Description
The utility model is a kind of catalytic burner.It is a kind of be the burner of fuel with the formed combustion gas after vaporizing of liquefied petroleum gas, natural gas, artificial coal gas and kerosene, diesel oil.
At present, modal burner is an atmospheric burner, and its typical structure as shown in Figure 1.It is by combustion gas nozzle 1 (there be not adjustments in the overwhelming majority and burner split, minority according to what product needed was assembled into an integral body yet), air regulating board 2, burner body 3 and fire lid 4 formations.The subject matter that atmospheric burner exists is: (1) is to same burner, obtaining the higher thermal efficiency is a pair of insoluble contradiction with pernicious gas (as the CO) content that reduces in the waste gas, this is determined by the intrinsic base reason of atmospheric burning type, thereby is difficult to realize simultaneously best separately state; (2) because the flame temperature very high (as: the highest flame temperature of artificial coal gas is near 1200 ℃, and the highest flame temperature of natural gas is above 1800 ℃) of atmospheric burning type provides condition (as NO for the generation of pernicious gas
xWhen surpassing 1100 ℃, ignition temperature just can obviously increase); (3) atmospheric burner generally all adopts copper and cast iron to constitute its structure, and these materials have very high thermal capacity, consequently cause the reduction of combustion thermal efficiency.Just because of there are the problems referred to above in atmospheric burner, so further developing of it has been subjected to restriction.The board-like burner of a kind of infrared ceramic (shown in Fig. 2 (a) and (b)) is arranged now.It is made up of combustion gas nozzle 1, air regulating board 2, mixing tube 5, burner shell 6 and ceramic wafer 7.It makes moderate progress (as improving the thermal efficiency) than atmospheric burner on some performance, can't thoroughly solve but still have problems, and comprises producing CO, HC and NO
xPernicious gas, the easy burned product obstruction of ceramic wafer mesh etc.
The utility model purpose is: the applied catalysis combustion technology, corresponding structure design is proposed, and significantly improve combustion thermal efficiency and realize energy-conservationly, reduce pernicious gas CO, NO in the burnt gas significantly
xContent with HC.
The utility model is to realize like this.It mainly is made up of combustion gas nozzle 1, air regulating board 2, nozzle support 13, nozzle locknut 12, injection increaser 11, burner shell 6, catalytic combustion plate 7, seal, sealing materials 10, anemostat 8 and screw 9,14 to propose a kind of burner structure (as shown in Figure 3, Figure 4).In this structure, anemostat 8 is fixed in burner shell 6 inside, and its circular hole one end is aimed at the circular hole of opening on burner shell 6 sidewalls; Catalytic combustion plate 7 is fixed in burner shell 6 positions suitable for reading by seal, sealing materials 10; Nozzle support 13 is fixed on injection increaser 11 contraction mouths one end, and the other end of injection increaser 11 inserts in burner shell 6 side-wall holes and makes anemostat 8 be inserted in its end; Be fixed on the nozzle support 13 with two locknuts 12 (or other fixedly positioning mode) by actual optimum state through the combustion gas nozzle 1 after the debugging; For reducing the error in manufacturing, the assembling process, guarantee mutual concentricity requirement, adopt stored energy welding to be connected (or other anti-deformation) method between burner shell 6 and the anemostat 8, whole employing non-welding connecting modes (as screw) between burner shell 6 and injection increaser 11, injection increaser 11 and the nozzle support 13.Use this structure, can give play to catalytic combustion superior function in every respect, thereby solve the technical problem that is difficult to overcome that atmospheric burner exists effectively, and can guarantee that main performance parameter reaches perfect condition.This structural design also is to have one of reason of essential difference with the board-like burner of infrared ceramic on critical performance parameters.
The utility model is obtained following effect: 1. thermal efficiency height, energy-saving effect is remarkable.Use catalytic burner, the thermal efficiency can reach 65～71.6%, can improve 10～16% than corresponding atmospheric burner, is equivalent to energy-conservation 14.3～23.3%.2. elimination pernicious gas, environment purification.Use catalytic burner, CO, HC content can descend significantly (have only 10 several PPm as CO content, reduce by 85～95%) in the flue gas than corresponding atmospheric burner.Simultaneously again since ignition temperature be controlled at and the highlyest be no more than 940 ℃, thereby destroyed NO
xBuild environment, making it content only has several PPm.Owing to energy-conservation total air consumption, the product CO after the also feasible burning of having reduced
2Reduce, reach the purpose of environment purification.3. because surface combustion is to betide several millimeters depths in the catalytic plate, thereby can guarantee to have stable fired state, have outstanding wind loading rating.4. because the thermal capacity of primary structure part is little, thermal radiation loss is few, not only helps improving the thermal efficiency but also can reduce back pressure smooth combustion state.5. there are not igniting and flame-out noise during normal combustion.6. the comparable atmospheric burner of integral burner weight reduces more than 30%.
The utility model has following characteristics: 1. selected for use capillary ceramic plate after catalyst treatment as catalytic combustion plate 7.2. under the constant situation of unit area loading, with the difference of combustion gas kind, each size assortment of the nozzle diameter of combustion gas nozzle 1 and injection increaser 11, anemostat 8 is different.(as being 7850～9498mm for catalytic combustion plate area
2Burner, when using liquefied petroleum gas as fuel, the nozzle diameter is Φ 0.60～0.95mm, injection increaser throat diameter is Φ 18～26mm, when fuel changed artificial coal gas into, above-mentioned size was respectively Φ 1.10～2.25mm and Φ 14～20mm) again.Can obtain the air-fuel ratio of broad and the best of realization combustion gas like this mixes.3. once inhale the specific (special) requirements of enough burning required airs in order to satisfy the catalytic combustion needs, increased injection increaser air inlet area and taken the circumstances into consideration to be equipped with air regulating board that (the injection increaser air inlet area maximum as near gas burner reaches 3025mm
2, and do not need air regulating board).4. in burner shell 6, increased "T"-shaped anemostat 8.Anemostat 8 is outside one's consideration except that having certain angle of flare, the also uniform aperture that has on the "T"-shaped plane, and Open Side Down during installation.This just is further uniform and stable the played important function of mixing and guaranteeing burning of air with combustion gas.5. the burner part near burning radiation and conduction scope has all adopted the little material of thermal capacity (having selected thickness≤0.8mm sheet metal for use as burner shell 6 and anemostat 8), has reduced the loss of combustion thermal efficiency.6. between burner shell 6 and the injection increaser 11, between injection increaser expander 11 and the nozzle support 13, between anemostat 8 and the burner shell 6, burner shell 6 prevents that the connected mode that part produces distortion (as is threaded with installing to have adopted between the anchor point, energy storage welding etc.), help improving the overall package precision, guarantee concentricity requirement.7. combustion gas nozzle 1 is being fixed on the nozzle support 13 after the actual debugging on the burner, makes it into as a wholely, can solve the high problem of fuel gas injection requirement concentricity effectively, is one of key that guarantees the burning various performance parameters.8. both adopted between catalytic combustion plate 7 and the burner shell 6 and can guarantee seal request, can reduce heat conducting seal, sealing materials (as cordierite powder+refractory fiber cotton) again.9. burner can not be subjected to the restriction (as can upside-down mounting using) of setting angle and position.
