Description
Technical field
The utility model relates to a kind of novel coke oven gas burner.
Background technology
At present, coke oven heating system Main Function is to pit kiln conveying and regulates heating coal gas and air, and discharges exhaust gases after combustion.Rich gas refers to the coal gas that coke oven heating calorific value is high, as coke-oven gas etc.Low-grade gas refers to the coal gas that coke oven heating calorific value is low, as blast furnace gas, producer gas and mixed gas etc.Because coke-oven gas is important high-grade fuel, coke oven heating fuel should use coke-oven gas as far as possible less, multiplex low-grade gas.Steel Complex's coke-oven plant's coke oven generally adopts blast furnace (BF) gas heating, but blast furnace staying or blast furnace gas cannot be supplied to coke oven when breaking down, need in the case to adopt coke-oven gas heating, therefore modern coke oven generally adopts rich gas heating and low-grade gas to heat two cover systems.Calorific value due to low-grade gas is low (generally at 3100-3300kJ/Nm
3, mixed gas is at 4180kJ/Nm
3), coke oven adopts low-grade gas heating, is generally difficult to the end flue temperature of guarantee 1100 DEG C, especially more cannot ensures after furnace wall is impaired.
Utility model content
The purpose of this utility model solves the deficiencies in the prior art, provides one can guarantee when rich gas heating system does not work, and uses low-grade gas heating still can guarantee that the end flue temperature of combustion chamber reaches the novel coke oven gas burner of production standard.
The technical solution adopted in the utility model is: a kind of novel coke oven gas burner, comprise main pipeline, also comprise rich coke oven gas pipe, described rich coke oven gas pipe has two, be respectively equipped with the two ends up and down of main pipeline, be provided with air-flow block in described rich coke oven gas pipe mouth, the height of described air-flow block for the width of air-flow block described in 1/2 ~ 3/4 of rich coke oven gas pipe cross-sectional height be 1/2 ~ 3/4 of rich coke oven gas pipe cross-sectional width; Described main pipeline and rich coke oven gas pipe all adopt bilayer structure, and internal layer adopts silica brick, and outer employing high alumina brick, adopts fissure of displacement structure between described ectonexine.
As further improvement of the utility model, the described fissure of displacement is arranged symmetrically with combustion chamber medullary ray.
Further improve as of the present utility model, described air-flow block is highiy refractory brick.
The beneficial effect that the utility model adopts is: the utility model is by the situation of burner heat supply deficiency during increase rich gas pipeline solution coke oven combustion low-grade gas, simultaneously according to air current flow principle in coke oven, air-flow block is set, in order to adjust distribution of air flow amount, make more coal gas, air flow burner quirk, thus reach the object promoting burner quirk temperature of combustion, to reach process stipulation requirement; Bilayer structure resistance to thermal shocks is good, although by the brick high alumina brick of fire door, it is different from the adjacent silica brick coefficient of expansion, but solved by the design of the fissure of displacement, thus improve the uniformity ratio of end flue temperature and ensure that the homogeneity of full furnace temperature, ensure that burner coke and full oven coke uniformly ripening, improve the coke oven life-span.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 main pipeline, 2 rich coke oven gas pipes, 3 air-flow blocks.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, a kind of novel coke oven gas burner, comprise main pipeline 1, also comprise rich coke oven gas pipe 2, described rich coke oven gas pipe has two, be located at the two ends up and down of main pipeline 1 respectively, in described rich coke oven gas pipe 2 mouthfuls, be provided with air-flow block 3, the height of described air-flow block 3 for the width of air-flow block 3 described in 1/2 ~ 3/4 of rich coke oven gas pipe 2 cross-sectional height be 1/2 ~ 3/4 of rich coke oven gas pipe 2 cross-sectional width; Described main pipeline 1 and rich coke oven gas pipe 2 all adopt bilayer structure, and internal layer adopts silica brick, and outer employing high alumina brick, adopts fissure of displacement structure between described ectonexine.
By increasing by two rich coke oven gas pipes, thus the situation of burner heat supply deficiency when solving coke oven combustion low-grade gas.According to air current flow principle in coke oven, air-flow block is set in rich coke oven gas pipe, in order to adjust distribution of air flow amount, makes more coal gas, air flow burner quirk, thus reach the object promoting burner quirk temperature of combustion.For making burner quirk be adjusted to suitable temperature, the position of air-flow block in bottom flue and sectional area size are very important.According to test of many times, air-flow block apart from pipeline opening 50 centimetres, its highly for cross-section of pipeline height 2/3, width is 3/4 the best of cross-section of pipeline width.Certainly, also according to the temperature variation of burner quirk, position and the height of air-flow block can be regulated, make burner fire path temperature reach requirement.Bilayer structure resistance to thermal shocks is good, although by the brick high alumina brick of fire door, it is different from the adjacent silica brick coefficient of expansion, solves this problem by the design of the fissure of displacement, thus improves the uniformity ratio of end flue temperature and ensure that the homogeneity of full furnace temperature.The fissure of displacement is arranged symmetrically with combustion chamber medullary ray, and not only can solve the problem brought because the coefficient of expansion is different in bilayer structure, also improve bulk strength, the uniformity ratio improving end flue temperature ensure that the homogeneity of temperature.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection domain of the present utility model.
