Abstract
The invention relates to a kiln combustion structure with a carbon precipitation function, which comprises a fuel nozzle, a combustion air nozzle and a kiln body space. The combustion air nozzle consists of an upper-side oblique arch, a lower-side bottom plate and side walls on two sides of the combustion air nozzle, the fuel nozzle is arranged below the combustion air nozzle (flame of a combustor is transversely arranged), the distance from the fuel nozzle to the kiln body space ranges from 0.5 meter to 1 meter, and an included angle between the combustion air nozzle and the fuel nozzle is 14 degrees. When a kiln with the structure runs, fuel is mixed with lower-temperature combustion air which enters the kiln from a heat storage chamber, a carbon precipitation function is realized, and then the fuel enters the inside of a high-temperature kiln body of the kiln to be combusted. By the aid of the structure, uniformity of a temperature field in the kiln can be improved, radiation coefficient of combustion flame of the fuel and production quality of metallurgical auxiliary materials are enhanced, heat exchange capacity of the combustion flame and the metallurgical auxiliary materials is strengthened, and accordingly consumption of the fuel and production cost of the metallurgical auxiliary materials are lowered.
Description
Affiliated technical field
The present invention relates to a kind of have analyse carbon functional kiln burning structure, especially a kind ofly belong to the Regenerative Combustion Technology field, and be mainly used in the kiln burning structure in the metallurgic auxiliary materials heating system of cross flame metallurgic auxiliary materials tank furnace.
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 present invention be intended to propose a kind of have analyse carbon functional kiln burning structure, to solve the defective of kiln in the prior art.
Summary of the invention
The object of the present invention 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.
Technical scheme of the present invention 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, kiln of the present invention 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 burning structure of the present invention 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 invention has the beneficial effects as follows:
(1) the kiln form of the present invention's 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.
(2) the present invention adopts fuel nozzle ports to be arranged in the bottom of combustion air spout, and has certain distance (being approximately about 0.5 meter to 1 meter) from furnace space, and combustion air spout and fuel nozzle ports have certain included angle; Fuel is with after the lower combustion air of temperature mixes; Analyse the carbon process, enter into the kiln body of heater internal combustion of high-temperature then, improved the radiation coefficient of combustion flame; Reach the purpose that strengthens the Fire Radiation ability; Strengthen the heat-exchange capacity of combustion flame and metallurgic auxiliary materials, reduced the consumption of fuel, thereby reduced the production cost of metallurgic auxiliary materials.
(3) the present invention makes that kiln temperature inside field is more even owing to improved the radiation coefficient of combustion flame, thereby has improved the uniformity of metallurgic auxiliary materials fusing, has guaranteed the production of high-quality metallurgic auxiliary materials.
(4) the present invention has very strong adaptability for the combustion fuel of kiln, can be applied to fuel such as natural gas, heavy oil, diesel oil, coal gas generation gas.
