Abstract
The utility model relates to a kiln combustion structure with a carbon precipitation function, which comprises a fuel nozzle, a combustion-supporting wind nozzle and a kiln body space, wherein the combustion-supporting wind nozzle is composed of an upper inclined arch, a lower bottom plate and side walls on two sides; the fuel nozzle is arranged on the lower edge (burner flame is distributed by cross flame) of the combustion-supporting wind nozzle and is 0.5-1m far away from the kiln body; and an inclined angle of 14 degree is formed between the combustion-supporting wind nozzle and the fuel nozzle. When the kiln adopting the structure is operated, fuel is mixed with low-temperature combustion-supporting wind entering from a regenerative chamber to generate a carbon precipitation process, and then the mixture enters a high-temperature kiln body to burn. According to the structure, the evenness of the internal temperature field of the kiln can be improved, the radiation coefficient of fuel combustion flame is improved, the production quality of metallurgy auxiliary materials is improved, and the thermal exchange capability of the combustion flame and the metallurgy auxiliary materials is enhanced so as to lower fuel consumption and the production cost of the metallurgy auxiliary materials.

Background technology
Metallurgic auxiliary materials is to produce the high-quality necessary raw material of steel at present, and high-quality metallurgic auxiliary materials can improve the quality of steel, produces high-quality metallurgic auxiliary materials and then must depend on the outstanding kiln of performance.Kiln temperature inside field has decisive for the production of metallurgic auxiliary materials; Kiln is the second largest power consumption industry that is only second to boiler at present simultaneously; In recent years, along with the appearance of national energy-conserving and environment-protective relevant laws and regulations, and the rising steadily of fuel price; How to improve the combustibility of fuel, become an advanced problems in the burning industry.
Dissimilar kilns is also adopted in the production of present domestic metallurgic auxiliary materials, but from the situation of present application, dissimilar kilns; Because its internal temperature field is also inhomogeneous; And the quality of the metallurgic auxiliary materials that causes producing is not high, simultaneously because the radiation coefficient of kiln combustion flame is not high, thereby has caused the radianting capacity of combustion flame not strong; Reduce the heat-exchange capacity of combustion flame and metallurgic auxiliary materials, and then caused the increase of energy consumption.Finally, cause the increase of cost.In view of the situation, the utility model be intended to propose a kind of have analyse carbon functional kiln burning structure, to solve the defective of kiln in the prior art.
The utility model content
The purpose of the utility model is to provide a kind of furnace construction that can improve kiln temperature inside field uniformity; To improve the production quality of fuel combustion flame radiation coefficient and metallurgic auxiliary materials; Strengthen the heat-exchange capacity of combustion flame and metallurgic auxiliary materials; Thereby reduce the consumption of fuel and the production cost of metallurgic auxiliary materials, and then solve problems such as the energy consumption that exists in existing furnace construction metallurgic auxiliary materials quality high, that produce is low.
The technical scheme of the utility model is achieved in that to have for this analyses carbon functional kiln burning structure, and according to the requirement of kiln burning to combustion flame, flame will have certain rigid, and directionality will be got well, and it is big that the flame coverage rate is wanted; The length of flame that forms is suitable, and can adjust according to the production needs.
Therefore, the kiln of the utility model adopts the unit kiln structure, and unitary space structure of inner formation can make full use of the inner unitary space of kiln like this, makes that the fusing of metallurgic auxiliary materials is effectively guaranteed.This kiln burning structure; Comprise fuel nozzle ports, combustion air spout, furnace space; The combustion air spout is made up of the oblique arch of top, the base plate of below and the side wall of both sides; Fuel nozzle ports is arranged in the bottom of combustion air spout, and has certain distance from furnace space, has oblique arch and base plate angle between combustion air spout and the fuel nozzle ports.
In addition, tiltedly arch has an oblique arch angle of declination b, and base plate has a base plate angle of declination c, and tiltedly the size of arch and base plate angle is 5 °～20 °, is preferably 14 °; Fuel nozzle ports is 0.5 meter～1 meter apart from furnace space.
Adopt its combustion fuel of kiln of the utility model burning structure can adopt fuel such as natural gas, heavy oil, diesel oil, coal gas generation gas, burner flame adopts cross flame to arrange.When kiln moves; Fuel is analysed the carbon process with after the lower combustion air of temperature that gets into from regenerator mixes, and enters into the kiln body of heater internal combustion of high-temperature then; The carbon of separating out in its combustion process has increased the flame radiation coefficient, reaches the purpose that strengthens the Fire Radiation ability.The flame that this kiln burning structure form produces fuel combustion obtains the available heat exchange with inner metallurgic auxiliary materials, has strengthened the heat exchange effect, has guaranteed the uniformity of kiln internal temperature field, has reduced the consumption of fuel simultaneously.
The beneficial effect of the utility model is:
(1) the kiln form of the utility model employing is a unit structural form, and unitary space structure of inner formation can make full use of the inner unitary space of kiln like this, makes that the fusing of metallurgic auxiliary materials is effectively guaranteed.
