Abstract
The utility model relates to a low-oil ignition pulverized coal combustor applicable to meager coal and anthracitic coal, belonging to the field of pulverized coal combustion and comprising a combustor cylinder and an oil gun, wherein the oil gun is inserted in the combustor cylinder that is a retractable cylinder. The mechanical structure of the combustor utilizing special design solves the problems that the low-oil ignition pulverized coal combustor is poorer for adaptability to ignition wind speed, and bad in combustion effect in burning meager coal and anthracitic coal.
Description
Technical field
The utility model relates to a kind of few-oil ignition coal powder burner, relates in particular to a kind of meager coal and anthracitic few-oil ignition coal powder burner of being applicable to, belongs to the coal dust firing field.
Background technology
Few-oil ignition coal powder burner, present major part are based on the bituminous coal exploitation, because the bituminous coal fugitive constituent is higher, light than being easier to, and be stronger for igniting wind speed adaptability, so the engineering applicable cases is better.But for meager coal and anthracite, its adaptability to the igniting wind speed is relatively poor, and few-oil ignition coal powder burner effect is all relatively poor at present, and rate of economizing gasoline is lower.
The utility model content
For meager coal and anthracite, its adaptability to the igniting wind speed is relatively poor at present few-oil ignition coal powder burner for the utility model, and the deficiency that rate of economizing gasoline is lower provides a kind of meager coal and anthracitic few-oil ignition coal powder burner of being applicable to.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of meager coal and anthracitic few-oil ignition coal powder burner of being applicable to comprises burner cylindrical shell and oil gun, described oil gun inserts in the burner cylindrical shell, and described burner cylindrical shell is a scaling formula cylindrical shell.
On the basis of technique scheme, the utility model can be done following improvement.
Further, the axial or oblique insertion burner of described oil gun cylindrical shell.
Further, be α with an angle between described oil gun and the burner cylindrical shell, 0 °≤α≤90 ° wherein.
Further, the cylindrical shell of one-level at least of inner placement of described burner cylindrical shell and burner cylindrical shell coaxial line.
Further, described oil gun is mechanical atomization oil gun, air atomizing oil gun or gasification oil gun.
The beneficial effects of the utility model are: utilize the burner frame for movement of particular design to solve the few-oil ignition coal powder burner and be used to use that meager coal, anthracite are to igniting wind speed adaptability relatively poor, the problem of combustion efficiency difference, application prospect is extensive, has very huge market value.
Description of drawings
Fig. 1 is applicable to the structural representation of meager coal and anthracitic few-oil ignition coal powder burner for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Fig. 1 is applicable to the structural representation of meager coal and anthracitic few-oil ignition coal powder burner for the utility model.As shown in Figure 1, described meager coal and the anthracitic few-oil ignition coal powder burner of being applicable to comprises burner cylindrical shell 1 and oil gun 2, and described oil gun 2 inserts in the burner cylindrical shell 1.Described burner cylindrical shell 1 is a scaling formula cylindrical shell.Described oil gun 2 axial or oblique insertion burner cylindrical shells 1.Be α with an angle between described oil gun 2 and the burner cylindrical shell 1,0 °≤α≤90 ° wherein.The cylindrical shell of one-level at least with burner cylindrical shell 1 coaxial line can be placed in described burner cylindrical shell 1 inside, also can not place this cylindrical shell.Described oil gun 2 is mechanical atomization oil gun, air atomizing oil gun, gasification oil gun or other forms of oil gun.
The structure of described burner cylindrical shell 1 is a scaling formula cylindrical shell, also promptly amplifies earlier and dwindles.Generally once distinguished and admirable speed is higher, and meager coal, anthracite difficulty catch fire, so normal burner cylindrical shell igniting effect is relatively poor, existing the advanced row of burner cylindrical shell is amplified, to reduce once distinguished and admirable speed, improve the igniting effect.After high concentration pulverized coal entered burner cylindrical shell 1, the coal dust flow velocity was greatly diminished, and then by the oily flame ignition of high temperature, meager coal, anthracite coal dust then can be lighted rapidly.And primary air velocity does not allow long-term low cruise in the actual engineering, so after treating that coal dust is lighted, again by the dwindling of burner cylindrical shell, to improve primary air velocity to normal level.Therefore,, both can realize meager coal, the anthracitic needs of lighting, can guarantee once again that distinguished and admirable speed can not cross low and influence original system safety by this scaling formula burner cylindrical shell.When a large amount of fuel-economizing can be realized, also guarantee the security of unit by this structure.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
