The specific embodiment:
Specific embodiment one, shown in accompanying drawing 1, accompanying drawing 5, present embodiment comprises fire lid 1, burner seat 2, blower fan 3, nozzle 4, burner seat 2 is provided with air intake 5, fuel gas inlet 6, combustion gas chamber 7, air chamber 8, combustion gas chamber 7 is communicated with fuel gas inlet 6, air chamber 8 is communicated with air intake 5, blower fan 3 is installed in air intake 5 places, nozzle 4 is provided with gas port 9, air scoop 10, mixer 11, jet expansion 18, air scoop 10 is arranged on the middle part of nozzle 4, and mixer 11 is arranged between jet expansion 18 and the air scoop 10.Nozzle 4 can evenly distribute and be installed in burner seat 2 inside, and gas port 9 is communicated with combustion gas chamber 7, and air scoop 10 is communicated with air chamber 8.Burner seat 2 is provided with hybrid chamber 12, and hybrid chamber 12 is communicated with jet expansion 18.Uniform distribution plate 13 is placed between fire lid 1 and the hybrid chamber 12, and hybrid chamber 12 is divided into premix chamber 14, the even chamber 15 of pressure.The quantity of nozzle 4 can be 3～8, as three, four, five, six, seven, eight; Can be provided with 3～6 air scoops 10 on each nozzle 4, as three, four, five, six.In the present embodiment, the quantity of nozzle 4 is six, and each nozzle 4 is provided with four air scoops 10.
During use, air advances air chamber 8 by blower fan 3 drums, enter into the mixer 11 of nozzle 4 from the air intake 10 of six nozzles 4, combustion gas simultaneously enters into combustion gas chamber 7 from the fuel gas inlet 6 of burner seat 2, gas port 9 from six nozzles 4 sprays then, join at the mixer 11 of nozzle 4 with air, begin to mix, enter into premix chamber 14 then together, further mix, reach and mix, the aperture from uniform distribution plate 13 enters the even chamber 15 of pressure again, the everywhere pressure of mist in the even chamber 15 of pressure is more even, and the fire hole ejection of covering on 1 from fire is at last burnt.
The required air capacity of combustion gas completing combustion is once provided by blower fan 3, passes through a series of mixing then, and combustion gas and air reach energy clean-burning preset ratio, for example standard oil liquefied gas (C in the gaseous mixture
3H
8: 75%, C
4H
10: 25%) can be 1: 26 etc. with the ratio of air.Can provide effectively and satisfy the required air of completing combustion, make mixing of air and combustion gas, thereby it is more abundant that fuel gas buring is got, help improving the thermal efficiency.
Specific embodiment two, shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, it has increased middle internal heat lid 16, central intake pipe 17 on the basis of embodiment one, and middle internal heat lid 16 is communicated with central intake pipe 17.
During use, the air of internal heat lid 16 adopts the nature injection in entering, and combustion gas enters from central intake pipe 17, then therefrom internal heat lid 16 ejection burnings, the flame that middle internal heat is covered 16 places can kindle a fire reliably and cover the mixed air of 1 place ejection, effectively keeps the smooth combustion of fire lid 1 place combustion gas.
Middle internal heat lid 16 can be shared the portion of hot load, this moment, fiery lid 1 can suitably reduce thermic load, when outer shroud thermal transfer joint firepower, the rate of change of load just can reduce, blower fan 3 air quantity fall than also reducing simultaneously, so can be when not regulating firepower, blower fan 3 air quantity change and lag behind and cause flame blow-off or yellow flame.For example: the outer ring fire rated heat input, rated heat load of burner is 4KW, when from big heat load adjustment to little thermic load 1KW, air quantity also changes thereupon, because the characteristic of blower fan 3, the variation of air quantity can not be synchronous with load variations, so just might be transferred to the moment fire of little load and be blown out.Otherwise, transfer to moment in big when load from little load, might produce yellow flame inadequately because of air quantity.
After having increased middle internal heat lid 16, central intake pipe 17, the thermic load that middle internal heat is covered 16 places is 1KW, fire lid 1 place's thermic load is 3KW just, the flame that covers 1 place when fire from big heat load adjustment to little thermic load 1KW, load variations is 2KW only just, can reduce the phenomenon that yellow flame is blown out or produced to fire to occur.
Present embodiment moderate heat lid 1 is identical with embodiment one with operation principle with the course of work of nozzle 4, does not repeat them here.
