Through the micro oil ignition pulverized coal burning device, the amount of oil of the oil gun can be reduced for ignition, and nonflammable meager coal and anthracite can also be ignited.
Description
Technical field
The utility model relates to a kind of tiny-oil ignition coal powder burner.
Background technology
The few-oil ignition coal powder burner, major part all is to utilize the burner cylindrical shell itself to concentrate pulverized coal ignition at present, Pulverized Coal Concentration efficient is on the low side relatively, so the ignition oil amount is relatively large.Light a fire more with difficulty for meager coal, anthracite, overall fuel-saving efficiency is lower.
The utility model content
The purpose of this utility model is, a kind of tiny-oil ignition coal powder burner is provided, and few-oil ignition coal powder burner thickening efficiency is lower, the igniting wind speed is excessive, ignition oil is bigger, especially uses the problem of meager coal, anthracite combustion weak effect to solve.
By tiny-oil ignition coal powder burner of the present utility model, it comprises burner cylindrical shell and oil gun, it is characterized in that, this tiny-oil ignition coal powder burner also comprises the pipeline inspissator, described pipeline inspissator links to each other with burner is simplified, described pipeline inspissator is designed for breeze airflow is carried out deep or light separation, is respectively the burner cylindrical shell thick coal culm air-flow and the thin powdered coal air-flow that go out through concentrating and separating is provided.
Preferably, the burner cylindrical shell is designed to double pipe structure, wherein, interior pipe preferably with outer coaxial tube be arranged on the inside of outer tube.
Preferably, described pipeline inspissator is designed to elbow structure, be used for breeze airflow is carried out deep or light separation, one end of elbow structure is that the other end of breeze airflow inlet and elbow structure branches into two outlets, wherein, outlet is positioned at the radially outer position of elbow and is connected with pipe, pipe provides the thick coal culm that goes out through concentrating and separating air-flow in being used to, and another outlet is positioned at the radially inner position of elbow and be connected with outer tube, is used to the toroidal cavity between outer tube and the interior pipe that the thin powdered coal that goes out through concentrating and separating air-flow is provided.
Preferably, described oil gun inserts along the breeze airflow direction in the interior pipe of burner cylindrical shell, and the angle α of the interior tubular axis line of oil gun axis and burner cylindrical shell is 0 °≤α≤90 °.
Preferably, described oil gun is designed to mechanical atomization oil gun, air atomizing oil gun or gasification oil gun.Also can adopt other forms of oil gun.
In tiny-oil ignition coal powder burner of the present utility model, improve Pulverized Coal Concentration effect and oil-saving effect by the said structure feature, because of coal dust is highly concentrated, and the igniting wind speed reduces greatly, light so can reduce the oil mass of oil gun, also can light for meager coal, the anthracite of difficulty combustion.
Description of drawings
Below in conjunction with accompanying drawing to being described in detail, to provide other features and advantages of the utility model according to embodiment of the present utility model.In the accompanying drawing:
Fig. 1 is the structural representation by the tiny-oil ignition coal powder burner of an embodiment of the present utility model.
The specific embodiment
Fig. 1 shows the structural representation by the tiny-oil ignition coal powder burner of an embodiment of the present utility model.
The tiny-oil ignition coal powder burner comprises burner cylindrical shell 1, oil gun 2 and pipeline inspissator 3.Pipeline inspissator 3 links to each other with burner cylindrical shell 1, and pipeline inspissator 3 is designed for breeze airflow f is carried out deep or light separation, and the thick coal culm air-flow f1 and the thin powdered coal air-flow f2 that go out through concentrating and separating are provided for burner cylindrical shell 1.Burner cylindrical shell 1 is designed to double pipe structure, and wherein, interior pipe 11 is arranged on the inside of outer tube 12, and preferably interior pipe 11 and outer tube 12 are arranged on the inside of outer tube 12 coaxially.
According to an embodiment of the present utility model, pipeline inspissator 2 is designed to elbow structure, be used for breeze airflow is carried out deep or light separation, one end of elbow structure is that the other end of breeze airflow inlet and elbow structure branches into two outlets, wherein, outlet is positioned at the radially outer position of elbow and is connected with the pipe 11 of burner cylindrical shell, pipe provides the thick coal culm that goes out through concentrating and separating air-flow in being used to, and another outlet is positioned at the radially inner position of elbow and be connected with the outer tube 12 of burner cylindrical shell, is used to the outer tube and the toroidal cavity between the interior pipe that burn the device cylindrical shell that the thin powdered coal that goes out through concentrating and separating air-flow is provided.At this, an end opposite with its outlet of toroidal cavity seals, and enters burner hearth participation burning with the thin powdered coal air-flow that helps flowing in this toroidal cavity.
Oil gun 2 inserts along the breeze airflow direction in the interior pipe of burner cylindrical shell 1, and the scope of the angle α of the interior tubular axis line of the axis of oil gun 2 and burner cylindrical shell 1 is 0 °≤α≤90 °.Oil gun 2 can be arbitrary form oil guns such as mechanical atomization oil gun, air atomizing oil gun and gasification oil gun.
Elbow structure by pipeline inspissator 3, coal dust can be carried out deep or light separation, (height) thick coal culm enters by an above-mentioned outlet in the interior pipe of burner cylindrical shell 1 and is lighted by oil gun 2, (very) thin powdered coal then enters the burner tube external body by above-mentioned another outlet and discharges and (for example to enter outer tube, to spray into burner hearth then and participate in burning.After coal dust after concentrating in the interior pipe was lighted, volumetric expansion needed the light bisque of outer tube-be-come balance resistance, that is from the outer tube pressure release, preventing that central tube/interior pipe resistance is excessive, wind speed is too high, and cause and possibly can't successfully light a fire), thus play the effect that reduces the high concentrated coal powder wind speed.So because of coal dust is highly concentrated, and the igniting wind speed reduces greatly, lights can reduce the oil mass of oil gun 2, also can light for meager coal, anthracite that difficulty is fired.
