Along with the enforcement of the strategy of sustainable development and country are to the pay attention to day by day of environmental protection, the elimination as Air Pollutant Discharge NOx CO mentions agenda.Low NOx control technology feasible on gas burner mainly contains: lean burn technology, grading combustion technology, flame cooling body interpositioning, reduction thermal intensity of fire port technology, fire hole optimisation technique, radiant combustion technology, pulse combustion technology etc.The utility model is intended to develop a kind of burner fire lid with fire hole horizontal bias fit structure, by the deep or light adjustment of flame, improves efficiency of combustion, to reduce the discharge of NOx, CO.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of burner fire lid with fire hole horizontal bias fit structure.
Foregoing invention object of the present utility model is realized by following scheme:
There is the burner fire lid of fire hole horizontal bias fit structure, its sidewall has the fire hole on some inside and outside surfaces, fire hole comprises the light fire hole that dense fire hole and sectional area are less than dense fire hole, some dense fire hole adjacent spaces arrange and form dense fire hole group, some light fire hole adjacent spaces arrange and form light fire hole group, and some dense fire hole groups and some light fire hole group staggering arrange and is covered with burner fire lid sidewall.
Further, dense fire hole and light fire hole cross section are circle.
Further, the central point of all dense fire holes and light fire hole is all positioned at same plane.
Further, the central point equi-spaced apart arrangement of all dense fire holes and light fire hole.
Further, burner fire lid sidewall has the frusto-conical portion shunk from bottom to top.
Further, burner fire lid upper end has pressure flame portion, and pressure flame portion upwards expands from burner fire lid sidewall frusto-conical portion minimum diameter position the pressure flame shade that formation covers burner fire lid sidewall frusto-conical portion outer rim completely.
Further, dense fire hole and light fire hole to be positioned on burner fire lid sidewall frusto-conical portion and to be positioned at below pressure flame shade.
Further, dense fire hole and light fire hole are obliquely installed, horizontal by 35 ± 5 ° of inclination angles.
Further, the stable flame hole that sectional area is less than light fire hole is also provided with below dense fire hole group.
Further, each dense fire hole shape is identical, and each light fire hole shape is identical, and the ratio of the fire hole number of each adjacent dense fire hole group and light fire hole group is 1:1 ~ 1.5, and the ratio of the dense fire hole group gross area and the light fire hole group gross area is 1:1 ~ 1.5.
The beneficial effects of the utility model are: concentrated on by bias combustion on a fire hole circle, namely on some fire hole of a fire hole circle, dense burning is carried out, and other fire hole carrying out light burning, dense fire hole and light fire hole are alternately distributed, thus realize bias combustion.The thick/thin fire hole of this novel burner is separated by layout, and dense burning and light burning are reported to the leadship after accomplishing a task and arranged, and bias combustion is complementary, reasonable layout auxiliary air, strengthens auxiliary air gettering ability, reduces fire hole circle temperature simultaneously, make it burn more abundant, effectively reduce NOx, CO discharge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is the structural representation that the utility model is arranged on burner.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail:
Shown in accompanying drawing 1, Fig. 2 and Fig. 3, the burner fire lid 3 with fire hole horizontal bias fit structure of the present utility model, its sidewall has the fire hole 1 on some inside and outside surfaces, fire hole comprises the light fire hole 1-2-1 that dense fire hole 1-1-1 and sectional area are less than dense fire hole, some dense fire hole adjacent spaces arrange and form dense fire hole group 1-1, some light fire hole adjacent spaces arrange formation light fire hole group 1-2, some dense fire hole group 1-1 and some light fire hole group 1-2 and are crisscross arranged and are covered with burner fire lid 3 sidewall.
For ease of processing, dense fire hole 1-1-1 and light fire hole 1-2-1 cross section are circle.The central point of the present embodiment all dense fire hole 1-1-1 and light fire hole 1-2-1 is all positioned at same plane.For improving combustion stability, the central point equi-spaced apart arrangement of all dense fire hole 1-1-1 and light fire hole 1-2-1.Burner fire lid 3 sidewall of the present embodiment has the frusto-conical portion shunk from bottom to top.Burner fire lid 3 upper end has pressure flame portion, and pressure flame portion upwards expands from burner fire lid sidewall frusto-conical portion minimum diameter position the pressure flame shade 2 that formation covers burner fire lid sidewall frusto-conical portion outer rim completely.Dense fire hole 1-1-1 and light fire hole 1-2-1 to be positioned on burner fire lid sidewall frusto-conical portion and to be positioned at below pressure flame shade 2.Dense fire hole 1-1-1 and light fire hole 1-2-1 is obliquely installed, horizontal by 35 ± 5 ° of inclination angles.
