Abstract
The utility model discloses a flame adjustable low NOx fuel gas (fuel oil) combustor, which is composed of a fuel gas (fuel oil) gun and a three-way air register. The utility model can combuste gas fuel, the low heating value of which is more than 16000kJ/Nm< 3 >, heavy oil, light oil, residual oil, and emulsified residual oil. The utility model can be used for combusting fuel gas or fuel oil singly, and can also be used for combusting both fuel gas and fuel oil. The three-way air register is composed of an interior passage way which is provided with a firing stabilizer, a middle passage way which is provided with a cone-shaped swirler, and an exterior passage way which is provided with cone-shaped swirl vanes; the air which is supplied to be combusted is divided into smooth combustion air, main combustion air, and graded air, and the air quantities of the smooth combustion air and the graded air are regulated respectively by baffles at the air inlets of the interior and the exterior passage ways, so that stable combustion and low NOx combustion of different fuels can be realized. The cone-shaped swirler can move in axial direction; the rotational flow strength of the main combustion air is regulated and an aerodynamic field is changed to regulate the shape of flame to adapt to the combustion of different fuels and the requirements to the forms of different furnace chambers. The utility model has the characteristics of good economical efficiency and low NOx, which is proved by the cold-state aerodynamic field test, the hot-state test, and the engineering practice.
Description
Existing combustion gas, oil burner are made up of combustion gas (oil) rifle and air register usually, and gas gun has center jet gun and circumference multiple gun formula jet gun, and oil combustion gun is an intermediate arrangement, can adopt atomizing types such as steam atomization, air atomizing or mechanical atomization.Air register is used forms such as flat flow, blade adjustments formula always.Small-sized industrial boiler is generally mated the flat flow air register, do not adopt usually and reduce NO
xMeasure.
The purpose of this utility model provides a kind of novel burner, and it can fire low heat valve is 16000kJ/Nm
3Above gaseous fuel, all kinds of liquid fuels such as combustion heavy oil, light oil, residual oil and emulsification residual oil.It is adjustable to adapt to various boiler furnace form that it possesses flame profile, also has low NO simultaneously
xCombustion characteristics, decapacitation are disposed at outside all kinds of combustion gas, the oil burning boiler, are specially adapted to various coal furnaces and transform combustion gas (oil) stove as, and satisfy the environmental requirement of Air Pollutant Emission.This burner can be independent combustion gas or fuel oil, also not only combustion gas but also fuel oil.
In order to achieve the above object, the technical measures of the utility model employing are: combustion gas (oil) rifle is arranged in the burner middle part.Air register is the triple channel form, in the concentric circles mode combustion air is passed through internal channel, center-aisle and three passages of outer tunnel respectively, and internal channel is steady combustion wind, and center-aisle is main burning wind, and outer tunnel is a classification wind.Regulate steady combustion wind and classification wind air quantity and wind rate by baffle plate, with smooth combustion and the low NO that adapts to each class A fuel A
xRequirement, center-aisle is by main burning wind, its swirl strength is adjustable, to regulate the requirement that aerodynamic field and flame profile adapt to different fuel and different burner hearth forms.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the low NO of the utility model flame adjustable type
xCombustion gas (oil) burner sketch
Below accompanying drawing is further described.
The described burner of Fig. 1 is formed fuel supplying part spare by multiple gun formula gas gun (6) center arrangement oil combustion gun or gas gun (7), gas gun goes out gaseous fuel by the aperture high velocity jet of end, oil combustion gun can be steam atomization formula, air atomizing formula and mechanical atomization formula, determines its atomizing type and determines its atomization angle according to the burner hearth form of being joined according to different fuel oil type (light oil, heavy oil, residual oil or emulsification residual oil).Burner is combustion gas separately when only adorning multiple gun formula gas gun or the single gas gun in center, also can only adorn the independent fuel oil of center oil combustion gun, also can install multiple gun formula gas gun and center oil combustion gun not only combustion gas but also fuel oil simultaneously.The supply of combustion air is by triple channel air register (8): internal channel is that vane type stabilizer (1) that mat is loaded on channel end obtains rotational flow air and supplies with the fuel gun root and make its form recirculating zone and come smooth combustion, the kind difference of based on fuel is supplied with different steady combustion air quantity; Center-aisle mat swirl cone (2), make main burning wind produce eddy flow by passage, this cyclone can move axially along the burner center line, when outwards (anti-burner hearth direction) is mobile, produce the gap between the passageway cone outer wall that swirl cone and its taper match, part air direct current from the gap passes through, make main burning wind by eddy flow and the two mixing ejection of direct current, different proportion by the two air quantity, make main burning wind obtain different swirl strengths, and in burner hearth, form different aerodynamic fields and form different flame profiles when burning, adapt to different fuel and different burner hearth forms; Outer tunnel be the taper swirl vane (3) in the mat passage make classification wind with less air quantity and certain eddy flow and fuel lag behind mixes and reduce discharge fume in NO
xGenerate.The air quantity of steady combustion wind is adjusted by the baffle plate (4) of internal channel wind inlet place device, and classification wind air quantity is adjusted by the baffle plate (5) of outer tunnel wind inlet place device.It is adjusted that the swirl strength of main burning wind then moves axially swirl cone by pull bar (9).Plate washer and pull bar are all operated with being contained in the external transmission mechanism of burner casing.Burner put into operation debugging suitable after, the baffle plate of inside and outside passage and the position of swirl cone can be fixed, in service as no special circumstances then needn't be regulated.
Example is burnt in test and examination:
Draw by burner air register cold test, steady combustion wind wind rate can be regulated in the 0-18% scope, classification wind wind rate can be regulated in the 0-25% scope, the swirl strength of main burning wind can be regulated in the 0.44-0.76 scope, adjusting along with each wind, make the recirculating zone, center of air-flow and air-flow range and air-flow angle of flare all adjustable, the symmetry of air-flow is good.
Hot examination is burnt and is carried out on the 6t/h boiler, and combustion light oil, distributive value are 380kg/h.When excess air was 1.05-1.08, burning had good and economic, NO in the exhaust fully
xDischarge capacity is at 70mg/Nm
3Below, reach environmental requirement.Draw by the combustion test of burner in unrestricted space, the shape of flame is the flame extended corner and the length of flame, and very big adjustable range is all arranged.
The 10t/h that this burner successfully is applied to Daqing oil field fires on the industrial oil oven and the large-scale oil burning boiler of 325MW of emulsification residual oil.
