The specific embodiment
Below in conjunction with accompanying drawing double-firerings ong-fire slot turbulent burner is described in further detail:
This burner has the induction tunnel 9 of two air inlets on burner body 1, they are communicated with outer ring cavity 5 and inner annular cavity 6 respectively, and hollow joint hole 8 and central through hole 7 are arranged.Correspondence is covered with give vent to anger the greatly ring cowling 2 and the ring cowling 3 of giving vent to anger for a short time respectively two toroidal cavity upper ends.Ring baffle 4 is all arranged at the top of toroidal cavity 5 and inner annular cavity 6 outside, and toroidal cavity is divided into upper and lower two chambeies that communicate, and ring baffle 4 one side end edges connect the outer wall of cavity, and ventilation annular distance 12 is arranged between other end limit and the cavity inner wall.The ring cowling 2 upper edge circumference of giving vent to anger greatly are evenly distributed with out air cleft 10, and the ring cowling 3 upper edge circumference of giving vent to anger for a short time are evenly distributed with out air cleft 11.As Fig. 2 and shown in Figure 4, going out air cleft 10 and going out air cleft 11 is to make the ring cowling of giving vent to anger with corrosion resistant plate, and stamps out the strip crack simultaneously on request, and the rectangular fritter of the steel plate that tears apart becomes the skewed oblique sidewall of air cleft that forms; Fig. 3 and shown in Figure 5 and for example, going out air cleft 10 and going out air cleft 11 is that to process the two side on the ring cowling made from copper material of giving vent to anger be the strip R-joining that tilts; The former is easy than latter's processing and manufacturing.The cone angle of ring cowling 2 of giving vent to anger greatly is bigger than the angle numerical value of the cone angle beta that goes out compression ring 3 for a short time.Cone angle is 1 with the ratio scope of cone angle beta angle numerical value: (0.7～0.9).The length dimension that goes out air cleft 10 is 1 with the ratio scope of the length dimension that goes out air cleft 11: (0.6～1), the gap of giving vent to anger (promptly the stitching wide) gross area that goes out air cleft 10 is 1 with the ratio scope that goes out the gap of giving vent to anger (promptly the stitching wide) gross area of air cleft 11: (0.4～0.8).
According to the user heat power of gas burner size there are different requirements, enumerate the technical scheme of two different technologies parameter proportionings below.
Example 1, the burner that firepower is bigger.Give vent to anger greatly 125 millimeters of ring cowling 2 external diameter φ, cone angle is a hexagonal angle, being evenly distributed with out air cleft 10 along the ring cowling circumference has 30, give vent to anger 0.9 millimeter in gap (promptly stitching wide) of long 11～12 millimeters of seam, seam; For a short time give vent to anger 70 millimeters of ring cowling 3 external diameter φ, cone angle beta is 98 ° of angles, has 21 along the ring cowling circumference air cleft 11 that evenly distributes, give vent to anger 0.9 millimeter in gap (promptly stitching wide) of long 11～12 millimeters of seam, seam.The ratio of give vent to anger the gap gross area and the gap gross area of giving vent to anger that goes out air cleft 11 that goes out air cleft 10 was with 1: 0.7.The length dimension that goes out air cleft 10 was selected for use 1: 1 with the ratio of the length dimension that goes out air cleft 11.This burner is large and small give vent to anger ring cowling 2,3 and on it to go out that air cleft 10,11 is with thickness be that 0.5 millimeter corrosion resistant plate punching press is made, going out air cleft is to go out the crack at the steel plate correspondence position, steel plate is torn going out the air cleft position, little rectangular become (with respect to the normal slope of this place's taper seat) tearing out forms air cleft one sidewall slope.This burner is bigger because of the total burning area of the large and small ring cowling of giving vent to anger, and firepower is stronger, is applicable to that the more family of population uses.
Example 2, the burner that firepower is more moderate.Give vent to anger greatly 105 millimeters of ring cowling 2 external diameter φ, cone angle is 112 ° of angles, going out air cleft 10 has 26, give vent to anger 0.9 millimeter in gap of long 14 millimeters of seam, seam; For a short time give vent to anger 50 millimeters of ring cowling 3 external diameter φ, cone angle beta is 98 ° of angles, the gap gross area of giving vent to anger that goes out air cleft 10 was selected for use 1: 0.44 with the ratio of the gap gross area of giving vent to anger that goes out air cleft 11.The length dimension that goes out air cleft 10 was selected for use 1: 0.7 with the ratio of the length dimension that goes out air cleft 11.The large and small ring cowling of giving vent to anger of this burner is selected the copper material manufacturing for use.Go out air cleft and be on the large and small ring cowling 2,3 of giving vent to anger, to process strip R-joining＜with respect to this place's conical surface normal slope 〉, the two side that forms seam tilts.To go out the total burning area of compression ring little, more moderate than precedent because of large and small for this burner, and firepower is moderate.Be applicable to that the less family of population (as three mouthfuls of people～four-hole people's family) uses, and saves combustion gas than precedent.
Combustion gas enters two induction tunnels 9 through the burner body inlet and flows into outer ring cavity 5 and inner annular cavity 6 respectively during use, the combustion gas of band impulsive force is limited in baffle plate cavity of resorption eddy flow by ring baffle 4 in the chamber, the burned body lumen wall of impulsive force absorbs, the combustion gas that becomes more evenly to flow is flowed out from going out air cleft again, it is even that each bar goes out air cleft outflow combustion gas, it is even respectively to go out air cleft flame when making burning, can not producing gives vent to anger, and to cover certain zone bigger because of combustion gas impulsive force influence discharge and pressure, combustion flame skewness and influence use.Central through hole 7 and hollow joint hole 8 are ring cowling eddy flow fire and the additional auxiliary air usefulness of outer ring cowling eddy flow fire in being respectively, for guaranteeing that fuel gas buring provides essential condition fully.
