Technical field
The invention belongs to cooking apparatus, relate in particular to household gas utensils.
Background technology
Domestic gas-cooker more early uses DC burner, and fire hole comparatively disperses, and combustion flame is difficult fully to be mixed with auxiliary air, causes efficiency of combustion to descend, and CO and NOx discharge capacity height can make the kitchen range decrease in efficiency in the flue gas, waste energy.What present domestic application or gas-cooker newly developed generally adopted is turbulent burner, though turbulent burner can utilize the swirl injection principle to produce stable inward turning flame combustion, the smoke mixture of combustion gas simultaneously can have reasonable the mixing with auxiliary air, the space but efficiency of combustion also improves a lot, CO and NOx are bigger in the fume emission simultaneously.If the location arrangements of cyclone fire hole is unreasonable, then the content of CO can sharply rise in the flue gas.The main flow eddy flow gas-cooker efficient of being sold in the market is all about 53%.
Summary of the invention
The invention provides a kind of burner that is used for gas kitchen ranges, solution has turbulent burner CO now and NOx discharges problem big and that efficiency of combustion remains further raising, to reach national energy-conserving and environment-protective standard.
A kind of burner that is used for gas kitchen ranges of the present invention comprises nozzle, induction tunnel, pedestal, and nozzle inserts in the induction tunnel, and induction tunnel and pedestal are connected, and it is characterized in that:
Described pedestal top is the different cylindrical shape of diameter, and diameter changes part and has dividing plate, and the pedestal space of dividing plate below constitutes mixing chamber, has the combustion tube by the equally distributed N of circumference on the dividing plate, and radius of a circle is 50～70mm, N=4～10; Described combustion tube is the hollow circular tube of top closure, and its lower end is communicated with mixing chamber, and the combustion tube top has conical protrusions, and combustion tube tip side mask has the rectangle fire hole, and its direction is outside along described radius of a circle.
Described burner is characterized in that:
Described combustion tube internal diameter is 8～14mm, and described rectangle fire hole is 240 °～300 ° at the pairing angle of circumference of combustion tube cylinder circumference upper shed; The outlet of rectangle fire hole is apart from combustion tube top 3～5mm, apart from dividing plate 50～70mm.
Described burner is characterized in that:
The bigger cylindrical side of described pedestal upper diameter has along the equally distributed air admission hole of circumference; The cylindrical shape upper support that described diameter is bigger has the cumulative circle of reverse frustoconic, and cumulative circle upper inner is evenly distributed with the bearing of placing pan.
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 replenished by pedestal top air admission hole.The fuel of process premix and AIR MIXTURES are through the cylindrical channel of N combustion tube, top rectangle fire hole ejection by cylindrical channel, combustion tube nose-circle tapered protrusion, can improve gas flow, play the water conservancy diversion effect, can around the rectangle fire hole of pedestal top, the cumulative circle be set simultaneously, with windproof heat-collecting and energy-saving.
Rectangle fire hole centralized arrangement of the present invention, firepower is comparatively concentrated, make gas-cooker power bigger, simultaneously because combustion tube reduces the distance of the bottom of a pan and rectangle fire hole, the distance in the burning main region and the bottom of a pan is shortened, increased the time of contact of high-temperature flue gas and pot face, reduce energy loss, make heating more even, heat absorption efficiency is higher.If general eddy flow gas-cooker 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 rectangle fire hole and the bottom of a pan close together, CO and NOx discharging are all very low, around the rectangle fire hole, increase the cumulative circle simultaneously, reduce the high-temperature flue gas radiation, make the interior temperature of cumulative circle higher, reduced CO and NOx discharging in the flue gas.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 requires index well below national energy-conserving and environment-protective below 100ppm.
