In figure: 1-large air-cooled center composite burner nozzle; 2-central burner nozzle protection wind beam; The combustion-supporting airduct of 3-central burner nozzle; The combustion-supporting air-valve of 4-central burner nozzle; 5-central burner nozzle gas valve; 6-central burner nozzle gas pipe; 7-protection up room of wind; 8-protection wind downstream chamber; 9-air-cooled base; 10-air-cooled base dividing plate; 11-protection wind dividing plate; 12-central burner nozzle housing; 13-refractory materials; 14-brunched burner nozzle; 15-heat-resisting top board.
Embodiment
The embodiment provided below in conjunction with Fig. 1 is further elaborated the utility model, but embodiment does not form any restriction to the utility model.
A kind of large air-cooled center composite burner nozzle 1 for roasting shaft kiln, see the combustion-supporting airduct of central burner nozzle in Fig. 1, figure 3, central burner nozzle gas pipe 6, air-cooled base 9, central burner nozzle housing 12, brunched burner nozzle 14 and heat-resisting top board 15.
Air-cooled base 9 is placed in bottom combined type burner 1; All centering burner protection wind beam 2 is inner for the combustion-supporting airduct 3 of central burner nozzle and central burner nozzle gas pipe 6; Air-cooled base dividing plate 10 is placed in the middle of air-cooled base 9, and air-cooled base dividing plate 10 upper end is provided with protection wind dividing plate 11; Protection wind dividing plate 11 left and right sides is protection wind downstream chamber 8 and the protection up room 7 of wind respectively; Central burner nozzle protection wind beam 2 is placed in air-cooled base 9 left and right sides; Brunched burner nozzle 14 is placed in four orientation of combined type burner 1.
Further, roasting shaft kiln outer bottom is respectively equipped with the combustion-supporting air-valve 4 of central burner nozzle and central burner nozzle gas valve 5.
Further, central burner nozzle housing 12 is placed in the burner cavity left and right sides; Refractory materials is provided with outside central burner nozzle housing 12.
Further, brunched burner nozzle 14 is provided with 4.
Further, the combustion-supporting air-valve 4 of central burner nozzle is provided with 4.
Further, central burner nozzle gas valve 5 is provided with 4.
Utility model works process is as follows:
Combustion air is sent on the right side of the air-cooled base 9 of large air-cooled center composite burner nozzle 1 by central burner nozzle protection wind beam 2; again from bottom to top through the protection up room 7 of wind; arrive under heat-resisting top board 15; downwards catadioptric again; by protection wind downstream chamber 8; enter on the left of air-cooled base 9, then delivered to outside the stove of left side by Left-side center burner protection wind beam 2, this completes the air-cooled protection of central burner nozzle.A part for these hot combustion airs, through the combustion-supporting airduct of central burner nozzle 3 and the combustion-supporting air-valve 4 of central burner nozzle, feeds large air-cooled center composite burner nozzle 1, then participates in burning through brunched burner nozzle 14.The hot combustion air of another part then continues upwards to carry, and is respectively used to each furnace wall side burner.
Coal gas is through central burner nozzle gas pipe 6 and central burner nozzle gas valve 5, enter large air-cooled center composite burner nozzle 1, then realize burning through brunched burner nozzle 14, powerful controlled central hot air-flow is provided, problem that the common shaft furnace central gas stream of thorough solution is not enough, and the burning of all directions all can independently regulate.
Coal gas, the combustion air of the brunched burner nozzle 14 in four orientation of large air-cooled center composite burner nozzle 1 all can independently control, and gas stream in the stove are distributed and uniformity of temperature profile is reasonable and controllable precise.
Because air flow method is even, and mix with hot cooling air, uniformity of temperature profile, and can accurately control, the burning focal area that there will not be temperature too high or cold zone, avoid burning and raw burn.
This combined type burner is heat-resisting, wear-resisting, shock-resistant, and reliable operation, the life-span is long.Both cooling performance was further improved, again the total combustion air of simultaneously preheating.
Those skilled in the art do not depart from essence of the present utility model and spirit, kinds of schemes can be had to realize the present invention, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model specification sheetss and accompanying drawing content are done, is all contained within interest field of the present utility model.
