Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, the air stove of a kind of Automated condtrol of the present invention, including cylinder 1, the burner 2 of being located at described cylinder 1 front end, described cylinder 1 is circular tube structure, this avoid flue gas circulation dead angle and the unequal situation of thermo parameters method；Center Gas Pipe 3 and airduct 4 it is respectively equipped with in described burner 2, described center Gas Pipe 3 is arranged on the top of described airduct 4, described center Gas Pipe 3 and airduct 4 all extend in described cylinder 1, described airduct 4 is tilted is provided with mixed wind sheet 5, wherein, described mixed wind sheet 5 is 30 degree with the angle of horizontal direction, in the present embodiment, 30 degree are changed to by traditional 25 degree, simultaneously, outlet sheet in center Gas Pipe 3 has the hoop hole of a diameter of 8mm, so effectively strengthen the mixing intensity of combustion gas and air feed and reduce incorporation time, thus increase combustion stability, avoid the fire extinguishing phenomenon that fuel gas with low heat value often occurs；It addition, the special construction design of above-mentioned burner 2 makes burner outlet jet velocity high, premix uniformly, can overcome the shortcomings such as the flame instability because causing containing tar, impurity, liquid hydrocarbon etc. in combustion gas, coking, blocking；Being provided with U-shaped furnace wall 6 in described cylinder 1, the middle section position of described U-shaped furnace wall 6 is provided with U-shaped bulge-structure 7, so effectively strengthens flue gas degree of filling in air stove, it is ensured that the uniform temperature fields in stove is so that fuel gas with low heat value burning is more stable；The rear side of described U-shaped bulge-structure 7 is provided with mixed wind system, described mixed wind system use peripheral hardware annular passage 8, in set radial nozzles 9 structure, so can mix with rotation type backflow wind and form air curtain structure, thus reduce the flowing velocity of front end flue gas, upset the normal flow channel of flue gas, form strong flue gas mixed flow region, decrease the space used by flue gas mixing.Testing through reality, needed for former single tube mixes wind structure, passage length is more than 800mm, and the air curtain structure after improvement has only to 350mm；The rear end of described U-shaped bulge-structure 7 is provided with mixed flow region 10, in the present embodiment, owing to mixed flow region is cut off with burner by the design of U-shaped furnace wall structure, decreases mixed flow region and makes burning more reliable and more stable the impact of combustion zone.
Concrete, described burner 2 uses two-stage ignition mode, i.e. uses high energy ignition unit directly to light combustion-supporting fuel again by combustion-supporting ignited fuel main fuel, it is ensured that it is safe and reliable that fuel gas with low heat value is lighted a fire；It is provided with fire defector mechanism 11 on described burner 2, so can reflect timely and process furnace flame signal, it is ensured that the safety of combustion process.
Concrete, it is provided with flame peephole 12 at the flame concentration of described cylinder 1, described cylinder 1 is provided with first order temperature sensor 13, so passes through flame peephole 12 and can observe, grasp combustion conditions and the thermo parameters method situation of combustible gas in stove clearly；Passback state modulator burner aerator wind supply quantity according to first order temperature sensor.
Concrete, the normalizing face, inner side of described U-shaped furnace wall 6 uses high-temperature flame-proof wear-resistant castable, the back of the body fire face, outside of described U-shaped furnace wall 6 uses light thermal-insulation pouring material, in guarantee stove, so while flameholding, reduce again the outside wall temperature of cylinder, through measuring and calculating outside wall temperature less than 50 DEG C, the loss of air stove integral heat sink is 1-2%.
Concrete, the rear end of described mixed wind system is provided with second level temperature sensor 14, returns state modulator recirculating air volume according to second level temperature sensor, it is achieved Automated condtrol, and the automatic stabilisation that air stove is effectively ensured is run.
It should be understood that the fire defector mechanism 11 of the present invention and existing flame detecting device are without essential distinction, therefore do not say in detail at this.
In sum, this air stove collection burns and mixes wind structural integrity, saves space and strengthens the mixed wind effect of dehydrator reduced air and high-temperature hot-air, can make air stove constant air outlet temperature, uses Automated condtrol, it is ensured that the automatic stabilisation of air stove is run.
The above is only the better embodiment of the present invention, therefore all equivalence changes done according to structure, feature and the principle described in present patent application scope or modification, in the range of being all included in present patent application.
