Description
Technical field
The utility model relates to the prewarming baking equipment at industrial furnace cellar for storing things, is specifically related to a kind of fuel gas with low heat value roaster.
Background technology
When using fuel gas with low heat value to carry out prewarming baking to stove cellar for storing things, the heat that fuel gas buring produces quite a few taken away by tail gas, cause that heat utilization ratio is low, flame temperature is on the low side, because flame temperature is only a little more than the burning-point of combustion gas self, thus make fuel gas buring unstable, efficiency of combustion is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of scientific and reasonable for structure, can significantly improve the fuel gas with low heat value roaster of fuel gas buring efficiency and heat utilization ratio.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Fuel gas with low heat value roaster, comprise external jacket, oxygen enrichment orifice plate, fuel gas inlet, reducing pipe, high pressure spot lighted torch, the steady flame cone of bluff body and setting-up screw, oxygen enrichment orifice plate is fixed in external jacket and forms combustion chamber, also oxyphie layer mineral and internal jacket is provided with successively between oxygen enrichment orifice plate and external jacket, cavity is formed between internal jacket and additional cover, external jacket is provided with the evacuated joint with this cavity connects, one end of the non-undergauge of reducing pipe is communicated with fuel gas inlet, its undergauge end stretches in combustion chamber, flow deflector is provided with between the part of reducing pipe in combustion chamber and oxygen enrichment orifice plate, the barred body of high pressure spot lighted torch stretches in combustion chamber, and be fixedly connected with external jacket with internal jacket by fixed cover, the ignition tip of high pressure spot lighted torch is arranged near the undergauge end of reducing pipe, cone end and the reducing pipe of the steady flame cone of bluff body are oppositely arranged, its other end is fixedly connected with one end of setting-up screw by fixing muscle, the other end of setting-up screw is connected with the strip slide of external jacket inwall.
Thermal storage ceramic ball is filled with in the steady flame cone of above-mentioned bluff body.
The outer wall of above-mentioned external jacket is provided with mounting flange.
Compared with prior art, the utility model has the advantages that: fuel gas with low heat value roaster of the present utility model adopts curb pins inner room to form the design of vacuum chamber, greatly reduces heat loss; Adopt the design of oxyphie layer mineral to be convenient to form oxygen-rich area around it, improve the shock probability of combustion gas molecule and oxygen molecule, and then guarantee the adequacy of fuel gas buring, substantially increase the efficiency of combustion of combustion gas; Adopt the steady flame cone of bluff body to fill the design of thermal storage ceramic ball, both improve the rigidity of flame, and the temperature of combustion chamber can have been remained on the burning-point of combustion gas again, and guaranteed the continuity burning of combustion gas.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, fuel gas inlet, 2, reducing pipe, 3, external jacket, 31, evacuated joint, 4, internal jacket, 5, oxyphie layer mineral, 6, oxygen enrichment orifice plate, 7, combustion chamber, 71, flow deflector, 8, bluff body steady flame cone, 9, thermal storage ceramic ball, 10, fixing muscle, 11, high pressure spot lighted torch, 12, setting-up screw, 13, mounting flange, 14, chute.
Detailed description of the invention:
As shown in Figure 1, fuel gas with low heat value roaster, comprise external jacket 3, oxygen enrichment orifice plate 6, fuel gas inlet 1, reducing pipe 2, high pressure spot lighted torch 11, the steady flame cone 8 of bluff body and setting-up screw 12, oxygen enrichment orifice plate 6 is fixed in external jacket 3 and forms combustion chamber 7, oxyphie layer mineral 5 and internal jacket 4 is also provided with successively between oxygen enrichment orifice plate 6 and external jacket 3, cavity is formed between internal jacket 4 and additional cover 3, external jacket 3 is provided with the evacuated joint 31 with this cavity connects, one end of the non-undergauge of reducing pipe 2 is communicated with fuel gas inlet 1, its undergauge end stretches in combustion chamber 7, flow deflector 71 is provided with between the part of reducing pipe 2 in combustion chamber 7 and oxygen enrichment orifice plate 6, the barred body of high pressure spot lighted torch 11 stretches in combustion chamber 7, and be fixedly connected with external jacket 3 with internal jacket 4 by fixed cover, the ignition tip of high pressure spot lighted torch 11 is arranged near the undergauge end of reducing pipe 2, cone end and the reducing pipe 2 of the steady flame cone 8 of bluff body are oppositely arranged, its other end is fixedly connected with one end of setting-up screw 12 by fixing muscle 10, thermal storage ceramic ball 9 is filled with in the steady flame cone 8 of this bluff body, the other end of setting-up screw 12 and the strip chute 14 of external jacket 3 inwall are slidably connected, the outer wall of external jacket 3 is provided with mounting flange 13.
In above-mentioned fuel gas with low heat value roaster structural design, form cavity between its internal jacket 4 and external jacket 3, the air in cavity is extracted out by recycling evacuated joint 2, forms vacuum area, the basic free of losses of the heat energy that combustion gas is produced in combustion; Its oxyphie layer mineral 5 makes easily to form oxygen-rich area around oxygen enrichment orifice plate 6, improve the shock probability of combustion gas molecule and the oxygen molecule introduced from flow deflector 1, form inflammable mixture of gas, Thorough combustion under the effect of high pressure spot lighted torch 11, improve the efficiency of combustion of combustion gas, the oxyphie mineral of this oxyphie layer mineral can be some perofskite type oxides; The set-up mode of the steady flame cone 8 of its bluff body, make the flame be shaped in combustion chamber 7 combustion before ejection, have certain rigidity, its inside is accompanied by the thermal storage ceramic ball 9 of filling, heat can be absorbed, and then on the burning-point moderate temperature of combustion chamber 7 being remained on fuel gas with low heat value, to guarantee the continuity burning of combustion gas, because the steady flame cone 8 of this bluff body can horizontally slip by the chute along strip under the effect of setting-up screw 12, be thus convenient to the length controlling the flame sprayed from the circular passage formed between itself and oxygen enrichment orifice plate 6 according to actual conditions.
