Fig. 1 shows the structure of this oil-gas two-way type burner, comprising: oil gun 3, centre wind and natural gas line 13, combustion air air channel 15, natural gas adapter 4, combustion air adapter 7 and centre wind adapter 9; Wherein, oil gun 3 is positioned on burner axis, and oil gun 3 skin is followed successively by centre wind and natural gas line 13 and combustion air air channel 15; Oil gun 3 latter end is provided with fuel atomizer 23, fuel atomizer 23 connects fuel pipe 2 and compressed air hose 1, and shower nozzle 17 is established in oil gun 3 front end; Natural gas adapter 4 pipeline section arranges pneumatic control valve 5, and natural gas adapter 4 is vertical with oil gun 3; Centre wind adapter 9 inlet tube central axis is in combustion air adapter 7, centre wind is the shunting wind of combustion air, combustion air adapter 7 and centre wind adapter 9 arrange expansion joint (i.e. combustion air adapter expansion joint 6 and centre wind adapter expansion joint 10) and electric control valve (i.e. combustion air electric control valve 8 and centre wind electric control valve 11) respectively, and combustion air adapter 7 is vertical with oil gun 3 with the outlet of centre wind adapter 9; On centre wind pipeline 12 wall, pressure detecting point 19 is established in perforate, and on centre wind and natural gas line 13 wall, pressure detecting point 20 is established in perforate; The baffling portion that combustion air air channel 15 is connected with combustion air adapter 7 establishes voltage stabilizing bellows 14, establishes cyclone 22 in combustion air air channel 15, and cyclone is made up of one group of circumferentially evenly distributed blade, blade quantity 12 ~ 26; On the wall of combustion air air channel 15, pressure detecting point 21 is established in perforate, centre wind and natural gas line 13, combustion air air channel 15 and the same axis of oil gun, and two front ends, air channel are gradual-enlargement type; Burner connects with refractory material that incinerator is built by laying bricks or stones 18, and bearing manages blue 16.
The use procedure of the utility model oil-gas two-way type burner is as follows:
The effect of oil gun 3 is atomized and sprays fuel oil.Oil gun 3 is arranged in the position, axis of whole burner.The coaxial circles tubular structure that centre wind and natural gas line 13, combustion air air channel 15 are all identical with oil gun 3 axis.Oil gun 3 end establishes fuel atomizer 23, and fuel atomizer 23 is venturi type, and arrival end sprays into compressed air, more than air pressure 0.4MPa, and throat sprays into fuel oil, and diffuser forms the high velocity air carrying fuel particles, and droplet diameter can reach below 100um.Alloy material that oil gun 3 shower nozzle material selection is high temperature resistant, anti abrasive, nozzle configuration is according to the installation site on incinerator and the length of flame, diametric requirements and select single hole, porous, square, oval etc.
The effect of natural gas adapter 4 sprays into natural gas, natural gas adapter 4 established pneumatic control valve 5; When natural gas is sole fuel, aperture and the furnace temperature logic of natural gas pneumatic control valve 5 are chain; When firing oil and gas two kinds of fuel and sharing, a certain fuel need be set as main combustion thing.When needs improve burner rating, the control and regulation valve preferential answering on the corresponding pipeline of main combustion thing; When needs reduce burner rating, the control and regulation valve preferential answering on the corresponding pipeline of non-master combustion thing.Natural gas enters centre wind and natural gas air channel 13 along the direction perpendicular to burner axis, forms turbulent flow, and fully mixes with centre wind immediately, ensures to burn efficiently.
Centre wind enters incinerator through centre wind adapter 9 and centre wind pipeline 12; Centre wind adapter 9 is arranged effective damping, the expansion joint 10 preventing equipment to be out of shape and electric control valve 11.The aperture of control valve 11 and fuel flow rate and combustion air electric control valve 8 logic chain.Centre wind enters centre wind pipeline 12 along the direction perpendicular to burner axis, forms turbulent flow, plays the effect of cooling oil gun 3 while improving efficiency of combustion.Centre wind mixes with it before fuel fire, can prevent fuel from occurring pyrolytic.Centre wind and natural gas air channel 13 port are gradual-enlargement type, and outlet is provided with segmentation ring, are conducive to expansion and the segmentation of flame, and reduce corrosion and the wearing and tearing of shower nozzle and burner periphery refractory material.
Combustion air enters incinerator through combustion air adapter 7 and combustion air air channel 15; Combustion air adapter 7 is arranged effective damping, the expansion joint 6 preventing equipment to be out of shape and electric control valve 8; The aperture of control valve 8 and fuel flow rate and centre wind electric control valve 11 logic chain.The baffling portion that combustion air adapter 7 is connected with combustion air air channel 15 establishes voltage stabilizing bellows 14, avoids blast wandering to cause flame to fluctuate.In combustion air air channel 15, arrange cyclone 22, cyclone 22 is made up of one group of circumferentially evenly distributed blade, and blade quantity 12 ~ 26, by arranging direction and the quantity of blade, can determine the swirl strength of combustion air flexibly.
Centre wind and combustion air derive from same blower fan air feed, and compared to arranging, two blower fans are rationally more economical; The flow of centre wind and combustion air is determined by the flow of fuel; The utility model preferred burn coefficient of excess air is 1.1 ~ 1.5, and preferred center wind is 10% ~ 25% of combustion air flow.Centre wind and combustion air and fuel form fractional combustion.Centre wind part ensures rational hypoxemia primary combustion, reduces burned flame temperature, suppresses the generation of NOx, carries out the air distribution of flame root simultaneously, suppresses the precipitation of carbon black.The flame that combustion air ring-type is formed around primary combustion, supplements the air capacity needed for abundant second-time burning, and combustion air turbulent flow mixes with burning limit, main flame limit, and carry out oxygen-enriched combusting, ensure that fuel burns, heat energy is fully utilized.
Centre wind pipeline 12, centre wind and natural gas line 13 and combustion-supporting air channel 15 arrange pressure detecting point, and whether each level air-distribution of convenient observation is stablized, and is the safeguard of later stage operation and maintenance.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
