Abstract
The utility model relates to a honeycomb thermal storage style burner tip, which is mainly used in all kinds of metallurgical industry furnace taking top gas as fuel. The utility model includes a burner tip (9), a baffle bricks (12) and a honeycomb (13) respectively equipped at front and back of the burner tip (9). The utility model is characterized in that the head part of the burner tip is equipped with a burner side connecting with a flange (6), and the lateral face of the burner tip is equipped with a burner fission flange (11). The utility model can connect the burner tip with furnace body not directly, and can reuse 80% of the honeycomb in the rear end of burner tip.
Description
Technical field:
The utility model relates to a kind of burner, especially relates to a kind of honeycomb ceramics heat-accumulating burner, is mainly used in blast furnace gas is used for various metallurgical industrial furnaces.Belong to metallurgical heat power engineering field.
Background technology:
Because the day of the metallurgical energy is becoming tight, and utilizes regenerative combustion technology in recent years, with the byproduct of blast furnace ironmaking---the example that blast furnace gas is used for various metallurgical industrial furnaces gets more and more.Particularly applying on heater for rolling steel saved a large amount of high-grade energy media for vast smelter, and it is can effect remarkable to fall this section.No matter adopt which kind of regenerative combustion technology, still there are many problems in actual use.
Present honeycomb ceramics heat-accumulating burner uses main two problems that exist on heater for rolling steel:
1, the honeycomb ceramics heat-accumulating burner of form generally links to each other with the body of heater side wall at present, and the burner head is imbedded furnace wall.Because thermal coefficient of expansion is inconsistent between burner body and the furnace wall, causes the fracture of burner body easily, thereby cause the body of heater lateral surface to leak fire, leakage coal gas, burner is not long service life, must destroy furnace wall when changing burner, cause stove short service life, and workload is big during maintenance.
2, the honeycomb ceramics heat-accumulating burner of present form is after use a period of time (being generally 6 to 9 months), anterior baffle plate brick and the part heat storage obstruction that can be graded by the ash in the furnace gas in the burner, thereby influence the burning capacity of burner, must change baffle plate brick or honeycomb ceramics anterior in the burner, and the honeycomb ceramics at rear portion is excellent, can continue to use.Must remove honeycomb ceramics whole in the burner and baffle plate brick when the baffle plate brick of the honeycomb ceramics heat-accumulating burner of present form front portion in changing burner or honeycomb ceramics, because honeycomb ceramics is relatively more fragile, it is broken serious to remove the back, generally can not reuse, thus the honeycomb ceramics loss that causes burner rear portion about 80% to reuse.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and burner directly can be connected with body of heater, and can reuse the honeycomb ceramics heat-accumulating burner of about 80% honeycomb ceramics in burner rear portion.
The purpose of this utility model is achieved in that a kind of honeycomb ceramics heat-accumulating burner, comprise: the burner body, forward and backward baffle plate brick and the honeycomb ceramics of being provided with in the burner body, it is characterized in that: described burner body head is provided with burner side adpting flange, and the side is provided with burner split flange.
The utility model honeycomb ceramics heat-accumulating burner is installed the back and is not all directly linked to each other with refractory material with furnace binding, the different mutual shearings that cause of swell increment guarantee that body of heater and burner body can use more muchly in the time of can eliminating between body of heater and burner because of high temperature well.
The utility model honeycomb ceramics heat-accumulating burner does not directly connect because independent with body of heater, can with burner as a whole spare part change and do not influence the anti-material of body of heater, can improve body of heater service life, reduce the engineering time.
The utility model honeycomb ceramics heat-accumulating burner connects with burner split flange at the burner body side surface, and the burner body is synthetic by two parts.Baffle plate brick and honeycomb ceramics when using first in the burner body are installed by the rear portion.To be usedly surpass 6 months, find that the burner gas throughput obviously descends after, the burner split flange of burner body side surface is untied, change baffle plate brick and honeycomb ceramics that the front portion in the mouth body has been stopped up, lock burner split flange then, burner can normally use.The honeycomb ceramics of 80% in the mouth body is prolonged more than one times service life.
Description of drawings:
Fig. 1 is the utility model honeycomb ceramics heat-accumulating burner general structure schematic diagram.
Among the figure: furnace wall burner block 1, spout passage 2, refractory fibre containing zirconium 3, furnace wall 4, furnace wall side adpting flange 5, burner side adpting flange 6, pyrographite filler 7, lightweight not Lay stone is watered material feeding 8, burner body 9, lightening casting material 10, burner split flange 11, baffle plate brick 12, honeycomb ceramics 13, burner construction bolt 14.
The specific embodiment:
Referring to Fig. 1, the utility model honeycomb ceramics heat-accumulating burner mainly is made up of burner body 9, baffle plate brick 12, honeycomb ceramics 13, burner side adpting flange 6 and burner split flange 11.
The utility model honeycomb ceramics heat-accumulating burner can separate construction with body of heater when installing, treat body of heater construct finish after the same with the traditional burner again honeycomb ceramics heat-accumulating burner of installing, needn't be the same with existing heat-accumulating burner, installation must be finished before furnace wall is poured into a mould.By design attitude the furnace wall burner block 1 of burner correspondence is built furnace wall 4 during installation, furnace wall side adpting flange 5 is installed in the installation site, 5 of furnace wall burner block 1 and furnace wall side adpting flanges with refractory fibre containing zirconium 3 liners, with the burner integral installation to furnace wall 4, be connected with furnace wall side adpting flange 5 with burner construction bolt 14, guarantee burner head and furnace wall burner block 1 good bond.
Burner side adpting flange 6 does not link to each other with burner body 9 before burner is installed, after treating that burner is in place, in the space of 1 of burner body 9 and furnace wall burner block, fill refractory fibre containing zirconium 3, fill with pyrographite filler 7 between burner side adpting flange 6 and the furnace wall side adpting flange 5, locking back burner side adpting flange 6 and 9 welding of burner body are finished the installation of burner.
Consider that baffle plate brick anterior in the utility model honeycomb ceramics heat-accumulating burner 12 and 13 general service lifes of honeycomb ceramics only are 6 to 9 months, the utility model honeycomb ceramics heat-accumulating burner connects with burner split flange 11 in burner body 9 sides, burner body 9 (comprise liner lightweight not Lay stone water material feeding 8 and lightening casting material 10) is synthetic by two parts, and middle the filling with pyrographite filler 7 guarantees sealing.
