Abstract
The utility model discloses an oxygen-rich combustion device, which comprises a fuel pipe, an oxygen supplying pipe and a heat-insulating combustion nozzle, wherein the combustion nozzle and the fuel pipe are coaxially arranged at the front end of the fuel pipe; and a fuel spray port communicated with the fuel pipe is arranged at the axial line. Oxygen spray ports are distributed on the same circumference of the combustion nozzle, wherein the same circumference has the equal distance with an outer ring of the fuel spray port; and an annular pressure-stabilizing cavity is mounted on the periphery of the fuel pipe between an oxygen spray port and the oxygen supplying pipe. A proper amount of furnace gas is sucked by oxygen flow strands before the fuel is mixed, so that the flame temperature can be reduced effectively, the flame kinetic energy can be increased and the temperature distribution in the furnace is uniform. The utility model has the advantages of improving the heat efficiency, saving energy sources, and reducing the pollution.
Description
Technical field
The utility model relates to a kind of burner, relates in particular to a kind of oxygen-enriched burning device.
Background technology
Chinese invention patent ublic specification of application CN1043376 discloses a kind of " fuel gas of band igniter and the burner of oxygen ", annular combustible gas nozzle changes in the oxygen channel by the radius of curvature parallel with axis at the diffuser end of reative cell one side, oxygen channel is with one heart round the combustible gas nozzle, high-voltage ignition cable feeds through the combustible gas passage, its end changes in the metal electrode, and be mounted to make it with combustible gas and oxygen vortex in metallic walls form a spark gap.Its goal of the invention is so long as improve the fuel gas of original igniter and the igniter of the burner of oxygen.This burner is compared with traditional air-breathing burner, is receiving certain effect aspect the raising thermal efficiency and the firing temperature.But because the comburant oxygen flame temperature is too high, cause near the scaling loss rapidly of flame zone, the burner life-span reduces.High temperature helps the generation of Nox, makes Nox content increase in the combustion product, causes environmental pollution.Main problem is: because comburant oxygen, the length of flame shortens, and because of the combustion adjuvant volume reduces, combustion product reduces, reduce the function of flame, increased the inhomogeneities of temperature field in furnace, influenced the real realization of the thermal efficiency, can not guarantee the heating quality of furnace charge, especially more outstanding for this problem of large-scale metallurgical industrial furnace.
The utility model content
The purpose of this utility model provides a kind of thermal efficiency, energy savings, minimizing of can improving and pollutes, and the oxygen-enriched burning device of long service life.
The purpose of this utility model realizes by following technical solution:
A kind of oxygen-enriched burning device comprises cartridge, oxygen supply pipe and heat insulation burner, and described burner and cartridge are coaxially set at the cartridge front end, and axial location offers the fuel nozzle ports that is connected with cartridge.Be evenly equipped with the oxygen spout on the burner with on the equidistant same circumference in fuel nozzle ports outer ring, the periphery of cartridge is equipped with annular pressure stabilizing cavity between oxygen spout and the oxygen supply pipe.
Be evenly equipped with 6-12 oxygen spout on the burner with on the equidistant same circumference in combustion gas spout outer ring, the concrete quantity of oxygen spout is relevant with fuel quantity and combustion requirements.
Have annular gaps between the fuel nozzle ports of burner and the cartridge, this annular gaps can be connected with pressure stabilizing cavity, also can be connected with the keeping pipeline of special setting.In order to form the oxygen ring, the oxygen thin layer of ejection covers fuel stream surface, creates the primary condition of burning, simultaneously, helps self flame stabilization.
The advantage that the utility model compared with prior art has is: the Oxygen Flow thigh with fuel mix before suck an amount of furnace gas, the oxygen concentration of combustion-supporting gas is controlled at below 25% or 25%, reduced flame temperature effectively, increased flame kinetic energy.Therefore, uniformity of temperature profile in the stove, thermal efficiency height, energy-saving effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of a kind of oxygen-enriched burning device of the utility model;
Fig. 2 is the left side view of Fig. 1.
Wherein: the 1-cartridge; The 2-pressure stabilizing cavity; The 3-annular gaps; 4-oxygen spout; 5-oxygen supply pipe; The heat insulation burner of 6-; The 7-fuel nozzle ports.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of oxygen-enriched burning device of the utility model comprises cartridge 1, pressure stabilizing cavity 2, oxygen supply pipe 5 and heat insulation burner 6, described burner 6 is coaxially set at cartridge 1 front end with cartridge 1, its axial location offers the fuel nozzle ports 7 that is connected with cartridge 1, has between burner spout 7 and the cartridge 1 in order to form the annular gaps 3 of oxygen ring.Be evenly equipped with 8 oxygen spouts 4 on the burner 6 with on the equidistant same circumference in combustion gas spout 7 outer rings.Between oxygen spout 4 and the oxygen supply pipe 5, cartridge 1 periphery is equipped with annular pressure stabilizing cavity 2.Fuel nozzle ports 7 is connected with pressure stabilizing cavity 2 with annular gaps 3 between the cartridge 1.
During work, fuel is confessed from the fuel nozzle ports 7 on burner 6 axis with a kind of lower speed through cartridge 1.The oxygen that oxygen supply pipe 5 provides is through pressure stabilizing cavity 2 voltage stabilizings, and the oxygen of its 90%-95% forms a high velocity stream thigh screen around center fuel stream by being evenly equipped with fuel nozzle ports 7 oxygen spout 4 ejections on every side; The oxygen of residue 5%-10% is sent by the annular gaps 3 around the fuel stream, further covers fuel.Owing between oxygen spout 4 and the fuel nozzle ports 7 enough distances are arranged, make the Oxygen Flow thigh can with fuel mix before, suck an amount of furnace gas in advance and mix and make it to form the suitable atmosphere of oxygen content, and then with burst effect of fuel stream, produce low temperature flame.By the pressure and the flow velocity of control oxygen, control the furnace gas amount that it sucks in injection, can make ignition temperature for slave mode.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
