Technical field
The utility model relate to a kind ofly be applied to metallurgy industry, especially for the baking behind the continuous casting tundish dry material molding construction, different according to bond, 300~500 ℃ of heating-up temperatures; Serviceability temperature is low; Anti-vibration, burner is installed in its upper side, and flame is downward; Burner must corrode and radiation by the heat resistanceheat resistant air-flow, and this burner also can be used on the Thermal Equipments such as casting, anti-material, machinery, heat treatment, boiler.
Background technology
Integrated iron and steel works will reclaim a large amount of low-heat value gas every year, mainly contain coal gas of converter and blast furnace gas, owing to coal gas of converter calorific value high (6.2~6.7Mj/m), can be widely used in heating furnace; Cement rotary kiln, ladle baking facility, tundish roaster; Boilers etc., and blast furnace gas calorific value low (3.0~3.7Mj/m) self independently use very difficulty; Be generally used for blast funnace hot blast stove at present, recuperative heater etc., and blast funnace hot blast stove and recuperative heater all possess coal gas or preheating of air condition when using blast furnace gas; In case take the preheating measure, combustion position improves greatly, combustion stability strengthens; Safety in utilization improves, and in order to enlarge the blast furnace gas range of application, also can blast furnace gas be mixed use with exotic fuels (like coke-stove gas); But,, still have the part blast furnace gas to diffuse usually because blast furnace gas output is big; Cause environmental pollution and energy waste, and exotic fuels are very in short supply, so exploitation blast furnace gas burner; Enlarge the application and the use amount of blast furnace gas, alternative exotic fuels have important application and vast market prospect, the succeeding in developing of this burning device; Can enlarge the application of blast furnace gas, reduce blast furnace gas and diffuse, practice thrift enterprise's fuel consumption cost; Increasing economic efficiency, also can reduce environmental pollution, is a product with significant application value.
The utility model content
The purpose of the utility model is to provide a kind of burner, and this burner can satisfy and independent uses blast furnace gas, and combustion air just can smooth combustion under can't the condition of preheating, can enlarge the application of blast furnace gas.
The technical scheme of the utility model is achieved in that
The blast furnace gas burner is used in the tundish dry material baking, comprises flameholder 1, mixing tube 2, coal gas current divider 3, air cyclone 4, burner fixture 5, burner body 6, gas pipe 7 and air hose 8; Air hose 8 is connected with the sidewall of burner body 6, and gas pipe 7 inserts in the burner body 6, and an end of gas pipe 7 exposes from burner body 6, and the other end connects air cyclone 4, coal gas current divider 3 successively; One end of mixing tube 2 is enclosed within air cyclone 4 and is connected with burner body 6, and the other end is installed flameholder 1.
During use burner is fixed on the equipment through burner fixture 5, gas pipe 7, air hose 8 are connected with the air hose supply pipe with the gas pipe supply respectively.
Further, said flameholder 1, mixing tube 2 are the high-temperature resistant anti-shock material.
Further, gas pipe 7, air hose 8 all adopt the standard connector.
The described burner of the utility model also can be done following improvement:
If possess the air preheat condition, mixing tube 2, coal gas current divider 3, air cyclone 4 to be done to regulate, combustion efficiency is better, and application is wider.
Different according to service condition, this burner can also improve at the burner fixing means, also can the method for attachment of gas pipe 7, air hose 8 be improved, to be suitable for different service condition and environments for use.
If desired, igniter interface and flame observer interface also can be set.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is left views of the utility model.
Among the figure:
1, flameholder; 2, mixing tube; 3, coal gas current divider; 4, air cyclone; 5, burner fixture; 6, burner body; 7, gas pipe; 8, air hose.
The specific embodiment
Below, with reference to the preferred embodiment of accompanying drawing detailed description the utility model.Need to prove before this; Employed term or word can not limited interpretation be common implication or the implication in the dictionary in this specification and claims, and should be based on being interpreted as implication and the notion that meets the utility model technological thought for the principle that can suitably define the notion of term with novel inventor in fact with the best mode explanation.Thereupon; The structure of representing in embodiment that this specification is put down in writing and the accompanying drawing is one of the utility model most preferred embodiment; Can not represent the technological thought of the utility model fully, therefore should be understood that for the utility model, to have various equivalents and the variation that to replace.
As shown in Figure 1, flameholder 1, mixing tube 2, coal gas current divider 3, air cyclone 4, burner fixture 5, burner body 6, gas pipe 7 air hoses 8 are formed.The supply of fuel and combustion air designs in strict accordance with the theory of combustion, make fuel and combustion air in the burning of mixing tube stable ignition, and flameholder 1 can play effective regulating action to combustion-gas flow.
The outstanding feature of this burner is independently to use the low calorie fuels blast furnace gas, and can not also can independently use under the condition of preheating at combustion air.Can expand the application of blast furnace gas so greatly, cut the waste, practice thrift operating cost.
This burner makes coal gas and air reach best proportioning and mixing through flameholder 1, mixing tube 2, coal gas current divider 3, air cyclone 4, and guarantees rational flow velocity and burning velocity relation, reaches the effect of blast furnace gas smooth combustion.
