As shown in Figure 1, burner includes a pipe 4, a coaxial line and is sleeved on the pipe 1 of these pipe 4 exterior circumferential and is coaxially set at the pipe 5 of pipe 4 inside, between pipe 4 and pipe 1, form an annular intake adit 11, between pipe 4 and pipe 5, form an annular fuel gas runner 12, simultaneously, form an intake adit 13 in the inside of pipe 5, and the radially inlet 3 of combustion gas passes pipe 4 and pipe 1 is connected with annular fuel gas runner 12.
One disk 8 is installed on the top of pipe 5, be evenly equipped with the short tube 9 that some and axis have certain inclination angle at these disk 8 upper edge certain diameters, form the diffused air port, utilize this short tube 9 to form and the acutangulate air-spray of axis in the front portion of intake adit 13.
On the top of pipe 1 disk 6 is installed, and be evenly equipped with some short tubes that are arranged in parallel 7 at this different diameter in disk 6 upper edges, form air port, simultaneously, top at pipe 1 is equipped with disk 10, be evenly equipped with some through holes 14 at these disk 10 upper edge certain diameters, wherein short tube 7 and 9 all extends in separately the through hole 14, and in this through hole 14, form an annular fuel gas runner 15, simultaneously, disk 10 has a through hole 16 in the middle, utilizes this annular fuel gas runner 15 and through hole 16 to form the bull fuel nozzle of combustion gas.Wherein, disk 6,8,10 plays stable flame pan.
Seal with annular wooden partition 19 in pipe 4 and the left side that is positioned at its inner pipe 5, simultaneously, the left side that is sleeved on the pipe 1 of these pipe 4 exterior circumferential at pipe 4 and coaxial line is evenly equipped with four gripper shoes 2, so that pipe 4 is fixedlyed connected with pipe 1.
Primary and secondary air proportioning adjusting device includes the semi-circular disks 17 and the hand screw adjusting device 18 that is arranged on the horizontal radial that two middle parts have semi-circular hole, and this primary and secondary air proportioning adjusting device is located at the rear side end of pipe 4 and pipe 5.
Control device adopts control circuit and the parts in the existing gas combustion apparatus, therefore, is no longer described in detail.
The operation principle of low-noise high-efficiency gas burner is in the utility model: utilize air to flow out in short tube 7 and 9, and combustion gas is flowed out in disk 10 and short tube 7 and 9 formed annular fuel gas runners 15 and through hole 16, promptly flow out successively outward from the center of disk 10 for the gas-flow of axially parallel, with the gas-flow that axially is acute angle and air stream, and axial gas-flow and air flow, utilize this gas-flow and air to mix strongly, and guarantee that combustion gas is molecular state with air and mixes at the middle part of disk 10.In addition, burner in the utility model is owing to adopt bull fuel nozzle structure, a torch is divided into several tiny torches, and part internal flame torch and burner axially are the outer acute angle of dispersing and spray, form bump and strong premixed flame, increased burning flame face and improved flame propagation velocity, from and strengthened the disturbance of burner outlet air-flow, make gas-flow different, be beneficial to mix with the velocity magnitude and the direction of air stream; And the straight spout of arranging at disk 10 middle parts of combustion gas is a through hole 16, make combustion gas in the combustion zone of high temperature, carry out the reaction of methane decomposition self carburization soon, to increase radiation intensity, reach and organize red-hot combustion product to be back to the torch root, supply with the purpose of the ignition heat of combustion gas, air mixture.
In general, realize that good burning is based on four fundamentals: promptly enough ignition temperatures, sufficient combustion air, good combustion gas mix and enough combustion reaction times with combustion air.More than 4 can design by the burner structure reasonable optimizing and realize.Be that above problem can be converted into fuel and the combustion air problem of coupling rationally that how to make fully.And the burner in the utility model has been paid attention to combustion gas in the process of mass flowing nozzle, because the effect of inertia force will be done inertia motion by original flow trace, like this, middle part at burner will form diffused flame, around burner, will form direct-injection flame, because the swabbing action in the flow process is aspirated mixing with the air of flame outside 10%～15% in direct current air intake mode, like this, on whole disk 10, form and mix splendid fuel gas, and descending fire burns in enough ignition temperatures, simultaneously, because perturbation action produces the flame recirculating zone, fuel is burnt rapidly, be equivalent to prolong combustion reaction time, improved ignition temperature, thereby realize burning rapidly and efficiently.In addition, burner in the utility model is by means of two intake adits, and flow out through the multi-head small-diameter pipe, air is mixed strongly with combustion gas, thereby form the elasticity denoising structure, thereby reduce inertial collision noise, impact noise and combustion noise to greatest extent, reach the purpose of low noise.
In sum, the low-noise high-efficiency gas burner in the utility model is owing to compare with other burner after adopting unique burner and have following exclusive characteristics:
1. burner meets hydromechanical characteristic, can produce fabulous pressure field of quality and concentration field, the combustibility curve is good, guarantee the abundant mixed combustion of gas and air, and the flame briliancy is big, increased radianting capacity, strengthened heat transfer, realized the efficient conversion of fuel and almost do not had CO generating, made burning safer, stable, efficient, fuel saving, energy-saving effect is more remarkable.
2. special structure design makes power consumption little, and operating noise is extremely low.
3. air distribution is reasonable, the air mass flow that intake adit passed through can be respectively wind flowing along interior pipe 5 and along the mobile secondary wind of outer pipe 1,4, and can realize the manual adjustments of air flow rate proportioning by the air flow rate proportioning adjusting device, make burning fully, flame stabilization, upright and outspoken strong and convergence is good, flue gas is clear smokeless, can reduce the discharge capacity of CO in the waste gas, NO greatly, meets the air management regulations of world today's strictness.
4. be applicable to the industrial furnace of various negative pressure and pressure-fired, as oil and petrochemical heating furnace, large, medium and small type boiler, heating furnaces such as metallurgy, pottery, building materials.Can satisfy mounting means such as end burning, tipburn, level burning or skew back.
5. adopt the elasticity denoising structure, reduced inertial collision noise, impact noise and combustion noise to greatest extent, reached the purpose of low noise.
In addition; above-mentionedly only a specific embodiment in the utility model is made detailed description; can not be as protection domain of the present utility model; because it is made simple change or modification is more or less freely as those skilled in the art; but this change and modification all can not break away from the design spirit in the utility model; therefore, every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should be considered to invade protection domain of the present utility model.
