Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Knowable to Fig. 1, Fig. 2, a kind of low NOx oil and gas combination burner of this utility model, by brazier brick, main body 3, adjust wind butterfly Valve 4, regulator 5, altar lamp 6, oil gas associating rifle 7 and auxiliary air gun 8 form.Brazier brick is divided into large and small fire pot, little brazier brick 2 Being positioned on the little fire pot seat board 3-18 of main body 3, the quirk entrance flue of little brazier brick 2, upper inside wall becomes the conical surface, entrance and Band enlarging reducing between inwall;Big brazier brick 1 split becomes inside and outside circle two parts, and inner ring is that quirk entrance becomes cylinder with quirk top, Band enlarging reducing between entrance and inwall, outer ring is positioned on the mounting flange 3-2 admittedly enclosing 3-1 outside big fire pot, and regulator 5 is fixed on On main body base plate 3-12, oil gas associating rifle 7 is inserted in the sleeve pipe of regulator, and auxiliary air gun is arranged on main body base plate 3-12, long Bright lamp 6 is inserted in altar lamp sleeve pipe 3-13, uses portable electronic fire rod or artificial torch to light.
As can be seen from Figure 3, oil gas associating rifle 7 includes center air gun 7-2 and oil gun 7-1, and center air gun is hollow sleeve tubular type gas Rifle, the shower nozzle of center air gun is provided with primary fuel spray orifice, and shower nozzle is tightly connected with internal and external casing by screw thread or welding, and oil gun is inserted Also clamping in the air gun inner sleeve of center, oil gun nozzle uses internal-mixing steam atomization nozzle.As can be seen from Figure 4, auxiliary air gun 8 is adopted By the structure of gas bag 8-4 band branch gun barrel 8-3, branch's gun barrel is generally 4 or more than 4, and auxiliary shower nozzle 8-1 is provided with two grades of combustions Material spray orifice, is locked by locking nut 8-2 and branch gun barrel 8-3.
When this utility model is installed, being fixed on body of heater by main body 3-2 flange, altar lamp 6 uses portable electronic point Lighted torch or artificial torch are lighted.First light altar lamp, then by altar lamp point gas gun or the two-stage sparking mode of oil combustion gun, be suitable for In hot-air forced ventilation and cold air gravity-flow ventilation operating condition, mix operating mode, fuel pressure at single fire gas condition, single fire oil or oil gas Under the complex environment such as power, change of component, can stably burn, reach NO efficient, energy-conservation, lowXDisposal of pollutants and the ring of low noise Protect purpose.
During this utility model runs, combustion air preheats through device high-temperature flue gas waste heat recovery, and hot-air enters adjusts wind Butterfly valve, according to payload, adjusts wind Handle of butterfly valve to control total blast volume by operation, and hot-air enters burner body inner chamber, logical Excessive brazier brick 1 inner ring and little brazier brick 2 and big brazier brick outer ring and inner ring, it is achieved that the air classification of burner, force one wind Account for the 80% of total blast volume, supplied with endoporus by big brazier brick 1 inner ring, little brazier brick 2 gap, according to the order of supply, force one wind Be also divided into first and second give wind, be First air by the air feed of little brazier brick 2 endoporus, by big brazier brick 1 inner ring, little brazier brick 2 The air feed in gap is secondary wind, and light breeze accounts for the 20% of total blast volume, by big brazier brick outer ring with interior ring gap in flame upper part Section supply;Air classification is that the ultralow NOx combustion of burner tissue creates conditions.The entrance center, device fuel gas one tunnel that pipeline comes Air gun internal and external casing, sprays from central gas gun sprayer, and a road enters the gas bag of auxiliary air gun, sprays from the auxiliary shower nozzle in branch's gun barrel front end Go out, achieved the classification of burner fuel gas by central gas gun sprayer fuel jet orifice, auxiliary shower nozzle fuel jet orifice;The sky of classification Gas and combustion gas mixing, reach the purpose of strengthening mixing;Force one wind is the burning of expense equivalent proportion with the mixed combustion of fuel, produces reduction Property flue gas, with light breeze mixed combustion produce oxidisability flue gas, sectional combustion reduces combustion flame surface temperature, has controlled cigarette The generation of NOx in gas, its discharge flue gas concentration single fire gas time at below 100mg/Nm3, during single fire oil 180mg/Nm3 with Under, reach the purpose of oil and gas combination burner low NOx drainage.
