A high combustion rate burner, includes nozzle sleeve, its characterized in that: the inside blender that is equipped with of nozzle sleeve, the head of blender is located the nozzle sleeve, and the afterbody of blender is located the telescopic afterbody of the nozzle outside, the connection of after section gas fuel passag of blender, the spout is connected to the telescopic head of nozzle, air duct is connected to the telescopic afterbody lower extreme of nozzle. Comparing with prior art, providing a high combustion rate burner, gas and air send into through respective passageway that the nozzle mixes and the burning, and combustion processes accomplishes in the nozzle sleeve, and combustion product passes through the blowout of the telescopic spout of nozzle, and the jet velocity will reach 200ms.
Description
Technical field
The utility model relates to industry heating technical field, specifically a kind of high combustion rate burner.
Background technology
Current high combustion rate burner muzzle velocity is generally at 90-150m/s, and usually need to use high pressure positive blower to burner air feed, under such circumstances, not only power consumption is high, and the noise produced when running is large; Nitride in combustion product and carbon monoxide atmosphere pollution comparision contents high, larger to atmospheric pollution effect.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, there is provided a kind of high combustion rate burner, combustion gas and air are sent into burner by respective passage and are mixed combining combustion, and combustion process completes in nozzle sleeve, combustion product is sprayed by the spout of nozzle sleeve, and spouting velocity will reach 200m/s.
For achieving the above object, design a kind of high combustion rate burner, comprise nozzle sleeve, it is characterized in that: nozzle sleeve inside is provided with blender, the head of blender is positioned at nozzle sleeve, and the afterbody of blender is positioned at the lateral tail of nozzle sleeve; The afterbody of described blender connects blast tube, and the head of nozzle sleeve connects spout, and the afterbody lower end of nozzle sleeve connects air duct.
Described blender is funnel-shaped structure, and the side of blender afterbody connects flame detecting device, and the opposite side of blender afterbody connects spark plug; The inside of blender is provided with flame stabilization ring.
Described nozzle sleeve is bullet type structure.
The middle part outer rim of described nozzle sleeve is provided with adpting flange.
The utility model compared with the existing technology, there is provided a kind of high combustion rate burner, combustion gas and air are sent into burner by respective passage and are mixed combining combustion, and combustion process completes in nozzle sleeve, combustion product is sprayed by the spout of nozzle sleeve, and spouting velocity will reach 200m/s.
To be calculated by aerodynamics and the air/gas blender designed and nozzle sleeve can guarantee burner stable operation under the prerequisite of 200m/s muzzle velocity, the crushing that blender produces is little especially, make burner can support the use the blower fan of power at low pressure, operation power consumption and the sound level of burner can be reduced.

See Fig. 2 to Fig. 4,1 is blast tube, and 2 is air duct, and 3 is nozzle sleeve, and 4 is spout, and 5 is spark plug, and 6 is flame detecting device, and 7 is blender, and 8 is flame stabilization ring, and 9 is adpting flange.
Detailed description of the invention
With reference to the accompanying drawings the utility model is described further below.
As shown in Figures 1 to 4, nozzle sleeve 3 inside is provided with blender 7, and the head of blender 7 is positioned at nozzle sleeve 3, and the afterbody of blender 7 is positioned at the lateral tail of nozzle sleeve 3; The afterbody of described blender 7 connects blast tube 1, and the head of nozzle sleeve 3 connects spout 4, and the afterbody lower end of nozzle sleeve 3 connects air duct 2.
Blender 7 is in funnel-shaped structure, and the side of blender 7 afterbody connects flame detecting device 6, and the opposite side of blender 7 afterbody connects spark plug 5; The inside of blender 7 is provided with flame stabilization ring 8.
Nozzle sleeve 3 is in bullet type structure.
The middle part outer rim of nozzle sleeve 3 is provided with adpting flange 9.
High combustion rate burner is with a combustion chamber, fuel enters nozzle sleeve 3 by connecing blast tube 1, air enters nozzle sleeve 3 by air duct 2, mix in nozzle sleeve 3 while burn, substantially the realization in nozzle sleeve 3 of the mixture of air and combustion gas is burnt completely, high-temperature combustion product sprays with high speed from spout 4 by the gas combustion bulbs of pressure, and its speed is 90-150m/s; High-speed and high-temperature air-flow can to drive in stove gas at whole kiln internal circulation flow, play strong stirring action, strengthening convection heat transfer' heat-transfer by convection effect, make stove kiln temperature and atmosphere all very even, Convective Heating evenly and rapidly can be carried out to by heating target, improve the quality and yield of product, save fuel, be also conducive to simplifying kiln structure simultaneously.
Burner igniting is realized by spark plug 5, and flame detecting device 6 can be arranged on the side of blender 7 afterbody, plays the effect of blowout protection.
To be calculated by aerodynamics and the blender 7 of the air/gas designed and nozzle sleeve 3 can guarantee burner stable operation under the prerequisite of 200m/s muzzle velocity.The crushing that blender 7 produces is little especially, makes burner can support the use the blower fan of power at low pressure, can reduce operation power consumption and the sound level of burner.
Air and combustion gas mix combining combustion at blender 7 internal classification, significantly reduce flame temperature, the amount of nitrides therefore produced in combustion product low especially (below 80ppm).
Adopt the flame stabilization ring 8 of blender 7 inside to make operation that burner also can be stable when very little load.
The structure of modularized design, can require the sleeve of choice for use unlike material and different muzzle velocity: occasion serviceability temperature being no more than to 1050 degrees Celsius, can provide the sleeve using heat-resisting alloy material according to the technological temperature used; Serviceability temperature is no more than to the occasion of 1370 degrees Celsius, the sleeve using silicon carbide ceramics material can be provided; Serviceability temperature is no more than to the occasion of 1540 degrees Celsius, the sleeve of high-temperature flame-proof pouring material can be provided.
Also the sleeve of three kinds of different muzzle velocities can be selected according to the technological requirement used: 80m/s(burner with inferior speed); 150m/s(high combustion rate burner); 200m/s(ultrahigh speed burner).
