Summary of the invention
The object of the present invention is to provide a kind of petal type burner, the existing burner CO of solution and the problem that the NOx discharging is large and efficiency of combustion remains further raising are to reach the national energy-saving environmental protection standard.
A kind of petal type burner provided by the invention is characterized in that this burner comprises fire hole seat, mixing chamber, pedestal, induction tunnel and nozzle, and nozzle inserts in the end of induction tunnel, and an end of the other end of induction tunnel and pedestal is connected; The pedestal other end is fixedly connected with the bottom of mixing chamber, and the fire hole seat is installed in the top of mixing chamber, is furnished with the petal type fire hole above the fire hole seat, and fire hole is regular arrangement in a circumferential direction.
As improvement of the technical scheme, the quantity of described petal type fire hole is 3～7, and the lobe number of each fire hole is 4～8.
As further improvement in the technical proposal, the outlet of described fire hole is 8～12mm. apart from the distance on fire hole seat top
As the further improvement of technique scheme, described nozzle is made of three jet pipe mouths that are positioned on the nozzle carrier at least, and the angle between the center line of each jet pipe and described induction tunnel is 5 to 9 degree.
As further improving again of technique scheme, the spacing between each fire hole is about 15mm; The height of fire hole is about 7mm; The number of fire hole is 3～6.
When the present invention worked, fuel was sprayed by nozzle, and injection portion of air (primary air) enters mixing chamber by induction tunnel under certain pressure, and auxiliary air can be carried by the injection of petal type fire hole self.(primary air refers to because the nozzle ejector action enters combustion tube by the air of nozzle ejection with fuel, and auxiliary air refers in the combustion process from additional air of surrounding air week).
The present invention adopts the petal type fire hole, and it is strong to compare common fire hole ejector capacity, and mass ratio of induced-to-inducing air is large, at fire hole rate of discharge one regularly, can entrainment more air, and gas-cooker efficient is improved, and makes heating more even, and heat absorption efficiency is higher.If general gas-fired range with vortex burner reduces the distance of the bottom of a pan and fire hole, can produce the Means of Secondary Air Supplement deficiency, incomplete combustion produces black smoke, causes inefficiency, energy waste.Adopt gas-cooker of the present invention then not have these problems, when petal fire hole and the bottom of a pan close together, CO and NOx discharging are all very low.Proof adopts gas-cooker of the present invention by experiment, and the heat absorption efficiency of pot face has reached 65%, and the CO discharge capacity is below 100ppm simultaneously, and the NOx discharge capacity is below 100ppm, well below national energy-saving environmental requirement index.
