Description
One, technical field
The utility model relates to burner, is a kind of ceramic burner that has the vertical upward nozzle that is circular layout.
Two, background technology
Ceramic burner is the visual plant on the hot-blast stove of using in the blast furnace ironmaking, the quality of its performance directly has influence on normal operation, service efficiency and the service life of self and blast furnace, uses maximum version that 3 kinds of internal combustion type, external-burning and top ignitions are arranged in hot-blast stove at present.But no matter all be provided with the different ceramic burner of structure on the hot-blast stove of which kind of form.Structurally there is problem in various degree in existing ceramic burner, can cause in the hot-blast stove combustion gas mix with air not good with (or) the air-flow skewness, thereby cause burning problems such as understable, adjusting function difference and flame distribution difference.So just can not satisfy of burden requirement and the wind-warm syndrome requirement of fine blast furnace to hot blast.Have that the hot-blast stove of the problems referred to above usually causes that utilization ratio is low, energy waste, environmental pollution, and service life is short.Therefore, improve burner structure and arrange it is the effective way that improves the hot-blast stove performance, its feature should show as good mixing effect, uniform airflow and distribute and have the backflow smoke pre-heating, thereby reaches flame stabilization, combustion intensity height, adjusting function is strong, heat-transfer effect is good purpose.
Three, utility model content
At above-mentioned situation, the utility model just provides a kind of ceramic burner that has the vertical upward nozzle that is circular layout, it can effectively solve and overcome combustion gas that existing burner exists mix with air not good with (or) the air-flow skewness, thereby cause burning problems such as understable, adjusting function difference and flame distribution difference.The technical scheme that this burner solves is to include burner body of wall, gas preheating circuit, combustion air preheating circuit and upper, annular interlaced arrangement coal gas and air port.Gas preheating circuit and combustion air preheating circuit are in the vertical body of wall that is arranged in burner to staggering, the vertical gas exit and the spout at top thereof are arranged at gas preheating circuit top, gas entry with gas preheating circuit vertical connection is arranged on the outer body of wall, gas entry top is combustion air preheating circuit, its wall outer side is the vertical combustion air inlet that inserts, its body of wall inboard is the combustion air outlet that hoop is arranged, this outlet with the same circuit of gas exit position on upwards turnover, its top is furnished with air port, forms annular interlaced arrangement with gas port.The utility model structure is unique and novel, solve effectively and dexterously that air-flow mixes, air-flow distributes, with the key issue of combustion process such as smoke pre-heating, realize flame stabilization, improved combustion intensity, improve heat-transfer effect, reach and improve Load Regulation function etc., and then fuel saving, saving investment, reduction EGT and discharge capacity, effectively prolong the service life of hot-blast stove, its economic and social benefit is huge.
Four, description of drawings
Fig. 1 is the front view of ceramic burner structural profile of the present utility model.
Fig. 2 is the A-A cross sectional plan view of ceramic burner structure of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
By Fig. 1, shown in Figure 2, the utility model includes body of wall and gas preheating circuit and combustion air preheating circuit, gas preheating circuit 2 is vertical disclination with combustion air preheating circuit 5 and sets in burner body of wall 3, the spout 9 at vertical gas exit 21 and top thereof is arranged at vertical gas preheating circuit 2 tops, the gas entry 1 that is communicated with vertical gas preheating circuit is arranged on the body of wall 3, combustion air inlet 4 that the combustion air preheating circuit 5 of gas entry upper vertical and body of wall are outer and the combustion air outlet 6 in the body of wall are connected, and air port 8 is arranged at combustion air outlet top.
The inlet of said vertical gas preheating circuit 2 and vertical combustion-supporting chamber's air preheat circuit 5 is the tangent-type import; Air port 8 and gas port 9 be for vertically upward, cross arrangement (seeing shown in Figure 2), and its nozzle is rectangle or circle, the coal gas of ejection, air carry out high temperature preheating through high temperature reflux to coal gas and air before mixing, improve ignition temperature.Be on vertical gas preheating circuit and the vertical air preheat circuit to intersect and be provided with dozens of outlet (collection) and manage.
By as can be seen above-mentioned, the utility model is owing to adopted the preheating circuit of coal gas and combustion air, air and coal gas vertically upward spray mixing, and the preheating of the flue gas that is subjected to turning back, thereby improve burning condition, improve combustion intensity, the uniform distribution of its thermal current of turning back can effectively improve the utilization ratio of heat storage.Hot fluid presents the even distribution characteristics of Turbulence Flow in the pipe in the hot-blast stove of the present utility model, be beneficial to very much heating to the bottom heat storage, and existing hot-blast stove is quite different, in the middle of thermal current distributes and to be low (even reverse flow) and the high flow performance in both sides causes the heat storage middle part to can not get abundant heating.
So the utility model obviously is different from the characteristics of existing ceramic burner and exists:
1, coal gas, air vertically upward spray, and by means of high temperature gases recirculating it are carried out in hot-blast stove High temperature preheating, the staggered injection of warp mixes cmpletely it and burns, and reaches sufficient combustion, ignition temperature Height, the purpose that the heat load adjustment scope is big;
2, coal gas, air vertically upward spray after-combustion, turn back under the effect of hot-blast stove vault, the downward thermal current that formation temperature and speed all are evenly distributed then enters the top of hot-blast stove heat storage, thereby heat storage is heated evenly, can reaches the high and stable requirement of hot blast of hot blast temperature;
3, the air inlet pipe of coal gas circuit and air circuit is tangential the access, makes to arrange evenly that separately staggered tens outlets (collection) Guan Zhongneng obtains mean error less than ± 5% VELOCITY DISTRIBUTION, mixes thereby improve circumferential air-flow, improves the integral combustion effect;
4, because the utility model has been realized overall uniform burning and diabatic process, the heat storage of the used hot-blast stove of the comparable co-content blast furnace of the height of its heat storage can reduce by 20%, has saved investment effectively.
In a word, the utility model is the inventive improvements of ceramic burner that existing hot-blast stove is used, and structure is more scientific and reasonable, is easy to more promote the use of, and huge economic and social benefit is arranged.
