Abstract
The utility model relates to a ceramic combustor for internal-combustion hot blast stove, composed of a combustion head (1) mixing two kinds of combustion medium (the air and the flammable gas), a central channel (2) connected with and under the combustion head (1) and a set of gas channels (3, 4, ) on the two sides of the central channel (2), and two or more than two of the angles formed by the central channel (2) and the gas channels (3, 4,) are different. The mixing mode of the flammable gas and the air is processed in separated levels, a part of the flammable gas and the air are fully and homogenously mixed at the nozzle, a stable high-temperature smoke refluxing region is formed at the top of the combustor to realize stable ignition, and the rest of the flammable gas and the air are fully mixed at an altitude higher than the combustor to achieve a suitable flame region, removing the combustion vibration and the combustion flame's entrance into checker bricks because the high-temperature region is concentrated at the lower part.
Description
Affiliated technical field
The utility model relates to a kind of burner, is applicable to the mixed combustion of combustion medium, particularly is used for the ceramic burner of internal combustion stove.
Background technology
The internal combustion stove ceramic burner adopts long flame burner usually, and two kinds of combustion mediums (air and fuel gas) enter combustion chamber mixed combustion through the passage of certain angle.The angle of fuel gas and air duct is the important step of ceramic burner design, and it plays key effect to the stability of burning and the completeness of burning, and then to having a direct impact the serviceability and the service life of burner and hot-blast stove.
Fuel gas and air fluid angle are big, and then the two mixes fully, and coefficient of excess air is little, the ignition temperature height, and correspondingly combustion flame is short, and the position, high-temperature region is low, and the high-temperature flue gas amount of circling round is big, and igniting is stable.But when combustion intensity strengthens, very easily cause combustion shock, burner and hot-blast stove masonry are caused very big destruction, thereby influence the normal use of hot-blast stove, the service life of having reduced burner and hot-blast stove.In the actual production,, suitably reduce fuel gas and air fluid angle, make combustion flame elongated, move on the high-temperature region, to guarantee flameholding for avoiding the generation of this situation.Because the high-temperature flue gas amount of circling round reduces, igniting is stable inadequately first; Simultaneously since fuel gas mix with air abundant inadequately, often can not completing combustion, even flame zone entered regenerator lattice brick, causes checker brick corrode, breakage in the bags, the duct obstruction influences the result of use of hot-blast stove; Improve coefficient of excess air, help gas, but ignition temperature reduces the reduction of blast furnace feeding wind-warm syndrome in bags completing combustion.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of appropriate fuel gas and the burner of air duct angle structure, has both satisfied the requirement that mixing is abundant, igniting is stable of air and fuel gas, can obtain suitable flame region again.
Technical solution of the present utility model is: a kind of stratified combustion device, by the combustion head that mixes two kinds of combustion mediums (air and fuel gas) and below combustion head coupled central passage and one group of gas passage of central passage both sides form, the angle that central passage and gas passage constitute has two or more inequality, and the angle that central passage and gas passage constitute is less than 90 °.Combustion head can be that refractory brick builds by laying bricks or stones, and also can be to pour into by watering material feeding.
The beneficial effects of the utility model are: because the gas passage of central gas and both sides has two or more angles inequality, fuel gas and Air mixing mode are carried out by different level, can adjust the mixability of air and fuel gas flexibly to different hot-blast stoves.Part fuel gas and air that angle is big fully mix at the spout place, form a stable high temperature gases recirculating district at the burner top and play the stable ignition effect, the part fuel gas that all the other angles are little and air certain altitude above burner fully mix, obtain suitable flame region, make gas the bags fully, smooth combustion, eliminated the high-temperature region and concentrated on the phenomenon that combustion shock that the bottom causes and combustion flame enter checker brick.

Among the figure 1, combustion head, 2, central passage, 3,4 ... gas passage.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
One group of gas passage 3,4 of combustion head 1 below and central passage 2 and central passage 2 both sides ... be connected, gas passage 3,4 ... form angle α with central passage 2, β ... angle α, β ... have more than two and two inequality, from central passage 2 or gas passage 3,4 ... the ejection air with from gas passage 3,4 ... or the fuel gas of central passage 2 ejections mixes.
Claims (3)
1, a kind of stratified combustion device, reach the central passage (2) coupled and one group of gas passage (3,4 of central passage (2) both sides by the combustion head (1) that mixes two kinds of combustion mediums (air and fuel gas) in combustion head (1) below ...) form, it is characterized in that central passage (2) and gas passage (3,4 ...) angle that constitutes has two or more inequality.
2, a kind of stratified combustion device as claimed in claim 1 is characterized in that central passage (2) and gas passage (3,4 ...) angle that constitutes is less than 90 °.
