annular
Runner, the outlet 17 of such as two grades combustion air runners is ring exit.
It should be noted that outlet means the outlet of gas, the outlet of tail gas runner is exactly the outlet of tail gas, and two grades are helped
The outlet of combustion air flow channel is exactly the outlet of two grades of combustion airs.
For the burner 100 shown in Fig. 1, one-level combustion air runner is：One-level combustion air is through one-level combustion air
Entrance 6 enters in burner shell 5, in the cavity formed by the end socket of burner shell 5 and second partition 22, passes through contraction section 9
Into in combustion chamber 10, it is one-level combustion air runner that one-level combustion air, which enters this space passed through after burner,.
Second annular channel, for example, tail gas runner 19 is：Tail gas enters in housing 5 through gas inlet 21, by by first
Dividing plate 20, second partition 22, middle cylinder body 11 and the circular passage of the formation of inner barrel 12, are tail gas runner from annular channel outlet
Outlet 16 is ejected into the burner hearth of incinerator body 13, and it is tail gas stream that tail gas, which enters this space passed through after burner,
Road.
First annular runner, such as two grades combustion air runners 18 are：Two grades of combustion airs are through two grades of combustion air inlets 8
Into in burner shell 5, by the circular passage formed by the first dividing plate 20, burner shell 5 and middle cylinder body 11, from annular
Channel outlet is that the outlet 17 of two grades of combustion air runners sprays, and two grades of combustion airs enter this sky passed through after burner
Between be two grades of combustion air runners.
Alternatively, the entrance of the second annular channel, for example, gas inlet, can be fixed directly through housing, for example,
Welding, on middle cylinder body, so that connected with the second annular channel, and the entrance of first annular runner, for example, two grades of combustion airs
Entrance can be affixed directly to housing, so, and first annular runner and the second annular channel can pass through common dividing plate and one
Level combustion air runner is separated, and correspondingly, first annular runner can be enclosed to set by middle cylinder body, housing and a dividing plate to be formed, and second
Annular channel can be enclosed to set by middle cylinder body, inner barrel and the dividing plate to be formed, in order to which the succinct example arrangement is not showed that.
Exemplarily, fuel air gun component can also be included according to the burner of the embodiment of the present application, as shown in figure 1, should
Fuel air gun group is made up of fuel gas gun barrel 2, fuel gas entrance 3, fuel gas gun sprayer 7, is arranged on one-level combustion air runner
Interior, fuel gas and one-level the combustion air mixed combustion in combustion chamber 10 that fuel air gun sprays form stable flame, are stove
Thorax provides thermal source.
It should be noted that according in the burner of the embodiment of the present application, the setting of fuel air gun component is not limited to Fig. 1 institutes
The example shown, as long as fuel gas can be provided for combustion chamber 10 without limiting its particular location.
Exemplarily, in the burner 100 shown in Fig. 1, the fuel gas gun sprayer 7 of fuel air gun component can be arranged on
Without being provided in combustion chamber 10 in the contraction section 9 of remote incinerator one end of combustion chamber 10, so, fuel gas can received
It is ejected in contracting section 9, so as to just be mixed before fuel gas enters combustion chamber 10 with one-level combustion air, so as to lift combustion
Expect the efficiency of combustion of gas, form more stable flame.Certainly, embodiments herein is not limited to this, fuel gas gun sprayer
It can be arranged directly in combustion chamber.
Exemplarily, altar lamp component can also be included according to the burner of the embodiment of the present application, as shown in figure 1, kept burning day and night
Lamp component 1 is arranged on same one end of burner with fuel air gun component 2, however, the setting of altar lamp component 1 is not limited to Fig. 1 institutes
Show, as long as it can realize function.
With reference to Fig. 1, for the exemplary burner 100 shown in Fig. 1, fuel gas and tail gas are respectively arranged with independent air distribution
System, air from one-level combustion air inlet 6 by one-level combustion air distributor 4 after, by contraction section 9, subsequently into combustion
Room 10 is burnt, so as to form stable flame with fuel gas mixed combustion, required temperature is provided for tail gas from incinerator.And and tail
Gas mixing is then two grades of combustion airs, and tail gas runner exit and two grades of combustion air runner exits are coaxially arranged, it is ensured that the two
It is evenly distributed in after ejection in burner hearth so that tail gas can equably mix enough air, be effectively guaranteed tail gas and fill
Divide and burn completely, and then reduce tail gas levels probability not up to standard after burning.
Further, for the burner according to the embodiment of the present application, tail gas runner and two grades of combustion air runners are
Annular channel, and the two is coaxially arranged, the flow area of tail gas and air is bigger, under same burner dimensions, tail gas and
Air is lower by the pressure drop of burner, and can reduce plant energy consumption.
Moreover, for the technical scheme that the second annular channel is tail gas runner, inner cylinder temperature is higher, and tail gas can be entered
Row preheating, prevents that accumulating sulphur blocks tail gas runner, and if tail gas have passed through heating treatment in itself, then tail gas walks intermediate annular stream
Road can also be preferably incubated.And for the technical scheme that tail gas runner is the first annular runner for being arranged on outside, due to shell
Body directly contacts air, and radiating is very fast, then tail gas may be caused to accumulate sulphur or be unfavorable for insulation.
It should be noted that the tail gas in order to handle different type and composition, can be with root when carrying out burner design
According to being actually needed, the radial thickness of first annular runner and the second annular channel is adjusted, so as to adjust tail gas and two grades of combustion-supporting skies
The ratio of gas so that tail gas can be uniformly mixed enough air, further reduces tail gas levels after burning
Probability not up to standard.
