Abstract
The utility model relates to an initiating and combusting oil gun for fuel electric power plant, comprising an internal sleeve, an outer sleeve, a swirler, an oil branch plate, an outer atomizing chamber, and an internal atomizing chamber, wherein, the internal sleeve whose right end is conic and the outer sleeve whose right end is conic form a circular cavity; the swirler whose right side is the outer atomizing chamber is arranged on the internal sleeve, and the oil branch plate whose right side is the external atomizing chamber is arranged in the internal sleeve; the right end of the internal sleeve is the first outlet, and the right end of the outer sleeve is the secondary outlet. Firstly, the gas is introduced by the circular cavity and enters reelingly the outer atomizing chamber by the swirler; secondly, the gas is introduced from the internal sleeve, passing the oil branch plate, entering the external atomizing chamber, and mixing with the air in the outer atomizing chamber. The mixed gas finally spout has favorable ignition behavior.
Description
The utility model relates to a kind of thermal power plant igniting combustion supporting oil gun, belongs to the technical field of igniting combustion supporting device.
The thermal power plant of China, minority acts as a fuel with oil, all the other mainly act as a fuel with coal dust, coal dust can't burn in direct-fire, must use oil gun to light a fire, because some regional coal seam of China is relatively poor, the volatilization composition is few, ash amount is big, therefore must be provided with oil gun as combustion-supporting burning things which may cause a fire disaster, ability smooth combustion, oil gun just becomes the requisite igniting combustion supporting equipment in thermal power plant like this, but because boiler load is big, often need be with the oil gun of big flow, flow oil gun greatly, mink cell focus oil gun particularly, the cold conditions igniting is an insoluble difficult problem always, and its reason is that the spray gun atomizing is poor, the granular size of spraying has surpassed ignition limit, getting angry even can put, also be not only time-consuming but also oil consumption, and combustion case is also undesirable.
The purpose of this utility model is that a kind of thermal power plant igniting combustion supporting oil gun will be provided, and it can overcome above-mentioned shortcoming, and it is good that this oil gun has atomizing, flow is big, is easy to igniting, the advantage completely of burning, in gas circuit and oil circuit, set up cyclone and make the air-flow rotation, strengthened atomizing.
The purpose of this utility model is achieved in that
The interior cover right-hand member of oil gun is taper, the overcoat right-hand member also is taper, forms a ring cavity between the interior overcoat, in put a cyclone be housed, in the interior cover eddy flow oil dividing plate is housed also, the cyclone left side is a ring cavity, and the right side is an external atomizing chamber, and the overcoat right-hand member is the secondary outlet, interior cover right-hand member is once to export, interior cover inward turning flow point oiled-plate method, the right side is interior spray chamber, the cyclone right side is an external atomizing chamber in the overcoat.
Fig. 1 is the schematic diagram of igniting combustion supporting oil gun.
Now in conjunction with the accompanying drawings the structure of thermal power plant igniting combustion supporting oil gun is described in detail.
By Fig. 1, interior cover (2) right-hand member of oil gun is taper, the right-hand member of overcoat (1) also is a taper, form one ring cavity (3) between interior cover (2) and the overcoat (1), near taper place, interior cover (2) suit one helicla flute cyclone (4) or title spinning disk, in the interior cover (2) an eddy flow oil dividing plate (9) is housed also, the left side of eddy flow oil dividing plate (9) is oil circuit (10), right part is a spray chamber (8) in, overcoat (1) is ring cavity (3) on the left side of cyclone (4), the right side is external atomizing chamber (5), interior cover (2) right-hand member is once to export (7), overcoat (1) right-hand member is secondary outlet (6), atomizing air or steam are introduced by the ring cavity (3) between overcoat (1) and the interior cover (2), produce rotation and enter external atomizing chamber (5) through a spiral fluted cyclone (4), oil enters from the oil circuit (10) of interior cover (2), by eddy flow oil dividing plate (9), also produce rotation, enter interior spray chamber (8) then, enter external atomizing chamber (5) by once exporting (7) again, the gentle direction of rotation of oil can be identical, also can be opposite, this decides according to instructions for use, in external atomizing chamber (8), oil is with air infiltration with mix, last is with gushing out from secondary outlet (6), and formation has spinning momentum, and atomizing is spraying fully.
Compared with prior art, igniting combustion supporting oil gun in thermal power plant has following advantages:
1. be applicable to the situation of big flow, be easy to igniting, when cold conditions, also can instantaneously get angry.
2. atomization is good.
3. flame rigidity is strong, and penetration power is big.
4. cyclone is housed, makes the air-flow rotation, strengthen atomizing.
Claims (1)
1, a kind of thermal power plant igniting combustion supporting oil gun, it is characterized in that: interior cover (2) right-hand member of oil gun is taper, overcoat (1) right-hand member also is taper, interior overcoat (1), (2) form a ring cavity (3) between, on the interior cover (2) cyclone (4) is housed, (2) also are equipped with an eddy flow oil dividing plate (9) in the interior cover, cyclone (4) left side is ring cavity (3), the right side is external atomizing chamber (5), the overcoat right-hand member is secondary outlet (6), and interior cover (2) right-hand member is once to export (7), interior cover (2) inward turning flow point oiled-plate method (9), the right side is interior spray chamber (8), and the interior cyclone of overcoat (1) (4) right side is an external atomizing chamber.
