Description
Technical field
The present invention relates to burner, and in particular to a kind of low calorific value coal gasification coal gas combustion with low NOx and steady combustion function
Burner.
Background technology
Global energy is in short supply in recent years, and environmental pollution is increasingly serious.China's energy resource structure is " many coals, few oil, deficency ", because
This, China future source of energy consumption structure is still based on fire coal.Coal gasification is with coal or coal tar as raw material, with oxygen (air, richness
Oxygen or pure oxygen), vapor or hydrogen etc. make gasifying agent, under the high temperature conditions by chemical reaction by the flammable portion in coal or coal tar
Divide the process for being converted into gaseous fuel or downstream raw material.The calorific value of gas that coal gasification is produced is relatively low, difficulty of catching fire and flameholding
Property poor, therefore the flame-out problem of generally existing during burning use.
Therefore the steady combustion of low-heat value gas is a key issue for needing to solve.Auxiliary combustion is a feasible skill
Art, can using explosive fuel as auxiliary thermal source, low-heat value gas is carried out it is combustion-supporting, so as to ensure the stable combustion of low-heat value gas
Burn.In addition, in burner adding the technology of porous media to be gradually taken seriously.Multi-hole medium combustion technology is to utilize inertia
Porous media material replaces free space, and using which, for gas, powerful heat accumulation function and radiation characteristic much is realized
Thermal feedback, the waste heat in the heat and tail gas of generation of will burning are used for the premixed gas of reacting by heating area upstream, strengthen flame
In heat and mass transfer process so that combustion reaction is greatly enhanced.Porous media combustor has that power is big, scope is adjustable, high
Power density, extremely low CO and NOXThe advantages of discharge capacity, safety and stability burning, compact conformation.Hence with multi-hole medium combustion
The characteristics of technology, it is applied there are certain potentiality in low calorific value coal gasification gas-fired.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of high combustion efficiency, good stability,
The low low calorific value coal gasification gas burner with low NOx and steady combustion function of pollutant emission.
The purpose of the present invention is by following technical solution completing.It is of the present invention this with low NOx and steady
Combustion function low calorific value coal gasification gas burner, mainly including gas piping, reducer pipe, combustor, gas uniform distributor,
Porous media, air line and natural gas fired rifle；Described gas piping is coaxially connected with combustor by reducer pipe, burning
Interior is from left to right followed successively by gas uniform distributor, porous media, is provided with accordingly towards axial direction and inclines on the tube wall of combustor
Oblique air line, air line are coaxially set in outside natural gas fired rifle.
Further, the present invention is arranged circumferentially the air line described in 4, air line and combustor along combustor
Central axis angle is 45 °.
Further, the material selection refractory metal or alloy of gas uniform distributor of the present invention, is square grid
Grid structure.
Further, the material selection yttria-base zirconium oxide of porous media of the present invention, average pore size is 3-
5mm, porosity are 75-85%, and the sortord in hole is straight-through.
Beneficial effects of the present invention are：
1st, the present invention adopts assisted combustion techniques, and the heat for producing that burnt using explosive fuel lights low-heat value gas, from
And can guarantee that the stable burning of low-heat value gas；
2nd, the present invention adopt multi-hole medium combustion technology, with power it is big, scope is adjustable, high power density, extremely low CO
And NOXThe advantages of discharge capacity, safety and stability burning, compact conformation；
3rd, the present invention is except the coal gasification coal gas that can burn, can be with lower heat of combustion gas or gaseous fuel inferior, such as
Blast furnace gas, can be widely used in metallurgy, chemical industry, energy industry, with larger Social and economic benef@.

Specific embodiment
Below by specific embodiment, the present invention is further elaborated, and embodiment will facilitate a better understanding of this
It is bright, but the present invention is not limited only to following embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention includes gas piping 1, reducer pipe 2, combustor 3, gas uniform distributor
4th, porous media 5, air line 6, natural gas fired rifle 7.Gas piping 1 is connected by reducer pipe 2 is coaxial with combustor 3, fires
Burn in room 3 and be from left to right followed successively by gas uniform distributor 4, porous media 5, on the tube wall of combustor 3, be provided with court accordingly
Axially inclined air line 6, air line 6 are coaxially set in outside natural gas fired rifle 3.4 are arranged circumferentially along combustor 3
Individual air line 6, air line 6 and 3 central axis angle of combustor are 45 °.The material selection high temperature resistant of gas uniform distributor 4
Metal or alloy, is square cell structure.The material selection yttria-base zirconium oxide of porous media 5, average pore size is 3-5mm,
Porosity is 75-85%, and the sortord in hole is straight-through.
Natural gas fired rifle 7 be present invention employs as assisted combustion techniques, burning torch fuel is inflammable natural gas, profit
The heat for producing that burnt with explosive fuel directly washes away lights low-heat value gas, so as to can guarantee that the stable combustion of low-heat value gas
Burn.
The gas uniform distributor 4 of square cell structure is employed in the combustor 3 of the present invention, air-flow is played preferably
Evenly distribute effect.Porous media 5 is adopted in combustor 3 also, when gas passes through porous media 5, porous media 5 plays accumulation of heat
The effect of body, the gas of process can preferably be preheated and be burnt, with higher gas combustion efficiency.On the other hand, by
Maximum temperature can be kept low, reduce NO by the uniformity of temperature profile in the porous mediaXGeneration.
The course of work of the present invention is as follows：
Burner is first lighted a fire with natural gas fired rifle 3, is then passed through coal gasification coal from gas piping 1, air line 2 respectively
Gas, air.The flame ignition that coal gas, air are produced by natural gas fired rifle 3 in combustor 4.The flue gas produced after lighting is passed through
Gas uniform distributor 5 enters porous media 6 after evenly distributing, using the accumulation of heat structure of porous media 6, so as to ensure gas
Mixing and stable burning.After flameholding, ignition air gun 7 is closed, completely by coal gasification gas-fired.
When underload coal gas voluntarily stably can not burn, natural gas fired rifle 3 can be put into, using circumferential four natural gass
The flame impingement coal gas of burning torch 3, so that it is guaranteed that stable burn.
In addition to the implementation, the present invention can also have other embodiment.All employing equivalents or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
