Description
Technical field
The utility model relates to the coal powder burner field, particularly relates to a kind of high-temperature boiler fuel-economizing igniter.
Background technology
Large-sized station boiler igniting and low-load combustion-stabilizing are huge with oil mass, 100MW boiler oil gun capacity 800～1000kg/h, and one time the cold start fuel consumption surpasses 30 tons, and oil price is above 90,000 yuan; 200MW boiler oil gun capacity 1200kg/h, nearly 40 tons of cold start fuel consumption, 120,000 yuan of oil prices; 300MW boiler oil gun capacity 1800kg/h, nearly 80 tons of cold start fuel consumption, 240,000 yuan of oil prices; Nearly 120 tons of cold start fuel consumption of 600MW boiler, 360,000 yuan of oil prices.
In the pulverized coal boiler ignition field, much coal burners such as little oil, plasma appear, and its common ground is to utilize localized hyperthermia's incendiary source, at burner internal classification firing coal-dust airflow, reaches igniting fuel-economizing purpose.Because high temperature dot is positioned at burner inside, increased the burner resistance on the one hand, cause easily on the other hand the slagging scorification scaling loss.There are larger difference in this type of burner and main burner in structure function, do not possess underload ability and coal adaptability under the condition of the auxiliary igniting source that do not come into operation.
The utility model content
The technical problem that the utility model mainly solves provides a kind of high-temperature boiler fuel-economizing igniter, can realize few fuel consumption and can use the colm combustion.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high-temperature boiler fuel-economizing igniter is provided, comprise: the coal feeding pipe road, be connected with one-level pulverized coal combustor and secondary pulverized coal combustor on the described coal feeding pipe road in turn, described coal feeding pipe road is outside equipped with cooling duct, be provided with multistage cooling air film between described cooling duct and the coal feeding pipe road, be provided with oil gun on the described one-level pulverized coal combustor, be connected with compressed air source on the described oil gun, described one-level coal dust firing is indoor to be provided with a plurality of little oil burners.
In preferred embodiment of the utility model, also be connected with three grades of pulverized coal combustors on the described secondary pulverized coal combustor, described secondary pulverized coal combustor and three grades of indoor auxiliary burners that are provided with of coal dust firing.
In preferred embodiment of the utility model, described little oil burner quantity is 2, and described 2 little oil burners are the diagonal angle, and to be arranged on the one-level coal dust firing indoor.
In preferred embodiment of the utility model, described oil gun is skewed and is arranged on the one-level pulverized coal combustor.
In preferred embodiment of the utility model, also be provided with the strong inspissator of coal dust in the described coal feeding pipe road.
The beneficial effects of the utility model are: the utility model high-temperature boiler fuel-economizing igniter can realize few fuel consumption and can use the colm combustion.
Description of drawings
Fig. 1 is the structural representation of the utility model high-temperature boiler fuel-economizing igniter one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, coal feeding pipe road, 2, one-level pulverized coal combustor, 3, secondary pulverized coal combustor, 4, cooling duct, 5, the cooling air film, 6, oil gun, 7, compressed air source, 8, little oil burner, 9, three grades of pulverized coal combustors, 10, auxiliary burner, 11, the strong inspissator of coal dust.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, a kind of high-temperature boiler fuel-economizing igniter, comprise: coal feeding pipe road 1, be connected with one-level pulverized coal combustor 2 and secondary pulverized coal combustor 3 on the described coal feeding pipe road 1 in turn, described coal feeding pipe road 1 is outside equipped with cooling duct 4, be provided with multistage cooling air film 5 between described cooling duct 4 and the coal feeding pipe road 1, be provided with oil gun 6 on the described one-level pulverized coal combustor 2, be connected with compressed air source 7 on the described oil gun 6, be provided with a plurality of little oil burners 8 in the described one-level pulverized coal combustor 2, cooling duct 4 is lowered the temperature by 5 pairs of coal feeding pipe roads 1 of multistage cooling air film.
In addition, also be connected with three grades of pulverized coal combustors 9 on the described secondary pulverized coal combustor 3, be provided with auxiliary burner 10 in described secondary pulverized coal combustor 3 and three grades of pulverized coal combustors 9, secondary pulverized coal combustor 3 and three grades of pulverized coal combustors 9 can make coal dust be fully burned.
In addition, described little oil burner 8 quantity are 2, and described 2 little oil burners 8 are the diagonal angle and are arranged in the one-level pulverized coal combustor 2, and micro oil is lighted by little oil burner 8 at the first pulverized coal combustor 2 interior high-intensity combustions, produce thermal-flame.This flame a small amount of coal dust that at first ignites utilizes the heat of coal dust firing self to remove the more coal dust that ignites again, and by multi-stage ignition, adopts the principle of power amplification, reaches the purpose of finally lighting a large amount of coal dusts.
In addition, described oil gun 6 is skewed and is arranged on the one-level pulverized coal combustor 2.
In addition, also be provided with the strong inspissator 11 of coal dust in the described coal feeding pipe road 1, the strong inspissator 11 of coal dust can concentrate by force by coal dust.
Be different from prior art, the utility model high-temperature boiler fuel-economizing igniter can realize few fuel consumption and can use the colm combustion.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
